银行竞争、银行创新与银行风险承担

Competition,Innovation and Risk-Taking of Banks

在银行通过传统信贷业务应对银行业竞争受阻的背景下,采用2002—2016年上市银行的微观面板数据,使用系统GMM方法测度了银行竞争对银行风险承担水平的影响及其作用渠道。实证结果表明:银行竞争显著增加了银行风险承担水平,抑制了银行的创新行为,而银行创新对商业银行风险承担的影响以风险分散为主,从而增强了银行竞争度与银行风险的正向关系。因此,银行应积极开展多元化竞争策略,进行业务升级转型;监管部门要有序引导银行业竞争,制定适度的监管规则,防范因过度竞争导致创新度下降的风险叠加效应。

In the context of the hindrance to coping with banking competition through traditional credit business,this paper employs the micro panel data of listed banks in China during 2002-2016 and System GMM estimation in its analysis of the impact of competition on bank’s risk-taking and its influence mechanism. The results show that bank competition significantly raises risk-taking of banks and restrains innovation,which in turn heightens the positive relationship between competition and risks as innovation mainly impacts risktaking of commercial banks through risk dispersion. Therefore,the banking sector should actively diversify its competitive strategies and carry out business upgrading transformation while regulators should guide the banking industry in an orderly manner and set proper regulatory rules as a prevention of risk superposition from drop of innovation brought about by excessive competition.
