Abstract:
This study aimed to investigate the effects of corporate governance on audit 
quality. Using a sample of 100 Sri Lankan listed companies from 2016 to 
2020, this study used the ordinary least squares method. The results of this 
study overall suggests that there is a significant relationship between board 
size, board independence, audit committee independence and audit quality 
proxies. However, CEO duality and audit committee financial literacy are 
only significantly associated with BIG4. This study demonstrates the need 
of taking the institutional context into account in governance studies. This 
research focused on companies in Sri Lanka. Future studies should look 
into this issue in other contexts and time periods. This study is significant 
for practitioners and academics, legislators, and professional accounting 
organisations because it demonstrates how legislative reforms might 
encourage corporations in emerging markets to adopt good governance 
practices. The findings are also valuable for investors in examining the 
impact of corporate governance on audit quality. The study adds to the 
body of knowledge by demonstrating that there is a substantial association 
between corporate governance and audit quality in Sri Lankan listed 
companies.
