Abstract: Based on the unbalanced panel data of 113 commercial banks in China from 2009 to 2017, this paper employs the SYS-GMM method to study the impact of financial industry openness on the profits and risks of China's commercial banks. The results show that the opening of the financial industry has increased the competitiveness of the banking industry and reduced the profit margins of banks. Moreover, the non-state banks and non-listed banks are more affected in their profit margins; small banks are more susceptible to the opening of financial industry than large banks. The opening of financial industry has increased bank risks, and the higher the bank's profit margin, the heavier the risk burden will be. Further research also finds out that the higher the degree of competition in deposits, the more mature the market, the smaller the impact of the opening of financial industry on bank profit and risks. Therefore, during the process of promoting the opening of financial industry, it is necessary to focus on the steady operation of the small banks, strengthen the supervision of the banking industry, prevent excessive risk taking of the baking industry caused by competition, and continue to improve interest rate liberalization.

Key words: opening of financial industry, bank profit, bank risks
