碩士 === 國立政治大學 === 會計學系 === 104 === Since 2005, PCAOB has inspected foreign registered audit firms for a period over ten years. The benefits of inspection in both the United States and other countries are documented by extant literature, but the research of country characteristics on the spillover benefits is still lacking. In this study, we document how country characteristics influence the spillover effect of PCAOB international inspection on audit quality. This study uses discretionary accruals as the proxy of audit quality. Our data of non-US-listed companies from 35 countries during 2004-2013 are taken from Datastream. In addition, we use legal enforcement and Big 4 dominance to investigate how country characteristics affect the magnitude of audit quality changes. According to empirical results, we find that countries with higher legal enforcement or Big 4 dominance provide better audit quality. Therefore, PCAOB international inspections in these countries generate smaller magnitude of audit quality improvement than in countries with lower legal enforcement and Big 4 dominance . Our results suggest that regulators of different countries should develop more tailored regulation in order to improve audit quality of their respective countries.
