The purpose of this paper is to investigate the relationship between corporate governance and firm performance. In order to examine the relationship, this paper employed panel data regression techniques using stock data to represent the aggregate composition of the Shanghai Stock Exchange 180 Index (SSE 180 index) based on Chinese capital market from 2010 to 2019. The empirical results showed that corporate governance could influence the firm performance. More specifically, both board size and CEO duality are positively and significantly related to firm performance measured by ROA. While board independence has not yet had a significant and positive impact on firm performance. There is no significant relationship between state ownership and firm performance. CEO compensation can indeed improve firm performance. Debt has a significant negative correlation with firm performance. Therefore, the viewpoint that good corporate governance can lead to better firm performance is not true of every country because of the different culture in the different country.
