摘　　要：本文使用勒纳指数衡量银行竞争程度,基于56家商业银行2010—2019年的动态面板数据,实证分析银行竞争对货币政策银行风险承担渠道的影响。为进一步探究这种影响是否因银行类别和竞争程度不同而存在差异,将样本分别按照银行类型和竞争程度高低分组进行回归分析。研究结果显示:宽松的货币政策激励银行承担更多的风险;银行的竞争程度越高,资产规模越小,流动性水平和资本充足率越低,货币政策对其风险承担的影响越强;竞争加剧对这种影响的强化作用,主要体现在股份制银行和城农商行中;对于竞争程度较高的银行而言,流动性水平和资产充足率越高,对宽松货币政策的反应越审慎。This paper uses the Lerner index to measure the degree of bank competition,and empirically analyzes the impact of bank competition on the bank risk-taking channel of monetary policy based on the dynamic panel data of 56 commercial banks in China from 2010 to 2019.To further investigate whether the impact differs by the bank type and the competition degree,the samples are divided into high and low groups for regression analysis.It is found that the loose monetary policy encourages banks to take greater risks,and the negative impact of monetary policy on bank risk-taking tends to enhance with the increase of bank competition,the reduction of asset scale,the decline of liquidity,and the reduction of capital adequacy ratios.Additionally,the intensification of bank competition strengthens this negative impact,which is mainly reflected in joint-stock banks,urban commercial banks,and rural commercial banks;for banks with a higher level of competition,the higher the level of liquidity and the asset adequacy ratio,the more cautious the reaction to the loose monetary policy.
