This study examined the impact of data analytics and artificial intelligence (AI) on audit
quality of listed manufacturing companies in Nigeria. Specifically, the study investigated the
effects of audit data analytics adoption, artificial intelligence utilization, and auditor
technological competence on audit quality. The study was anchored on the Technology
Acceptance Model and Resource-Based View Theory. An ex-post facto research design was
adopted, and data were obtained from annual reports and corporate disclosures of 25 listed
manufacturing companies on the Nigerian Exchange Group (NGX) covering the period
2015–2024. The study employed panel regression analysis. Audit quality was proxied by
audit report quality, while data analytics adoption, AI utilization, and auditor technological
competence served as explanatory variables. The findings revealed that audit data analytics
adoption has a positive and significant effect on audit quality (β = 0.421, p = 0.000),
artificial intelligence utilization exerts a positive and significant effect on audit quality (β =
0.387, p = 0.002), while auditor technological competence also has a positive and significant
influence on audit quality (β = 0.294, p = 0.011). The model explained approximately 68.4%
of the variation in audit quality (Adjusted R² = 0.684). The study concluded that data
analytics and artificial intelligence significantly enhance audit quality by improving audit
efficiency, fraud detection capability, risk assessment accuracy, and financial reporting
reliability. The study recommended increased investment in AI-enabled audit systems,
continuous auditor training, and the establishment of regulatory guidelines for technology
assisted auditing.
