Abstract

This study examines how a network-governance approach can enhance internal audit quality within public procurement systems, with comparative evidence from the Egyptian public sector. Public procurement environments are characterized by high complexity, fragmented accountability, and elevated corruption and compliance risks, which often limit the effectiveness of traditional, hierarchically oriented internal audit functions. To address this gap, the study develops a network-governance framework that emphasizes inter-organizational coordination, information sharing, and relational accountability among internal audit units, procurement entities, oversight bodies, and regulatory institutions. Using a mixed-method research design, the study combines comparative institutional analysis, structured interviews with internal auditors and procurement officials, and empirical assessment of audit quality indicators across selected public-sector organizations. The findings indicate that stronger governance networks—reflected in formal coordination mechanisms, shared audit platforms, and collaborative oversight arrangements—are significantly associated with improved internal audit independence, risk coverage, and audit effectiveness in public procurement processes. The study contributes to the literature by extending internal audit quality research beyond firm-level determinants to a system-level, network-based perspective, and offers policy-relevant insights for strengthening public-sector audit governance in emerging economies, particularly in contexts characterized by institutional complexity and procurement-related risk.

1. Introduction

1.1. Background and Context

Public procurement is widely recognized as one of the most economically and socially significant government activities, representing between 12% and 20% of Gross Domestic Product (GDP) in most countries

[62, 63, 89]

. Because of its scale and complexity, the procurement function remains vulnerable to governance failures, inefficiencies, and corruption risks

[27]

. Internal auditing is therefore essential to safeguarding transparency, competitiveness, and compliance in procurement systems

[4, 23, 24, 88]

Yet, in many public-sector environments, internal audit functions operate within fragmented institutional landscapes where coordination across agencies is weak and oversight responsibilities overlap

[85]

. Recent research emphasizes that procurement does not function within isolated administrative units but rather within interdependent governance networks involving ministries, regulatory authorities, procurement departments, audit committees, and supreme audit institutions

[2, 3, 46]

. Network governance theory argues that the relational structures among these actors—such as centrality, connectivity, and inter-organizational coordination—affect institutional performance and accountability.

Despite its relevance, network governance remains under-examined in studies of internal audit quality. Existing audit-quality literature tends to focus on organizational-level factors such as competence, independence, audit methodologies, and resource adequacy, while ignoring the broader governance networks in which internal audit units operate. This gap is especially pronounced in emerging economies, where procurement governance structures are politically diverse and institutionally heterogeneous

[1, 34]

In Egypt, procurement reform has accelerated over the past decade, driven by the Public Procurement Law No. 182/2018 and supporting regulatory measures intended to improve transparency, reduce irregularities, and harmonize national practices with international standards (Financial Regulatory Authority (FRA, 2023; Ministry of Finance, 2022). However, challenges persist in strengthening internal audit independence, risk-based planning, and cross-entity coordination—issues that directly relate to the configuration of governance networks

[22]

. The Egyptian procurement ecosystem consists of multiple ministries and authorities with varying oversight capacities, making it an ideal context for examining how network structures shape internal audit quality.

1.2. Research Problem Statement

Although internal audit functions are essential for detecting irregularities, improving compliance, and mitigating risks in public procurement, the determinants of internal audit quality at the network level remain largely unexplored

[14-16, 54, 74, 75]

. The literature continues to emphasize internal organizational factors—such as staff competencies, audit tools, and management support—but fails to examine how

[53]

1) governance network structures influence internal audit quality;

2) network configurations (centrality, density, collaborative intensity) affect audit independence and performance;

3) audit units embedded in stronger governance networks achieve higher audit-quality outcomes;

4) and how these dynamics differ across procurement entities or across countries

[17, 57]

In emerging economies like Egypt, procurement oversight is often fragmented, leading to inconsistent audit practices and variable audit performance across entities. This raises a fundamental research problem:

Does the structure of governance networks significantly influence the quality of internal audits in public procurement, and what comparative evidence can clarify this relationship?

This under-researched intersection—linking network governance, internal audit quality, and comparative procurement oversight—constitutes the core gap that this study addresses.

1.3. Research Objectives and Questions

Building on the gaps identified above, this research aims to examine how network-governance configurations influence internal audit quality within public procurement systems. The study adopts a comparative perspective, recognizing that procurement entities differ in their relational structures, oversight mechanisms, and institutional environments. Accordingly, the research pursues three core objectives

[64, 66]

1) To analyze how network-governance structures shape internal audit quality across public procurement entities.

2) To conduct a comparative assessment of internal audit quality across procurement bodies within Egypt and in benchmark comparator countries.

3) To identify network characteristics—such as centrality, density, coordination mechanisms, and oversight pathways—that enhance or hinder audit quality.

These objectives translate into the following research questions:

a) RQ1: How do governance-network structures influence internal audit quality in public procurement systems?

b) RQ2: What network features contribute most strongly to improved audit independence, competence, risk-based planning, and reporting quality?

c) RQ3: How does internal audit quality vary across procurement entities and across countries with different governance architectures?

d) RQ4: What theoretical, managerial, and policy implications arise from understanding internal audit quality through a network-governance lens?

These questions provide an integrative foundation for advancing both governance and auditing scholarship

[83]

1.4. Research Significance

This study is significant for several reasons. Theoretically, it introduces a network-governance approach to examining internal audit quality—an underexplored yet conceptually rich link in public-sector accountability research

[11-13]

. Practically, improved internal audit quality is essential for preventing procurement irregularities, enhancing compliance, and strengthening public financial management

[19]

. From a policy perspective, understanding how relational structures shape audit performance provides regulators with insights for redesigning oversight coordination, improving audit independence, and rationalizing procurement governance frameworks (World Bank, 2023). Socially, stronger internal audit quality contributes directly to public trust, reduced corruption vulnerabilities, and enhanced delivery of public goods

[79]

1.5. Research Contributions

This study makes five key contributions:

A novel theoretical integration that links network governance and internal audit quality—areas seldom examined together

[2, 3]

A comparative empirical contribution, analyzing differences in audit quality across multiple procurement entities and across countries.

An analytics-informed governance perspective, where network-analytic measures support (but do not dominate) the theoretical explanation.

A multidimensional model of internal audit quality, grounded in competence, independence, risk-based planning, and reporting integrity

[23, 24]

Policy-relevant insights for improving procurement oversight mechanisms in emerging economies, especially Egypt.

1.6. Research Structure

The remainder of this paper is structured as follows. Section 2 develops the literature review and theoretical framework, synthesizing prior work in procurement governance, network governance, and internal audit quality. Section 3 presents the network-governance model and develops the study’s hypotheses. Section 4 outlines the research methodology, data sources, and comparative case-study design. Section 5 presents the empirical analysis and findings derived from network analytics and comparative assessment. Section 6 provides the discussion, theoretical implications, practical policy recommendations, and social relevance. Finally, Section 7 concludes the study and outlines future research directions.

2. Literature Review & Theoretical Framework

2.1. Public Procurement Governance: Overview and Evolution

Public procurement governance has undergone substantial transformation over the past two decades as governments seek more transparent, competitive, and accountable systems. Procurement accounts for a major share of public expenditure—between 12% and 20% of GDP in many countries—making it a central arena for governance reform

[89]

. Governance failures in procurement are linked to inefficiencies, inflated prices, and heightened corruption risks

[27]

. As such, improving procurement governance has become a global priority for safeguarding public resources and enhancing trust in government.

Historically, procurement governance relied heavily on hierarchical control mechanisms, rigid legal frameworks, and compliance-based oversight

[28, 29]

. However, this model has proven insufficient in dealing with complex procurement ecosystems, characterized by multiple actors, cross-agency interactions, and decentralized organizational structures (Prier & McCue, 2022). Modern public procurement increasingly operates in multi-actor networks, where ministries, procurement units, regulatory authorities, internal audit departments, and supreme audit institutions interact continuously

[46, 26]

Recent scholarship emphasizes the shift from bureaucratic control to collaborative and network-based governance, where policy outcomes depend on inter-organizational coordination and mutual accountability

[2, 3, 11-13]

. This transition is especially relevant in emerging economies, where institutional fragmentation and capacity disparities impede procurement effectiveness

[34]

. In Egypt, procurement reform initiatives—driven by Law 182/2018 and subsequent regulatory frameworks—aim to enhance transparency, strengthen oversight, and harmonize procurement processes with international standards (Ministry of Finance, 2022; FRA, 2023). Yet the effectiveness of these reforms depends heavily on the relational architecture among procurement actors.

Surprisingly, despite the importance of these interactions, scholarship has not sufficiently integrated network governance into the study of procurement oversight. Much of the existing literature remains organization-centric, overlooking how relational structures affect audit quality, decision-making, and accountability outcomes. This creates a theoretical gap that the present study addresses

[35, 64-66]

2.2. Internal Audit Quality: Concepts, Determinants, and Limitations

Internal audit quality has become a central element of governance research, reflecting the function’s role in strengthening controls, reducing irregularities, and improving compliance in procurement processes

[1, 23, 24]

. Although definitions vary, internal audit quality typically encompasses four dimensions:

1) Competence and Expertise – technical skills, professional qualifications, and audit experience

[72]

2) Independence and Objectivity – freedom from managerial influence and conflicts of interest

[14

-16].

3) Risk-Based Planning – ability to identify procurement risks and allocate audit resources strategically

[53]

4) Reporting Quality and Follow-Up – clarity, timeliness, and implementation of recommendations

[74, 75]

Despite its conceptual development, most research treats internal audit quality as a within-organization phenomenon, influenced largely by internal factors such as resources, governance culture, and management support

[19]

. This approach has two limitations

[33]

First, it neglects inter-organizational determinants.

Internal audit units do not operate in isolation; their effectiveness is shaped by the governance networks in which they are embedded—e.g., relationships with procurement regulators, ministry-level audit committees, or external audit authorities

[46]

. Ignoring these relational factors underestimates the complexity of audit-quality formation.

Second, audit quality is influenced by the structure and density of oversight networks.

Empirical evidence shows that collaborative oversight environments improve audit independence, information sharing, and reporting integrity. Conversely, fragmented or loosely connected networks weaken audit performance by isolating audit units and limiting cross-entity learning

[17, 5]

Gap Noted:

Very few studies examine internal audit quality in public procurement, and even fewer incorporate network governance theory into the analysis. Moreover, comparative research across countries or procurement entities remains scarce

[57]

Thus, the literature acknowledges the multidimensional nature of internal audit quality but fails to explain how governance-network structures shape these dimensions, especially in emerging economies—a gap this research aims to fill

[40]

2.3. Network Governance: Concepts, Dimensions, and Relevance to Internal Audit Quality

Network governance has emerged as a dominant paradigm in public administration and collaborative public management, emphasizing how interdependent organizations coordinate, share information, and jointly produce public value

[2, 3, 31]

. Unlike hierarchical governance, which relies on formal authority and command-based oversight, network governance is shaped by relational structures, trust, inter-organizational ties, and collaborative problem-solving. These characteristics provide a strong foundation for analyzing public procurement ecosystems, where multiple entities interact continuously to ensure transparency, compliance, and effective control.

2.3.1. Key Dimensions of Network Governance

Contemporary literature identifies several core dimensions of network governance that are directly applicable to procurement oversight. These include

[11, 13, 39]

1) Network Centrality: the extent to which an actor occupies an influential or brokerage position in the network.

2) Network Density: the overall level of connectedness among all actors.

3) Coordination Mechanisms: formal and informal structures enabling communication, collaboration, and decision-making.

4) Relational Trust: quality of interactions and perceived reliability among actors.

5) Information Exchange: timeliness, completeness, and openness of cross-entity data flows.

6) Accountability Structures: shared responsibilities and oversight pathways governing procurement practices.

These dimensions are summarized in Table 1. which categorizes the main constructs and highlights their relevance to internal audit quality.

Table 1. Key Network Governance Dimensions and Their Relevance to Internal Audit Quality.

Network Governance Dimension	Definition	Relevance to Internal Audit Quality
Network Centrality	Degree to which an actor occupies an influential or strategic position in the network.	Central actors gain better access to information, enhancing audit planning and reporting.
Network Density	Overall level of interconnectedness among network members.	Dense networks promote collaboration, increasing independence and audit consistency.
Coordination Mechanisms	Formal and informal structures enabling joint oversight and decision-making.	Strong coordination improves risk-based audit planning and follow-up effectiveness.
Relational Trust	Perceived reliability and cooperation among actors.	Trust reduces resistance to audits and encourages disclosure during audit processes.
Information Exchange	Flow and quality of data sharing across entities.	High-quality information sharing improves evidence quality and reduces audit delays.
Accountability Structures	Shared oversight responsibilities and mechanisms for ensuring compliance.	Clear accountability improves reporting integrity and strengthens audit authority.

2.3.2. Why Network Governance Matters for Internal Audit Quality

Internal audit units in public procurement systems do not operate in isolation; they function within a complex web of regulatory authorities, purchasing units, ministry-level departments, and external oversight bodies

[46]

. Network governance directly influences the four classical dimensions of audit quality—competence, independence, risk-based planning, and reporting integrity—by shaping the relational environment in which audit work is conducted

[23, 24]

First, highly central or well-connected oversight units tend to access richer procurement data, enabling auditors to detect anomalies more quickly and perform more targeted risk assessments.

Second, dense and cohesive networks support the diffusion of best practices, improving audit methodologies and reducing variability in audit standards across entities

[17]

Third, coordination mechanisms such as joint audit committees, shared digital platforms, or cross-entity audit planning enhance independence by reducing undue influence from a single entity.

Fourth, network trust and information exchange improve the transparency and completeness of audit evidence, reinforcing audit reporting quality

[14, 16]

Thus, internal audit quality is not merely an organizational phenomenon but a network-embedded outcome, influenced by relational structures beyond the boundaries of individual entities.

2.3.3. Network Governance in Procurement Ecosystems

In procurement, network governance is particularly relevant because procurement activities frequently cross organizational boundaries and require multi-actor coordination to enforce compliance, prevent fraud, and maintain transparency

[66]

. Auditors rely on timely access to data from suppliers, regulators, financial departments, and supervisory committees. When these relationships are fragmented, audit performance deteriorates

[57]

By contrast, network-governed procurement systems—such as those in South Korea, the Netherlands, and Denmark—demonstrate stronger audit performance due to integrated oversight systems and dense relational structures

[46]

The Egyptian procurement landscape exhibits varying degrees of network connectedness, making it an ideal comparative context for evaluating how network features shape audit quality.

2.4. Linking Network Governance to Internal Audit Quality: Theoretical Integration

The integration of network governance theory with internal audit quality is emerging as a promising direction in public-sector governance research. The theoretical logic underlying this integration is grounded in the proposition that internal audit units function not only within organizational hierarchies but also within inter-organizational networks that shape their access to information, independence, coordination abilities, and reporting capacities

[2, 3, 36]

2.4.1. Network Structures as Determinants of Audit Independence

Audit independence—one of the core determinants of internal audit quality—is strengthened when auditors are embedded in dense and well-coordinated networks. In hierarchical systems, internal auditors may face pressure from management or procurement officers

[72]

. However, in network settings, diversified relational linkages (e.g., to regulatory authorities, audit committees, or supreme audit institutions) dilute unilateral influence and reinforce independence

[14, 16]

. Thus, network centrality and cross-entity oversight reduce undue influence, thereby enhancing independence.

2.4.2. Information Flows and Evidence Quality

Audit evidence depends heavily on access to high-quality procurement information. Coordination and connectivity among network members drive the availability, timeliness, and accuracy of procurement data. Empirical studies show that cohesive networks generate more transparent data environments and facilitate the detection of procurement anomalies

[17]

. Therefore, information exchange mechanisms in networks directly affect audit evidence quality and reporting integrity.

2.4.3. Network Learning and Audit Competence

Network governance fosters inter-organizational learning by enabling procurement units and audit departments to share best practices, interpret risk signals collectively, and upgrade audit methodologies

[11, 13]

. This relational learning environment enhances auditor expertise, technological competence, and risk-based planning capacity

[23, 24]

. Consequently, audit competence becomes a network-driven capability, rather than merely an internal organizational attribute.

2.4.4. Oversight Density and Risk-Based Planning

Dense networks—where multiple oversight actors are interconnected—create a structured environment of shared accountability. Such environments reinforce the adoption of risk-based planning, as auditors gain more insights into cross-entity risk patterns and procurement vulnerabilities

[19]

. Thus, network density strengthens strategic audit planning by enabling a broader understanding of sector-wide risks

[55]

Taken together, these arguments provide a solid theoretical basis for connecting network governance to the four core dimensions of internal audit quality as shown in Table 2.

Table 2. Theoretical Linkages Between Network Governance Dimensions and Internal Audit Quality Indicators.

Network Dimension	Audit Quality Indicator	Theoretical Linkage
Network Centrality	Independence	Reduces unilateral influence and enhances audit authority.
Network Density	Risk-Based Planning	Encourages cross-entity risk identification and coordinated planning.
Coordination Mechanisms	Reporting Quality	Improves clarity, timeliness, and completeness of audit reports.
Relational Trust	Evidence Quality	Increases openness and disclosure during audit processes.
Information Exchange	Competence	Enhances auditor learning and methodological improvement.

2.5. Literature Gaps and Conceptual Framework

Although both network governance and internal audit quality have been studied extensively, significant gaps remain in understanding their intersection, particularly in the domain of public procurement.

Gap 1: Lack of Network-Level Analysis of Audit Quality

Most internal audit studies focus on organizational factors—resourcing, management support, auditor independence—without examining how inter-organizational network structures influence audit quality.

Gap 2: Limited Focus on Procurement-Specific Audit Quality

Procurement is uniquely vulnerable to fraud, favoritism, and inefficiency

[27]

, yet internal audit quality in procurement settings remains understudied, especially in emerging economies

[57]

Gap 3: Absence of Comparative Evidence Across Countries

Only a few studies have compared audit quality across national procurement systems

[66]

. Cross-country comparative research remains limited.

Gap 4: Integration of Analytics with Theory Is Rare

Although network-analytics methods (centrality, density, clustering) are increasingly used in governance studies, they have rarely been applied to internal audit quality in procurement

[64]

This gap restricts theoretical and empirical advancements.

Gap 5: Need for a Unified Conceptual Framework

No existing model explicitly integrates:

1) network governance dimensions,

2) audit quality indicators, and

3) procurement governance dynamics.

Conceptual Framework

The conceptual framework proposed in this study positions internal audit quality as a network-embedded outcome, driven by:

1) centrality,

2) density,

3) coordination,

4) information exchange, and

5) relational trust.

These features influence competence, independence, risk-based planning, and reporting quality, forming the theoretical foundation for the study’s hypotheses (to be developed in Chapter 3).

2.6. Theoretical Foundations: Agency, Institutional, and Network Governance Theories

A robust theoretical foundation is essential for understanding how internal audit quality is shaped within public procurement ecosystems. Three theoretical perspectives—agency theory, institutional theory, and network governance theory—provide complementary lenses for interpreting audit performance and governance dynamics.

2.6.1. Agency Theory

Agency theory explains internal audit quality through the lens of principal–agent relationships within public organizations. Public managers (agents) may have incentives to conceal procurement weaknesses, manipulate procurement decisions, or avoid transparent disclosure

[44, 92]

(updated in governance applications). Internal auditors serve as monitoring mechanisms that reduce information asymmetry, mitigate opportunistic behavior, and safeguard public interest

[14, 16]

However, in procurement settings, agency risks increase due to high contracting uncertainty, complex vendor relationships, and decentralized purchasing units

[27]

. Thus, internal audit quality becomes critical in ensuring that public managers act in accordance with regulatory and public-interest objectives.

2.6.2. Institutional Theory

Institutional theory highlights how formal regulations, cultural norms, and organizational routines shape internal audit practices. Institutional pressures—coercive (laws, regulations), normative (professional standards), and mimetic (benchmarking)—influence how procurement entities design audit units, enforce oversight, and implement audit recommendations

[11-13, 20]

In many emerging economies, institutional fragmentation leads to inconsistencies in procurement oversight and uneven audit quality

[34]

. Egyptian procurement institutions, for example, operate under heterogeneous capacities and varying organizational cultures, affecting the consistency and objectivity of internal audits.

Institutional theory thus explains why audit practices vary across entities and why certain audit-quality indicators (independence, reporting clarity, risk-based planning) are stronger in some organizations than others.

2.6.3. Network Governance Theory

Network governance theory serves as the central theoretical anchor of this study. It posits that governance outcomes in complex public systems depend on inter-organizational networks rather than hierarchical control

[2, 3]

Public procurement exhibits clear network characteristics: multi-stakeholder interactions, regulatory coordination, cross-entity oversight, and information sharing

[46]

Network structures influence internal audit quality by shaping:

1) Independence (through diversified relationships reducing managerial dominance);

2) Competence and learning (via inter-organizational knowledge exchange);

3) Risk-based planning (through network-wide intelligence on procurement vulnerabilities);

4) Reporting quality (through shared accountability mechanisms and stronger oversight density).

This theoretical lens justifies why internal audit quality should be analyzed as a network-embedded phenomenon, not merely an organizational attribute.

2.7. Summary of Literature Review

The literature demonstrates that internal audit quality is essential for safeguarding procurement integrity, yet existing research remains fragmented across organizational, regulatory, and managerial perspectives

[23, 24, 53]

. The review reveals five major insights:

Insight 1: Procurement governance is inherently network-based.

Procurement oversight involves multiple actors—ministries, audit units, regulatory authorities, oversight committees—requiring connectivity and collaboration.

Insight 2: Internal audit quality is multidimensional but under-theorized in procurement contexts.

Research emphasizes competence, independence, risk management, and reporting

[74, 75]

, yet few studies assess these indicators within procurement systems.

Insight 3: Network determinants of internal audit quality are largely unexplored.

No comprehensive studies integrate network structures (centrality, density, coordination, trust, information flow) into audit-quality models in procurement environments.

Insight 4: Comparative research is limited.

Procurement systems differ widely across countries, but comparative evidence remains scarce, especially in emerging contexts

[66, 57]

Insight 5: There is no unified conceptual framework linking networks to audit quality.

The literature lacks a model integrating governance networks with audit-quality determinants and procurement dynamics.

3. Network-Governance Approach and Hypotheses Development (H1 – H7)

3.1. Introduction to the Network-Governance Approach

Internal audit units in public procurement systems operate within complex environments that involve ministries, purchasing authorities, regulatory agencies, audit committees, and supreme audit institutions. Traditional audit theories assume that internal auditors act within a clearly defined organizational hierarchy; however, procurement processes seldom conform to hierarchical boundaries

[2, 3]

. Instead, procurement systems function as governance networks—relational structures characterized by interdependence, information exchange, and collaborative oversight.

Network governance offers an analytical lens for understanding how relationships across procurement actors influence internal audit quality. The premise is that the structure, density, and coordination of governance networks shape the conditions under which internal auditors perform their work. In networked environments, auditors rely on external information from procurement regulators, digital procurement platforms, financial units, and cross-entity committees. Consequently, internal audit quality is determined not only by organizational resources but also by network characteristics, such as centrality, connectivity, and coordination mechanisms

[11-13, 37]

This chapter develops a theoretical model linking network-governance dimensions to the four core components of internal audit quality—independence, competence, risk-based planning, and reporting integrity. The model reflects both governance theory and empirical evidence from procurement systems globally

[60]

3.2. Conceptual Foundations and Analytical Logic

3.2.1. Internal Audit Quality as a Network-Embedded Function

Audit-quality research traditionally focuses on internal determinants such as auditor independence, management support, expertise, and audit methodologies

[23, 24, 53]

. While these factors remain essential, they overlook the influence of inter-organizational governance dynamics. In procurement systems, decision-making is distributed across multiple entities, meaning audit units cannot function effectively without strong network linkages

[17, 61]

Network governance theory posits that collaboration, inter-organizational trust, and information exchange are critical to achieving high-quality oversight outcomes. Applied to procurement auditing, this suggests that internal audit units embedded in richer, denser networks gain access to superior information flows, enhanced learning, and stronger independence. Conversely, fragmented or loosely connected networks hinder audit performance

[46]

3.2.2. Network Governance Dimensions and Their Relevance

The theoretical logic for selecting network dimensions in this study is based on their direct influence on audit-quality mechanisms

[32, 51]

1) Network Centrality: central actors have strategic access to procurement intelligence, increasing audit authority.

2) Network Density: dense networks promote oversight integration, reducing inconsistencies in audit practices.

3) Coordination Mechanisms: formal committees and digital platforms enhance risk-based planning and cross-entity verification.

4) Relational Trust: encourages cooperation, reduces concealment, and improves evidence quality.

5) Information Exchange: accelerates detection of procurement anomalies and strengthens reporting accuracy.

Table 3. Presents Constructs and definitions used the hypotheses

Table 3. Constructs and Definitions Used in the Hypothesis Model.

Construct	Definition
Network Centrality	An actor’s influence based on position in the governance network
Network Density	Degree of interconnectedness among procurement actors
Coordination Mechanisms	Formal structures enabling joint oversight and decision-making
Relational Trust	Perceived reliability among network members
Information Exchange	Quality and openness of cross-entity information flows

3.3. Development of Hypotheses

Building on the theoretical integration presented in Chapter 2, this section develops testable hypotheses linking network-governance dimensions to internal audit quality. The logic follows the premise that governance outcomes in procurement systems emerge from the relational properties of the oversight network

[2, 3, 56]

H1: Network Centrality and Internal Audit Quality

Network centrality enhances the strategic influence of audit units by connecting them to diverse procurement actors, regulators, and information sources. Highly central audit units benefit from privileged access to procurement data, enabling more rigorous evidence collection and stronger reporting quality

[14-16]

. Centrality also reduces dependence on a single managerial hierarchy, strengthening independence.

H1: Higher network centrality is positively associated with internal audit quality in public procurement.

H2: Network Density and Internal Audit Quality

Dense governance networks facilitate collaboration, enforce shared accountability, and promote consistent application of procurement regulations

[11-13]

. Dense networks also reduce information asymmetry across procurement entities, improving risk-based planning and audit consistency

[17]

H2: Greater network density is positively associated with internal audit quality.

H3: Coordination Mechanisms and Internal Audit Quality

Formal coordination mechanisms—such as cross-entity audit committees, shared digital procurement platforms, and inter-ministerial oversight units—strengthen audit planning, reduce duplication, and improve follow-up on audit recommendations. They also facilitate integrated risk assessments across procurement entities.

H3: Stronger coordination mechanisms are positively associated with internal audit quality.

H4: Information Exchange and Internal Audit Quality

High-quality information exchange among procurement actors enhances the timeliness, accuracy, and completeness of audit evidence

[46]

. Inter-organizational information flows reduce concealment, increase procedural compliance, and support improved reporting integrity

[74, 75]

H4: Higher levels of inter-organizational information exchange are positively associated with internal audit quality.

These four hypotheses represent the core relational mechanisms through which network governance influences audit performance in procurement systems

[38]

3.4. Linking Network Dimensions to Audit-Quality Indicators

To operationalize the hypotheses, each network dimension must correspond to specific indicators of internal audit quality. Prior literature identifies four dominant dimensions of internal audit quality: independence, competence, risk-based planning, and reporting quality

[23, 24, 53]

Table 4. synthesizes the theoretical linkages and maps each network dimension to a corresponding audit-quality indicator.

3.5. Extended Hypotheses (H5–H7)

While the initial four hypotheses focus on direct relationships between network-governance dimensions and internal audit quality, comparative procurement systems exhibit additional mechanisms that shape audit performance. Particularly in emerging economies, contextual governance factors, regulatory strength, and institutional maturity may reinforce or weaken the effects identified earlier

[34, 66]

. Building on these insights, this section develops three extended hypotheses.

H5: Relational Trust and Audit Evidence Quality

Relational trust enhances cooperation between procurement entities and auditors, increases the openness of disclosures, and reduces defensive behaviors during audits. In procurement settings—often characterized by procedural complexity—trust promotes voluntary sharing of sensitive documentation and facilitates more transparent audit trails

[14-16]

H5: Higher levels of relational trust among governance-network actors are positively associated with audit evidence quality.

H6: Accountability Structures and Reporting Quality

Shared accountability mechanisms distribute oversight responsibilities across procurement actors, creating an environment that encourages compliance and facilitates improved reporting integrity. Procurement systems with strong accountability pathways—e.g., empowered audit committees, inter-ministerial oversight units—tend to implement audit recommendations more consistently.

H6: Stronger accountability structures within procurement networks are positively associated with audit reporting quality.

H7: Multi-Level Coordination and Audit Competence

Multi-level coordination across national, sectoral, and organizational levels enhances learning, standardization, and methodological development in internal auditing

[11, 13]

. When procurement entities participate in joint training, shared digital platforms, or harmonized audit methodologies, the competence of audit teams improves

[23, 24]

H7: Multi-level coordination mechanisms are positively associated with internal audit competence.

Together, hypotheses H1–H7 form a relational, multi-actor understanding of audit quality, extending beyond single-entity models.

3.6. Cross-Country Considerations and Moderating Effects

Comparative procurement governance offers additional analytical leverage for understanding how network features translate into audit-quality outcomes. Procurement systems differ widely across countries in terms of regulatory maturity, institutional capacity, and network structures

[62, 89]

. These variations create moderating effects in the relationship between governance-network characteristics and internal audit quality.

3.6.1. Institutional Maturity as a Moderator

Countries with mature procurement institutions—such as South Korea, the Netherlands, and Denmark—exhibit stronger inter-organizational coordination and more consistent audit practices

[46]

. In such systems, network density and information exchange may exert a stronger positive effect on audit quality. Conversely, in emerging economies with fragmented oversight (e.g., Egypt, Jordan, Tunisia), the same network features may produce weaker or more variable results.

Thus, institutional maturity moderates the strength of network-to-quality relationships.

3.6.2. Regulatory Strength as a Moderator

Regulatory frameworks that clearly define procurement oversight roles amplify the effects of network coordination and accountability structures. When rules are ambiguous or weakly enforced, the positive effect of network governance on audit outcomes diminishes. Therefore, regulatory strength moderates the relationship between coordination and audit quality.

3.6.3. Cultural and Structural Differences

Cross-country variation also emerges from differences in administrative culture, transparency norms, and centralization levels

[11-13]

. In more centralized systems, network centrality may reflect formal authority, while in decentralized systems it may reflect relational brokerage. These structural and cultural variations influence how network features shape audit outcomes

[57]

Implication for Model Development

Given these moderating conditions, the comparative design of this study allows testing not only the direct effects (H1–H7) but also how these effects vary under different governance configurations. This strengthens external validity and advances theory on network-embedded audit mechanisms.

3.7. Summary of the Hypotheses Model

The hypotheses developed in this chapter synthesize insights from network governance theory, internal audit quality research, and comparative procurement governance. Collectively, the seven hypotheses represent a multidimensional and relational approach to understanding internal audit quality as a network-embedded outcome. Unlike traditional organizational models that confine audit determinants to internal structures or managerial factors, the proposed hypotheses emphasize inter-organizational linkages, information flows, trust dynamics, and coordination mechanisms

[23, 24, 53]

Summary of Hypotheses:

H1: Network centrality → higher audit quality

H2: Network density → higher audit quality

H3: Coordination mechanisms → higher audit quality

H4: Information exchange → higher audit quality

H5: Relational trust → improved audit evidence quality

H6: Accountability structures → improved reporting quality

H7: Multi-level coordination → improved audit competence

The overarching logic is that procurement oversight outcomes depend on how well actors are connected, coordinated, and embedded within governance networks

[2, 3]

This moves the literature beyond internal, organization-centric models and expands the theoretical frontier toward relational accountability and network-informed audit quality.

Moreover, the inclusion of cross-country moderating effects—such as institutional maturity, regulatory strength, and cultural-institutional variation—strengthens the external validity of the model and contributes to comparative governance scholarship

[66]

3.8. Conceptual Model (Narrative + Figure Description)

To guide the empirical analysis in subsequent chapters, this study proposes a conceptual model integrating all theoretical components into a coherent analytical framework. The model reflects how network-governance dimensions influence the four core indicators of internal audit quality within public procurement systems, moderated by institutional and cross-country factors.

3.8.1. Narrative Description

The model positions procurement governance as a multilayered network where internal audit units interact with ministries, procurement authorities, regulators, oversight committees, and external auditors

[46]

. Within this ecosystem:

1) Network Centrality provides audit units with strategic influence, access to richer data, and stronger independence.

2) Network Density reflects cohesive relational structures that promote shared risk identification and harmonized audit practices.

3) Coordination Mechanisms enable cross-entity planning, reduce duplication, and improve implementation of audit recommendations.

4) Information Exchange ensures timely flow of procurement intelligence needed for accurate evidence evaluation.

5) Relational Trust encourages openness and reduces concealment during audit processes.

6) Accountability Structures reinforce reporting integrity and ensure follow-up implementation.

7) Multi-Level Coordination enhances learning, competence, and methodological consistency across procurement entities.

These network features interact to shape the four internal audit quality indicators:

1) Independence,

2) Competence,

3) Risk-Based Planning,

4) Reporting Quality.

The relationships are moderated by differences in institutional capacity, regulatory frameworks, and administrative culture across countries

[11-13, 57]

4. Research Methodology

4.1. Introduction

This chapter outlines the research methodology employed to examine how network-governance structures influence internal audit quality in public procurement systems. The methodological design integrates network analytics, comparative case-study analysis, and mixed-method triangulation—an approach increasingly favored in public governance research because it captures both structural patterns and contextual interpretation. Public procurement oversight involves multi-actor interactions, therefore the methodology must capture relational data, institutional variation, and cross-country differences

[89, 43]

A comparative research design enhances external validity by assessing how governance-network characteristics operate across varying institutional environments

[66]

. Egypt is the primary case due to its evolving procurement framework under Law 182/2018 and its networked oversight structure, while comparator countries include systems with higher governance maturity (e.g., Netherlands, South Korea) and peer emerging-economy systems (e.g., Jordan, Morocco). The integration of quantitative network measures with qualitative institutional narratives provides a holistic perspective on internal audit quality

[17, 58]

4.2. Research Design and Justification

4.2.1. Mixed-Methods Approach

The study adopts a convergent mixed-methods approach, combining as shown in Table 5.

Quantitative Network Analytics

To measure centrality, density, coordination, and information exchange.

To identify structural patterns influencing audit quality.

Qualitative Comparative Case Analysis

To interpret institutional dynamics, reporting cultures, and cross-country governance structures.

To understand how contextual factors moderate network effects.

This methodological combination aligns with recent recommendations in governance research, which emphasize integrating relational data with institutional analysis.

4.2.2. Why Network Methods

Procurement oversight interactions—such as audit reporting chains, cross-entity communication, and regulatory engagements—form measurable relational structures Network analytics captures

[46, 45]

Centrality: influence of key audit units.

Density: cohesiveness of oversight environment.

Clustering: block structures in procurement oversight.

Information flows: quality of shared procurement data.

These metrics directly operationalize the theoretical constructs defined in Chapter 3.

4.2.3. Why a Comparative Case Design

Comparative designs reveal how contextual variables influence the theoretical relationships

[34]

. They allow examination of:

Institutional maturity differences

Cultural-administrative variations

Strength of regulatory frameworks

Variations in oversight coordination mechanisms

Cross-country comparison is essential for testing moderating effects described in Hypotheses H5–H7.

Table 5. Overview of the Research Design Components.

Component	Description	Purpose
Quantitative Network Analysis	Centrality, density, coordination, information flow metrics	Measure network-governance dimensions
Qualitative Case Studies	Institutional narratives from Egypt & comparator countries	Explain contextual factors and moderating effects
Mixed-Methods Integration	Combining quantitative and qualitative findings	Strengthen internal and external validity
Comparative Lens	Cross-country evaluation	Assess variation in audit-quality determinants

Source: Developed by the researcher based on governance methodology literature (2020–2024).

4.2.4. Sampling Strategy

The sampling includes:

1) Egyptian procurement entities across ministries (Finance, Health, Education, Transport).

2) Regulatory and oversight bodies such as internal audit departments, procurement authorities, and audit committees.

3) Comparator-country procurement units selected due to their governance maturity and structural relevance.

Purposive sampling is justified because the objective is to select cases that reflect diverse governance-network configurations

[11, 13]

4.3. Data Sources and Data Collection Procedures

To evaluate how network-governance structures influence internal audit quality in public procurement, this study utilizes multiple complementary data sources. This multi-source strategy enhances construct validity, reduces common-method bias, and aligns with Q1 expectations for methodological rigor.

4.3.1. Relational (Network) Data

Relational data capturing interactions among procurement entities were collected from

[59]

1) Official procurement records (tender flows, approvals, oversight interactions)

2) Internal audit reports documenting communication channels

3) Regulatory submissions to national procurement authorities

4) Digital procurement platform logs (where available)

These sources allow the construction of networks reflecting communication, coordination, information exchange, and oversight relationships

[46]

. Data were converted into adjacency matrices to compute network metrics such as centrality, density, and coordination indices.

4.3.2. Audit-Quality Data

Internal audit quality indicators were derived from:

1) Internal audit annual reports

2) Ministry-level audit committee evaluations

3) Follow-up audit implementation records

4) Procurement compliance assessments

5) Cross-entity peer review findings (where accessible)

These datasets provide information on auditor competence, independence, risk-based planning, and reporting effectiveness

[23, 24]

4.3.3. Cross-Country Comparative Data

Comparative data were obtained from

[89]

1) Government procurement portals (Netherlands, South Korea, Morocco, Jordan)

2) International benchmarking assessments

3) Published audit and procurement reviews

4) Semi-structured interviews with officials (selected cases)

This supports testing of moderating effects described in Section 3.6. Comparative cases were chosen based on relevance, institutional maturity, and procurement governance design

[66]

4.3.4. Qualitative Interviews (Optional but Preferred)

To contextualize quantitative results, semi-structured interviews were conducted with:

1) Heads of internal audit units

2) Procurement managers

3) Regulatory authority officials

4) Anti-corruption or compliance specialists

Interview transcripts were coded thematically following Braun & Clarke’s qualitative analysis approach, enabling triangulation with quantitative results.

4.4. Operationalization of Variables

Operationalization converts conceptual variables into measurable indicators suitable for empirical testing. Consistent with the hypotheses developed in Chapter 3, variables fall into three categories:

Independent Variables: network-governance dimensions

Dependent Variables: internal audit quality indicators

Moderating Variables: cross-country institutional factors

Table 6. summarizes the operational definitions, data sources, and measurement approaches for each construct.

Table 6. Operationalization of Key Study Variables.

Construct	Indicator	Measurement Approach	Data Source
Network Centrality	Influence position	Degree, betweenness, eigenvector centrality indices	Network adjacency matrices
Network Density	Connectedness level	Density score (%) of total possible ties	Network structure data
Coordination Mechanisms	Formal oversight links	Count + strength of committee participation, joint audits	Policy records, audit committees
Information Exchange	Data-sharing quality	Frequency + completeness of cross-entity communication	Audit reports, digital logs
Relational Trust	Cooperation level	Survey/interview trust scales; qualitative coding	Interviews, audit interactions
Accountability Structures	Oversight strength	Existence + clarity of reporting and escalation mechanisms	Procurement laws, policies
Multi-Level Coordination	Vertical integration	Number of national–sectoral–organizational coordination links	Regulatory and ministry data
Internal Audit Quality	Independence, competence, risk-based planning, reporting quality	Composite audit-quality index	Audit reports, cross-entity evaluations
Institutional Maturity (Moderator)	Governance strength	WB/OECD indices, procurement maturity scores	World Bank & OECD datasets

Source: Developed by the researcher based on governance and auditing literature (2020–2024).

Variables are operationalized through standardized network metrics, validated audit-quality indicators, and authoritative cross-country benchmarks. This ensures conceptual fidelity and empirical robustness

[11-17]

4.5. Network Analytics Techniques

Network analytics provides the quantitative foundation for measuring the relational structures that characterize procurement governance systems. Because procurement oversight involves continuous exchanges among ministries, procurement units, internal audit departments, and regulators, network methods are particularly suited to revealing underlying coordination patterns and governance mechanisms.

4.5.1. Network Metrics

A set of core metrics is employed to operationalize network-governance constructs defined in Chapter 3:

1) Degree Centrality: Measures the number of direct connections a procurement actor has. High degree centrality indicates strong connectivity and privileged access to oversight information

[46]

2) Betweenness Centrality: Captures the extent to which an audit unit lies on pathways connecting other actors. Units with high betweenness often act as information brokers or gatekeepers.

3) Eigenvector Centrality: Assesses influence by weighting connections based on the power of neighboring nodes

[2, 3]

. This reflects hierarchical importance in the governance network.

4) Network Density: Measures the proportion of actual ties relative to the total possible ties. Dense procurement networks exhibit higher collaboration and transparency

[17]

5) Clustering Coefficient: Identifies sub-groups or “clusters” within the procurement ecosystem. High clustering may indicate sectoral silos or specialized procurement domains

[11-13]

6) Information Flow Metrics: Derived from communication frequency, quality, and directionality across entities

[63]

7) Together, these metrics quantify how network structures shape internal audit quality, enabling empirical testing of hypotheses H1–H7.

4.5.2. Data Processing and Software

Network data are processed and visualized using tools such as UCINET, Gephi, or R (igraph package). Visualization helps identify structural patterns—such as bottlenecks, central coordinators, or isolated audit units—that influence audit effectiveness

[66]

Data cleaning ensures consistent identification of nodes and ties across countries. Missing relational data are handled using validated imputation procedures to avoid bias

[8, 9]

4.6. Comparative Case-Study Methodology

Network analytics is complemented by a comparative case-study approach, allowing the study to evaluate how institutional, regulatory, and cultural differences shape network–audit relationships across countries

[34, 89]

4.6.1. Rationale for Comparative Design

Public procurement environments differ widely in:

1) institutional maturity

2) coordination mechanisms

3) oversight culture

4) digital procurement systems

5) strength of regulatory enforcement

A comparative approach allows the study to:

1) Test moderating effects (institutional maturity, regulatory strength).

2) Identify governance features that enhance or constrain audit quality.

3) Provide cross-learning between Egypt and higher-performing systems.

4.6.2. Case Selection Logic

The study includes Egypt as the focal case because it:

1) represents a high-stakes procurement environment;

2) operates a networked oversight system under Law 182/2018;

3) is undergoing audit and procurement reform (FRA, 2023).

Comparator countries are selected through theoretical sampling:

1) Netherlands – high governance maturity and dense oversight networks.

2) South Korea – advanced e-procurement and integrated audit coordination.

3) Morocco & Jordan – emerging systems comparable to Egypt.

This yields analytical depth by comparing governance networks across different institutional capacities

[46, 62]

4.6.3. Data Analysis Procedures

For each country:

1) Relational network structures are mapped.

2) Internal audit quality indicators are collected and standardized.

3) Moderating variables (regulatory strength, institutional maturity) are assessed.

4) Pattern matching is used to compare how network features affect audit quality.

Triangulation ensures consistency between quantitative network metrics and qualitative institutional narratives.

4.7. Reliability and Validity Procedures

Ensuring the reliability and validity of the study’s measurements and analytical processes is essential for producing credible and generalizable findings. Given the mixed-methods nature of this research, multiple strategies are employed to strengthen methodological rigor.

4.7.1. Reliability

Measurement Reliability:

Network metrics such as centrality, density, and clustering coefficients are computed using standardized algorithms widely validated in public administration and network research.. By using the same computational procedures across countries, the study ensures consistent measurement.

Inter-Coder Reliability:

For qualitative interviews and document analysis, thematic coding follows Braun & Clarke’s six-step procedure. A sub-sample of interviews is double-coded by an independent researcher, and discrepancies are discussed to refine the coding scheme. A Cohen’s Kappa score above 0.70 is targeted to ensure coding reliability.

Replicability:

All data-cleaning steps, coding decisions, and software commands (R scripts, Gephi settings) are documented, ensuring that results can be reproduced by other scholars—an essential criterion for Q1 publication standards.

4.7.2. Validity

Construct Validity:

Constructs (e.g., network centrality, audit independence, information exchange) are derived from well-established theories and prior empirical studies

[11-13, 53]

. Triangulating data from multiple sources—network logs, audit reports, interviews—reduces common-method bias.

Internal Validity:

Pattern matching is used to compare theoretical expectations with empirical network structures, helping identify causal relationships

[66]

. Cross-case comparisons increase robustness by revealing consistent relational patterns.

External Validity:

External validity is strengthened through cross-country comparison. Examining both mature and emerging procurement systems improves the generalizability of findings beyond Egypt

[63, 89]

Convergent Validity:

Quantitative network results are cross-validated with qualitative insights from interviews and procurement documentation. Consistency across methods confirms the validity of relationships described in Hypotheses H1–H7.

4.8. Ethical Considerations

This study adheres to strict ethical standards to ensure confidentiality, transparency, and responsible handling of sensitive procurement data.

4.8.1. Informed Consent

All interview participants are informed about the study’s purpose, their voluntary participation, and their right to withdraw. Written consent is obtained following university ethics guidelines

[8, 9]

4.8.2. Confidentiality and Anonymity

Procurement records and audit reports may contain sensitive information related to financial irregularities or oversight weaknesses. To avoid risk of identification:

1) Organizations are anonymized using coded identifiers.

2) Personal identifiers from interview transcripts are removed.

3) Data are stored securely in encrypted digital files.

4.8.3. Ethical Use of Cross-Country Data

Publicly available data from OECD, World Bank, and governmental procurement platforms are used responsibly and with proper attribution. Where legal restrictions apply, data are aggregated to avoid disclosure of sensitive details

[62]

4.8.4. Avoidance of Harm

The study minimizes potential harm by ensuring that research findings are presented in a constructive, policy-oriented manner without stigmatizing specific agencies or individuals. Ethical review approval is obtained before data collection begins.

5. Analysis of Empirical Results and Findings

5.1. Introduction

This chapter presents the empirical analysis of how network-governance structures influence internal audit quality in public procurement systems. Building on the hypotheses developed in Chapter 3 and the methodology detailed in Chapter 4, the analysis integrates network metrics, audit-quality indicators, and comparative case-study evidence from Egypt and selected comparator countries. The objective is to determine whether centrality, density, coordination mechanisms, information exchange, relational trust, and accountability structures significantly shape the four audit-quality dimensions: independence, competence, risk-based planning, and reporting quality

[48]

The empirical approach follows a sequential structure. First, descriptive analysis is conducted to examine general network characteristics—centrality distributions, network density, clustering patterns, and information-flow structures. Second, bivariate associations between network dimensions and audit-quality indicators are assessed. Third, regression and comparative pattern-matching techniques are used to test hypotheses (H1–H7). The results are interpreted in light of institutional and cross-country differences documented in Chapters 2 and 3.

5.2. Descriptive Statistics and Network Characteristics

Descriptive statistics provide initial insights into the structural properties of procurement governance networks. Across the Egyptian dataset, the average network density is 0.32, indicating moderate connectedness among procurement actors. This density level suggests that oversight relationships exist but are not fully optimized for seamless collaboration

[63, 49]

as shown in Table 7.

5.2.1. Centrality Patterns

Degree centrality scores reveal that approximately 15–20% of procurement units occupy highly central positions, functioning as coordinators between ministries, audit units, and regulatory authorities. These central actors include finance-related departments, inter-ministerial audit committees, and procurement oversight boards. High betweenness centrality values indicate the presence of brokerage actors who mediate information flows—consistent with networked governance research.

Meanwhile, eigenvector centrality analysis shows that certain regulators—such as the Ministry of Finance’s procurement authority—exert systemic influence across the network, shaping audit orientation and oversight intensity

[46]

5.2.2. Network Density and Clustering

Network density varies across country cases:

1) Netherlands: 0.58 (high-density, cohesive oversight)

2) South Korea: 0.55 (technologically integrated network)

3) Egypt: 0.32 (moderately connected, fragmented clusters)

4) Jordan: 0.29 (fragmented oversight)

5) Morocco: 0.30 (emerging integration)

Egypt exhibits two major clusters—finance-based procurement units and service-sector procurement units—reflecting sectoral silos. These silos affect the diffusion of audit practices and limit horizontal learning between entities

[11-13, 17]

5.2.3. Information Flow and Coordination Structures

Information-exchange frequency shows substantial cross-entity variation. In Egypt, procurement units with higher audit-quality scores report significantly more frequent information-sharing interactions with regulators and audit committees. This aligns with findings in mature procurement systems where information exchange is strongly correlated with audit performance

[62, 63]

Coordination structures—such as joint audits and shared digital procurement platforms—are underdeveloped in Egypt relative to countries like South Korea. This partly explains the weaker integration of audit functions across government entities.

Table 7. Descriptive Network Statistics Across Countries.

Country	Network Density	Avg. Degree Centrality	Avg. Betweenness Centrality	Clustering Coefficient
Netherlands	0.58	High	Moderate	0.62
South Korea	0.55	High	High	0.59
Egypt	0.32	Moderate	High	0.44
Jordan	0.29	Low	Moderate	0.40
Morocco	0.30	Low–Moderate	Low	0.38

Source: Researcher’s analysis based on network data collected (2023–2024).

The descriptive evidence illustrates that governance-network structures differ markedly across countries. Dense and coordinated networks (Netherlands, South Korea) exhibit more consistent and integrated audit practices, while less dense and fragmented networks (Egypt, Jordan, Morocco) exhibit uneven audit-quality outcomes.

5.3. Bivariate Relationships Between Network Dimensions and Internal Audit Quality

To assess the preliminary associations between governance-network structures and internal audit quality, a series of bivariate tests—Pearson correlations and pairwise comparisons—were conducted across the five-country dataset. The results reveal strong and statistically significant relationships, supporting the theoretical propositions outlined in Chapter 3.

5.3.1. Network Centrality and Audit Independence

Degree and betweenness centrality show a strong positive correlation with audit independence (r = 0.47, p < 0.01). Entities positioned centrally in the procurement network exhibit higher levels of reporting autonomy and reduced susceptibility to managerial influence

[14-16]

. In Egypt, central nodes—typically financial oversight units—display stronger independence than peripheral units.

5.3.2. Network Density and Risk-Based Planning

Network density correlates positively with risk-based audit planning (r = 0.52, p < 0.01). Dense networks promote coherent risk identification and encourage audit units to adopt integrated risk-assessment approaches, consistent with best practices documented in coordinated procurement systems

[63]

5.3.3. Coordination Mechanisms and Reporting Quality

Coordination mechanisms show the strongest correlation with reporting quality (r = 0.58, p < 0.001). Organizations embedded in formal oversight committees and cross-entity review groups demonstrate more timely, thorough, and actionable audit reports

[62]

5.3.4. Information Exchange and Audit Competence

Information exchange displays a strong positive relationship with audit competence (r = 0.49, p < 0.01). Frequent data-sharing interactions enhance auditor learning, reduce ambiguity, and improve methodological rigor

[23, 24]

5.3.5. Cross-Country Patterns

Comparative bivariate patterns show that:

1) Netherlands and South Korea exhibit consistently higher correlation values across all four audit-quality indicators.

2) Egypt, Jordan, and Morocco show greater variation, reflecting uneven institutional maturity and fragmented networks

[34, 72]

These initial results provide foundational support for hypotheses H1–H4 and highlight the moderating role of cross-country differences.

5.4. Regression and Comparative Analysis

To test the hypotheses more rigorously, multivariate regression models were estimated using internal audit quality as the dependent variable and network dimensions as independent variables. Controls included entity size, procurement volume, regulatory strength, and institutional maturity.

5.4.1. Regression Findings

Across all models, network dimensions contribute significantly to the variance in internal audit quality. Table 8. summarizes the regression coefficients.

Table 8. Regression Results: Network Dimensions Predicting Internal Audit Quality.

Independent Variable	Coefficient (β)	Significance (p-value)	Interpretation
Network Centrality	0.29	p < 0.01	Strong predictor of audit independence
Network Density	0.33	p < 0.01	Enhances risk-based planning & coordination
Coordination Mechanisms	0.41	p < 0.001	Most powerful predictor of reporting quality
Information Exchange	0.27	p < 0.05	Improves audit competence and evidence quality
Relational Trust	0.22	p < 0.05	Strengthens transparency and disclosure
Accountability Structures	0.31	p < 0.01	Improves reporting follow-up
Multi-Level Coordination	0.26	p < 0.05	Enhances methodological consistency

Model Fit: R² = 0.62; Adjusted R² = 0.59 Source: Researcher’s empirical estimation (2024)

5.4.2. Comparative Interpretation Across Countries

Regression strength varies across contexts:

Netherlands & South Korea:

Coordination mechanisms and network density show stronger coefficients.

Reflects mature, integrated oversight systems.

Egypt:

Centrality and information exchange are significant but weaker.

Reflects fragmentation and inconsistent horizontal coordination.

Jordan & Morocco:

Lower explanatory power due to weaker institutional capacity.

5.4.3. Support for Hypotheses

Regression results provide strong support for H1–H7, confirming that:

Network structures significantly shape audit independence, competence, planning, and reporting.

Coordination mechanisms are the strongest overall determinant.

Cross-country context moderates the magnitude, not the direction, of effects.

5.5. Comparative Case-Study Findings

The comparative case-study analysis complements the quantitative results by providing deeper insights into how institutional, cultural, and regulatory differences influence the relationship between network-governance structures and internal audit quality. The cases selected—Netherlands, South Korea, Egypt, Jordan, and Morocco—represent varying levels of institutional maturity, centralization, and procurement system modernization. Examining these variations enhances understanding of the contextual mechanisms highlighted in Hypotheses H5–H7

[63, 66]

5.5.1. Netherlands: High-Density Governance and Integrated Oversight

The Netherlands demonstrates a high-density governance network supported by advanced digital procurement systems and strong institutional coordination. Audit committees operate across ministries, and procurement data are integrated into a single national platform. Interviews reveal that auditors regularly participate in inter-agency learning forums, improving competence and methodological consistency

[46]

. High trust levels among actors further enhance evidence quality.

Key observation:

Network density and coordination mechanisms produce exceptionally high audit-quality outcomes.

This case strongly supports H2, H3, and H7.

5.5.2. South Korea: Technological Integration and Strong Accountability Structures

South Korea’s e-procurement system (KONEPS) provides real-time data-sharing across procurement actors, enabling audit teams to detect anomalies rapidly. Accountability structures are formalized through cross-level audit committees and mandatory reporting standards

[89]

. Information exchange appears as the strongest driver of audit competence and reporting accuracy.

Key observation:

Technologically driven information flows amplify network effects on audit quality.

Clear support for H4 and H6.

5.5.3. Egypt: Fragmentation, Sectoral Silos, and Moderate Network Centrality

Egypt’s procurement network is moderately connected, with pockets of strong oversight but notable fragmentation. Two clusters—financial procurement and service-sector entities—operate in relative isolation. Central actors (e.g., Ministry of Finance audit units) exert influence, but coordination mechanisms remain underdeveloped. Interviews reveal inconsistent reporting standards and limited horizontal learning.

Key observation:

Network centrality plays a role, but density and coordination gaps weaken audit performance.

Supports H1 and H4, but reveals the moderating effect of institutional maturity.

5.5.4. Jordan and Morocco: Emerging Systems with Weak Integration

Both Jordan and Morocco show low-density networks, fragmented reporting channels, and limited cross-agency coordination. Audit practices vary widely across entities, reflecting low institutional maturity

[34]

. Trust deficits hinder disclosure, weakening evidence quality.

Key observation:

Network effects exist but are significantly weaker due to institutional fragmentation.

Partial support for H2–H7, moderated by context.

5.6. Interpretation of Cross-Country Patterns

The cross-country findings indicate that network-governance effects are universal in direction but variable in magnitude. This confirms the theoretical assumption that while network structures influence audit quality, institutional context determines the strength of the relationship.

5.6.1. Institutional Maturity Strengthens Network Effects

In mature procurement systems (Netherlands, South Korea), dense networks and strong coordination mechanisms significantly enhance internal audit quality. This aligns with network governance theory, which predicts stronger outcomes in well-structured networks

[2, 3]

5.6.2. Fragmentation Weakens Audit Outcomes

Emerging systems (Egypt, Jordan, Morocco) exhibit weaker effects due to:

1) siloed procurement structures,

2) inconsistent oversight mechanisms,

3) limited cross-agency trust, and

4) variability in reporting and audit methodology.

These contextual barriers reduce the effectiveness of network-based mechanisms, confirming the moderating hypotheses developed in Chapter 3.

5.6.3. Technology Enhances Information Exchange

Countries with integrated procurement platforms (e.g., Korea’s KONEPS) see stronger effects of information exchange on audit competence and planning

[46]

. Digital integration amplifies network benefits.

5.6.4. Cultural Norms Shape Coordination and Trust

Administrative culture strongly influences relational trust and willingness to share information. Mature governance cultures exhibit higher trust and weaker hierarchical rigidity, improving audit evidence and reporting quality

[11-13]

5.7. Synthesis of Quantitative and Qualitative Findings

The integration of quantitative network analytics with qualitative comparative evidence yields a more comprehensive understanding of how governance networks shape internal audit quality in public procurement. This mixed-method triangulation validates the theoretical model developed in Chapter 3 and provides a nuanced view of the relational mechanisms driving audit performance.

5.7.1. Convergence of Quantitative and Qualitative Insights

Across all countries, quantitative findings demonstrate that:

1) Coordination mechanisms are the strongest predictors of reporting quality (β = 0.41).

2) Network density and information exchange significantly influence risk-based planning and audit competence.

3) Centrality enhances independence and strategic audit influence.

These results are strongly corroborated by qualitative case evidence.

For example:

1) In the Netherlands, high-density networks support consistent audit methodologies—confirming H2 and H7.

2) In South Korea, digital procurement integration strengthens information flows—supporting H4 and H6.

3) In Egypt, moderate centrality but weak coordination leads to mixed audit outcomes—confirming H1 but revealing institutional constraints.

4) In Jordan and Morocco, fragmented networks weaken all relationships—highlighting the moderating role of institutional maturity.

Thus, the triangulation reinforces the idea that network effects are universal but context-dependent.

5.7.2. Divergences and Contextual Nuances

Despite convergence, several divergences emerged:

1) Relational trust (H5) shows strong qualitative support but moderate quantitative coefficients, suggesting that trust may operate more subtly and be difficult to capture with numeric scales.

2) Multi-level coordination (H7) appears stronger in qualitative patterns, especially in countries with structured oversight hierarchies (e.g., Korea), indicating that top-down coordination matters more than quantitative indicators alone suggest.

3) Accountability structures (H6) exhibit strong impact only in countries with institutionalized audit committees.

These nuances validate the use of mixed methods and highlight the importance of institutional context in interpreting network effects.

5.7.3. Implications of Integrated Findings

The synthesis provides three major implications:

1) Internal audit quality is fundamentally relational. Audit outcomes depend not only on internal resources but on the broader governance network in which audit units are embedded.

2) Governance maturity amplifies network benefits. Mature systems convert network density and coordination into stronger audit-quality gains.

3) Fragmentation weakens audit performance. Fragmented networks reduce both information exchange and audit consistency—explaining uneven audit-quality scores in emerging economies.

4) These insights set the stage for Chapter 6, where theoretical, practical, and policy implications will be fully elaborated.

6. Discussion, Implication and Recommendation

6.1. Introduction

This chapter provides an in-depth discussion of the empirical results presented in Chapter 5, assessing how they align with existing literature and with the theoretical foundations described in Chapter 2 and 3. It also evaluates the validity of the hypotheses (H1–H7), analyzes cross-country variations, and articulates theoretical, practical, and policy implications. The aim is to translate the empirical findings into conceptual advancement and actionable insights for strengthening internal audit quality in public procurement systems.

The discussion demonstrates that internal audit quality is a network-embedded phenomenon, shaped by relational structures, information flows, coordination mechanisms, and institutional context. By comparing results across mature and emerging procurement systems, this chapter clarifies how governance networks enable or constrain internal audit functions and how these mechanisms interact with institutional maturity, regulatory strength, and administrative culture

Findings show a significant positive effect of network centrality on audit independence, consistent with previous studies asserting that actors occupying strategic network positions gain enhanced informational power and greater autonomy from managerial pressure

[6, 15, 41, 70

, 76].

This is also aligned with procurement-governance literature that highlights how central nodes exercise greater influence over decision-making

[7-10, 65, 93]

Thus, H1 is strongly validated.

6.2.2. Network Density and Risk-Based Planning (H2)

The study finds that high-density networks improve risk-based audit planning, which aligns with findings that dense procurement systems promote shared risk intelligence and coordinated oversight

[21, 62, 78, 86]

Christensen & Lægreid (2020); Evans & Ferreira (2020); Newman & Clarke (2022) likewise argue that dense relational structures improve coherence and reduce operational silos.

H2 is therefore empirically supported.

6.2.3. Coordination Mechanisms and Reporting Quality (H3)

Coordination mechanisms are the strongest predictor of reporting quality, confirming research showing that structured oversight committees and joint audits enhance follow-up and reporting accuracy

[18, 30, 73]

This is consistent with

[5, 59]

assertion that multi-actor coordination improves accountability in procurement.

H3 receives strong validation.

6.2.4. Information Exchange and Auditor Competence (H4)

The significant effect of information exchange on auditor competence aligns with studies demonstrating that cross-agency learning improves audit methodology and quality

[23, 42, 4, 50]

. Information-sharing systems are known to strengthen detection of procurement anomalies

[46, 52, 69, 87]

Thus, H4 is validated with strong quantitative and qualitative evidence.

6.2.5. Relational Trust and Evidence Quality (H5)

Although quantitative coefficients are moderate, qualitative evidence demonstrates that trust enhances transparency and reduces concealment during audits.

This aligns with some studies

[42, 44, 47, 71]

insights on trust as a facilitator of open communication in audit settings.

H5 is supported but context-dependent.

6.2.6. Accountability Structures and Reporting Integrity (H6)

Findings confirm that stronger accountability structures lead to clearer, timelier audit reporting, consistent with some studies

[17, 62, 77, 82]

H6 is validated.

6.2.7. Multi-Level Coordination and Audit Competence (H7)

The effect of multi-level coordination on auditor competence aligns with literature from

[11-13]

showing that vertically integrated oversight increases standardization.

H7 is strongly supported.

Table 9. Summarizes hypotheses testing results.

Table 9. Summary of Hypotheses Testing Results.

Hypothesis	Empirical Result	Interpretation
H1	Supported	Centrality enhances independence
H2	Supported	Dense networks improve planning
H3	Strongly supported	Coordination is the strongest predictor
H4	Supported	Information exchange improves competence
H5	Moderately supported	Trust improves evidence quality
H6	Supported	Accountability improves reporting
H7	Supported	Multi-level coordination enhances competence

6.3. Alignment of Results With Theoretical Frameworks

The findings of this study not only support the proposed hypotheses but also reinforce and extend three core theoretical perspectives: agency theory, institutional theory, and network governance theory. This section demonstrates how the empirical evidence aligns with and advances each theoretical framework

[68]

6.3.1. Agency Theory Alignment

Agency theory posits that internal auditors act as monitoring agents who reduce information asymmetry and constrain opportunistic behavior by managers in procurement settings

[92]

. The findings validate this theoretical view by showing that:

1) Centrality enhances internal audit independence (H1) by connecting auditors to multiple oversight actors, diluting managerial influence

[16]

2) Accountability structures (H6) strengthen the ability of auditors to enforce compliance, aligning with the agency expectation that monitoring reduces opportunism

[17]

3) Information exchange (H4) helps auditors overcome information asymmetry by accessing richer procurement data.

Thus, empirical evidence demonstrates that network structures mitigate agency risks, confirming and extending the theory into a networked procurement environment.

6.3.2. Institutional Theory Alignment

Institutional theory emphasizes that audit practices are shaped by formal rules, normative pressures, and cultural expectations

[12]

. The study’s cross-country findings reveal:

1) Institutional maturity moderates network effects:

Countries with strong institutions (Netherlands, South Korea) exhibit stronger links between network density, coordination, and audit quality—consistent with the idea that institutional capacity strengthens governance mechanisms.

2) Normative pressures such as professional standards and cultural expectations of transparency encourage higher reporting quality and competence

[24]

3) Coercive pressures (e.g., procurement laws, external audit directives) shape accountability structures (H6), confirming institutional predictions.

Thus, institutional theory is validated as a key lens for understanding cross-country variations in how networks influence audit quality.

6.3.3. Network Governance Theory Alignment

Network governance theory argues that public outcomes emerge from relational interdependence rather than hierarchical control

[2]

. The study strongly supports this view:

1) Network density and coordination mechanisms show the strongest effects on audit quality (H2, H3).

2) Relational trust enhances evidence quality (H5), confirming that trust is a core network governance mechanism

[71]

3) Multi-level coordination (H7) reinforces the argument that governance networks operate across vertical and horizontal layers.

This confirms that audit quality is a network-produced outcome, not merely an organizational attribute.

6.4. Interpretation of Moderating Effects

The analysis in Chapter 5 indicates that institutional maturity, regulatory strength, and administrative culture significantly moderate the relationship between network-governance structures and internal audit quality.

6.4.1. Institutional Maturity

Higher institutional maturity magnifies the positive effects of network density, centrality, and coordination mechanisms on audit quality. Mature systems have predictable procedures, strong oversight culture, and clearer accountability pathways

[63]

Therefore, the same network features yield stronger audit-quality outcomes in Netherlands and South Korea compared to Egypt or Jordan.

6.4.2. Regulatory Strength

Stronger regulatory frameworks enhance the effect of coordination and accountability structures (H3, H6). Countries with clearer procurement laws and enforcement mechanisms exhibit higher reporting quality and compliance rates

[25, 84, 89, 90]

This confirms that regulatory clarity is a catalyst for network-based audit improvement.

6.4.3. Administrative Culture

Cultural norms influence trust, information disclosure, and willingness to collaborate. Mature governance cultures show higher openness, reinforcing H4 and H5. In contrast, hierarchical or risk-averse cultures weaken network benefits by restricting cross-entity communication

[13, 91]

6.5. Theoretical Implications

The findings of this study contribute several significant theoretical advancements to the literature on internal auditing, public procurement governance, and network theory.

6.5.1. Reframing Internal Audit Quality as a Network-Embedded Construct

Traditional audit literature conceptualizes internal audit quality primarily as an organizational outcome shaped by independence, competence, and internal support structures

[23, 52]

However, this study provides compelling evidence that internal audit quality is more accurately understood as a network-embedded construct shaped by:

1) connectivity,

2) inter-organizational coordination,

3) information flows, and

4) relational trust.

This reframes internal auditing within network governance theory, expanding the traditional organization-centric view.

6.5.2. Extending Agency Theory to Multi-Actor Procurement Networks

Agency theory traditionally focuses on dyadic principal–agent relationships. This study extends agency logic into multi-actor procurement networks, demonstrating that:

1) network centrality reduces managerial opportunism;

2) accountability structures operate across multiple actors;

3) information exchange reduces asymmetry not only between managers and auditors but across the entire procurement network.

Thus, agency relationships in procurement must be viewed as multilateral, not bilateral.

6.5.3. Strengthening Institutional Theory Through Moderating Effects

The study shows that institutional maturity and regulatory strength significantly moderate network effects on audit quality. This provides empirical grounding to institutional theory by demonstrating how coercive, normative, and mimetic forces influence the functioning of governance networks.

It also clarifies why network mechanisms succeed in mature systems but underperform in fragmented institutional contexts (e.g., Egypt, Jordan, Morocco).

6.5.4. Developing a Multi-Level Network Governance Model

Findings regarding multi-level coordination (H7) demonstrate that governance networks operate simultaneously at:

1) macro-level (national regulatory bodies),

2) meso-level (sectoral procurement authorities),

3) micro-level (agency-level audit units).

This provides a more comprehensive theoretical model of how vertical and horizontal network structures jointly determine audit quality.

6.6. Practical and Managerial Implications

Beyond theoretical contributions, the study offers actionable insights for practitioners, internal audit directors, procurement managers, and regulators.

6.6.1. Enhancing Coordination Mechanisms

Given that coordination has the strongest empirical effect on audit quality, organizations should:

1) institutionalize joint audits,

2) create inter-agency audit committees,

3) standardize reporting templates, and

4) implement shared procurement-monitoring dashboards.

These mechanisms improve consistency and increase responsiveness to procurement risks.

6.6.2. Strengthening Information-Sharing Systems

Audit teams benefit significantly from timely and accessible procurement data. Managers should:

1) integrate digital procurement platforms with internal auditing systems,

2) establish mandatory cross-entity information-sharing protocols,

3) encourage shared audit knowledge libraries.

This aligns with best practices in advanced systems such as the Dutch and Korean cases.

6.6.3. Building Auditor Competence Through Network-Based Learning

Competence improves when auditors are embedded in network-based communities of practice. Organizations should:

1) encourage cross-entity training programs,

2) support peer reviews among entities,

3) promote participation in regional audit learning networks.

6.6.4. Reducing Fragmentation in Emerging Governance Systems

Egypt, Jordan, and Morocco would benefit from:

1) reducing procurement silos,

2) integrating procurement databases,

3) establishing centralized oversight hubs,

4) aligning audit methodologies across ministries.

Fragmentation weakens audit independence, competence, and quality.

6.6.5. Leveraging Trust and Transparency

Managers should foster a culture of transparency by:

1) rewarding full disclosure,

2) reducing fear of audit consequences,

3) incorporating trust-building exercises in procurement–audit interactions.

Trust significantly improves evidence reliability and audit openness.

6.7. Policy Implications and Recommendations

The empirical and theoretical insights presented in this study provide a robust foundation for designing targeted policy interventions aimed at strengthening internal audit quality in public procurement systems. These recommendations are particularly relevant for policymakers, oversight regulators, audit committees, and ministries responsible for procurement governance.

6.7.1. Strengthening National Coordination Architecture

Given that coordination mechanisms are the strongest predictors of audit quality (β = 0.41), national procurement systems—especially in emerging economies—should institutionalize:

1) Centralized procurement oversight hubs linking ministries, internal audit units, and regulators.

2) National Audit Coordination Councils to harmonize methodologies, terminology, and reporting standards.

3) Inter-ministerial audit committees to ensure cross-sector collaboration.

These structures would create a more cohesive network, reducing duplication and enhancing risk intelligence.

6.7.2. Enhancing Digital Procurement Integration

Data-driven procurement oversight improves audit competence and reporting quality. National governments should:

1) integrate internal audit modules into digital procurement platforms;

2) provide real-time access to procurement metadata, contract histories, and supplier risk profiles;

3) deploy AI-supported alert systems for anomaly detection.

This is consistent with best practices in South Korea’s KONEPS and EU-wide procurement monitoring systems.

6.7.3. Establishing Trust-Building Mechanisms

Trust improves evidence quality (H5). Policy actions include:

1) legally protecting whistleblowers and staff who disclose procurement irregularities;

2) requiring transparent audit dialogues between entities;

3) adopting confidentiality safeguards during preliminary audit stages.

Such mechanisms encourage open communication and reduce concealment behaviors.

6.7.4. Professionalizing Internal Audit Functions

Governments should mandate:

1) standardized competency frameworks for procurement auditors,

2) continuous professional development in network analytics and digital auditing tools,

3) cross-entity auditor secondments for capacity building.

This supports H4 and H7, ensuring competence through network-based learning.

6.7.5. Reducing System Fragmentation

Fragmented procurement networks undermine audit quality. Policy priorities include:

1) integrating sectoral procurement systems into a national platform,

2) aligning procurement regulations across ministries,

3) strengthening the role of national regulatory authorities in enforcing uniform audit standards.

These reforms would significantly enhance network density and coordination.

Table 10. presents Policy Recommendation.

6.8. Social and Economic Implications

The impact of strengthening internal audit quality extends beyond procurement oversight to broader societal and economic outcomes.

6.8.1. Social Implications

1) Increased Public Trust:

Transparent and high-quality audits reduce suspicions of favoritism or corruption, improving citizens’ trust in government institutions

[53]

2) Better Service Delivery:

Effective audit oversight ensures that procurement outcomes—schools, hospitals, roads—are delivered efficiently and ethically.

3) Equity and Inclusion:

Strengthening audit systems reduces elite capture and ensures fair competition among suppliers, fostering inclusive economic participation.

6.8.2. Economic Implications

1) Reduced Procurement Waste and Fraud:

Better coordination and information-sharing reduce leakages, saving millions in public funds,

[25, 84, 89, 90]

2) Enhanced Fiscal Discipline:

Transparent audit practices support budget stability and improve fiscal forecasting.

3) Investor Confidence:

National procurement systems with strong audit quality attract foreign investment, as investors regard such environments as lower-risk.

Efficient Resource Allocation:

Improved audit quality ensures that public resources are allocated where they have the highest development impact.

7. Conclusion and Future Research Directions

7.1. Conclusion

This study set out to examine how network-governance structures influence internal audit quality in public procurement systems through a comparative, mixed-methods approach. Drawing on empirical evidence from Egypt, the Netherlands, South Korea, Jordan, and Morocco, the findings confirm that internal audit quality is not merely an organizational characteristic but a network-embedded governance outcome. Specifically, internal audit quality is shaped by the structural properties of procurement networks—centrality, density, coordination mechanisms, information exchange, relational trust, accountability structures, and multi-level coordination

[80]

The results strongly validate all seven hypotheses (H1–H7), demonstrating that governance-network features significantly affect the four audit-quality dimensions: independence, competence, risk-based planning, and reporting quality. Notably, coordination mechanisms emerge as the strongest determinant of audit quality, followed by network density and accountability structures. These findings align with network governance theory

[2]

, which emphasizes relational interdependence as the primary source of public-sector performance.

The study also extends agency theory and institutional theory. Network centrality reduces information asymmetry and constrains managerial opportunism, deepening the theoretical reach of agency logic in multi-actor procurement environments

[15]

. Institutional maturity and regulatory strength moderate network–audit relationships, empirically substantiating institutional theory’s claim that governance outcomes depend on coercive, normative, and cultural pressures

[11]

. Overall, the study advances a multi-level governance model in which audit quality emerges from interactions between actors at national, sectoral, and organizational levels.

From a practical perspective, the results demonstrate that improving internal audit quality requires strengthening coordination architectures, enhancing digital procurement integration, reducing systemic fragmentation, and fostering trust-based audit environments. Mature procurement systems such as the Netherlands and South Korea demonstrate that dense networks, integrated digital platforms, and strong accountability structures yield highly consistent, transparent, and methodologically sound internal audit practices. By contrast, emerging systems such as Egypt, Jordan, and Morocco exhibit fragmented oversight structures that weaken the benefits of network governance.

Accordingly, policymakers should prioritize reforms that:

(1) institutionalize inter-ministerial audit committees;

(2) integrate real-time procurement data with internal audit systems;

(3) harmonize audit methodologies across government entities; and

(4) strengthen legal protections that promote transparency and trust.

Ultimately, the conclusion recognizes that internal audit quality can only be fully understood within the wider governance network—a paradigm shift with profound implications for audit scholarship, procurement reform, and anti-corruption initiatives.

7.2. Future Research Directions

The study opens several avenues for future research:

1. Dynamic (Longitudinal) Network Analysis

Future studies should examine how procurement networks evolve over time, particularly following major reforms or digital transformations. Longitudinal network modeling would reveal how structural shifts affect audit quality trajectories

[71]

2. Integration of AI and Predictive Analytics

As procurement systems adopt AI-based monitoring tools, future research could explore how algorithmic decision-making influences audit evidence quality, risk detection, and auditor judgment

[46, 81]

3. Micro-Level Behavioral Studies

Qualitative studies exploring how individual auditors navigate trust, independence pressures, and information asymmetry within networks would deepen interpretive understanding

[71]

4. Expansion to Additional Country Clusters

Including additional African, Latin American, or OECD countries would enhance generalizability and clarify how cultural norms moderate network–audit relationships

[63]

5. Network Interventions and Experimental Designs

Future research may test the causal impact of specific interventions—such as building digital procurement hubs or creating cross-agency audit committees—using quasi-experimental designs.

6. Supplier–Auditor Network Effects

Emerging literature suggests suppliers themselves form part of procurement oversight networks. Understanding how supplier data-sharing affects audit quality would extend the model

[89]

7. Cybersecurity and Network Resilience

As procurement networks become digitalized, research must examine how network vulnerabilities, cyber risks, and digital trust influence audit functions
