DETERMINANTS OF AUDIT QUALITY IN UKRAINE: ANALYSIS BASED ON QUALITY CONTROL RESULTS AND MARKET INDICATORS

Abstract

Purpose. The purpose of the article is to investigate the determinants of audit quality in Ukraine based on a combination of theoretical approaches and empirical market data, as well as to identify key factors influencing audit quality in the context of structural transformations in the audit services market. Methods. The methodological framework is based on a combination of institutional, systemic, and analytical approaches. The study employs methods of statistical analysis, comparison, generalization, and economic interpretation of data. The empirical basis includes official reports on the audit services market, reflecting structural characteristics, pricing dynamics, and quality control results. Results. The study reveals that the audit services market in Ukraine is characterized by structural transformation, manifested in increasing service costs, market concentration, and differentiation across client segments. It is established that audit quality varies significantly depending on the category of clients, with the highest quality observed in public interest entities. The analysis confirms a relationship between audit fees and audit quality, reflecting the complexity and depth of audit procedures. A system of key determinants of audit quality is developed, including institutional, market, professional, and organizational factors. Scientific novelty. The scientific novelty lies in the integration of theoretical and empirical approaches to the assessment of audit quality, as well as in the development of a comprehensive system of determinants that reflects the multidimensional nature of audit quality within the context of a transforming market environment. Practical significance. The results of the study can be used to improve regulatory mechanisms in the audit sphere, enhance quality control systems, and support decision-making by stakeholders involved in the audit process. The proposed analytical framework can serve as a basis for further empirical and econometric research. Conclusions. Audit quality is a complex and dynamic economic category formed through the interaction of multiple factors. Its level depends on the balance between regulatory pressure, market incentives, and professional capabilities of auditors. The findings highlight the need for a comprehensive approach to audit quality assessment and provide a foundation for future quantitative research.
