中文摘要：	上世纪70年代开始，全球兴起了金融自由化改革，我国也于1996年开始进行相关改革，并于2015年基本完成存贷款利率市场化。在利率市场化、市场准入限制放松、互联网金融蓬勃发展的背景下，许多城商行、外资银行甚至是民营银行涌入市场，使得商业银行的竞争加剧，这对于我国银行业的稳步运行造成影响。而银行业的稳健发展是我国金融体系得以持续稳定运行的基础，更有利于我国经济社会的正常运作。因此，为了维护我国经济的稳步发展，有必要研究银行竞争对其风险承担的影响。 本文选取了65家本土商业银行和7家外资银行共72家银行，从2011年到2018年的面板数据进行实证分析。文中以不良贷款率和Z值代表银行风险，勒纳指数代表银行竞争，并计算了HHI指数进行稳健性分析。本文首先对本土65家商业银行竞争与风险之间的关系进行回归，并根据稳健性分析，选取合适的竞争代理变量；然后模拟不同所有制银行加入市场竞争的过程，分别回归，研究其对风险承担的影响；最后探究外资银行加入市场竞争后，是否会对我国银行的风险承担造成影响。 结果发现，我国本土商业银行竞争与信贷风险和经营风险之间都呈U型关系。另外，不同所有制银行加入到市场竞争的过程中，竞争与风险之间的线性项和非线性项都由不显著变为显著，说明在这个过程中，竞争对风险承担的影响程度是在增大的，也说明在现阶段，由于很多中小型银行的存在，仅仅国有银行和股份制银行已经不能代表整个银行业市场。最后，外资银行的加入使竞争与信贷风险的关系变为线性，而竞争与经营风险仍保持非线性关系，这说明，外资银行加入我国银行业市场，对银行的信贷风险影响较大，而对银行经营风险的影响不明显。
英文摘要：	Since the 1970s, financial liberalization reforms have emerged around the world. China has also started to carry out relevant reforms in 1996, and basically completed the marketization of deposit and loan interest rates in 2015. Against the background of interest rate liberalization, market access restrictions relaxation, and the booming Internet finance, many city commercial banks, foreign banks and even private banks have flooded into the market, intensifying the competition of commercial banks, which has affected the steady operation of China's banking industry. The steady development of the banking industry is the basis for the sustainable and stable operation of China's financial system, and it is more conducive to the normal operation of China's economy and society. Therefore, in order to maintain the steady development of China's economy, it is necessary to study the impact of bank competition on its risk-taking. This paper selects a total of 72 banks including 65 local commercial banks and 7 foreign banks, and conducts empirical analysis on panel data from 2011 to 2018. In this paper, the NPL ratio and Z-score represent bank risk, the Lerner index represents bank competition, and the HHI index is calculated for robust analysis. This paper first performs regression analysis on the relationship between competition and risk of 65 local commercial banks, and selects the appropriate competitive agent variable according to the robustness analysis. Then it simulates the process of different ownership banks joining the market competition and regresses separately to study their risk exposure. Finally, it explores whether foreign banks can affect the risk-taking of Chinese banks after joining the market competition. It was found that there is a U-shape relationship between competition and credit risk and operating risk in China's local commercial banks. In addition, when banks with different ownerships participate in the market competition, the linear and non-linear terms between competition and risk change from insignificant to significant, indicating that in this process, the degree of competition’s impact on risk-taking is increasing. It also shows that, at this stage, due to the existence of many small and medium-sized banks, only state-owned banks and joint-stock banks can no longer represent the entire banking market. Finally, the addition of foreign banks has made the relationship between competition and credit risk linear, while the relationship between competition and operating risk remains non-linear. This shows that the participation of foreign banks in China’s banking market has a greater impact on credit risk and has a lower impact on operating risk.
