金融科技发展对中小商业银行风险承担的影响研究——基于多重中介效应的机制检验

Research on the Impact of Fin-Tech Development on the Risk-Taking of Small and Medium-Sized Commercial Banks——A Mechanism Test Based on Multiple Mediating Effects

鉴于金融科技发展赋能银行新业态及中小商业银行在地方金融稳定中的重要作用,论文利用2008-2020年178家中小商业银行的微观数据,对金融科技发展与中小商业银行风险承担之间的关系进行实证研究。研究表明:第一,中小商业银行发展金融科技有利于降低其风险承担水平。第二,市场势力和信贷结构作为影响金融科技与中小商业银行风险承担的作用机制,发挥着部分中介效应。其中,提高市场势力对降低风险承担水平的相对贡献度为50.77%,增加信用贷款占比对降低风险承担水平的相对贡献度为24.53%。第三,政府干预力度强弱对金融科技与中小商业银行风险承担的关系具有明显异质性。在强政府干预地区,金融科技对中小商业银行风险承担的影响不显著;而在弱政府干预地区,金融科技能显著降低中小商业银行风险承担水平。

Given the development of Fin-Tech to empower the new banking industry and the important role of small and medium-sized commercial banks in maintaining local financial stability,this paper conducts an empirical study on the relationship between Fin-Tech development and risk-taking of small and medium-sized commercial banks using micro data of 178 small and medium-sized commercial banks from 2008 to 2020.The findings show that:Firstly,the development of Fin-Tech in small and medium-sized commercial banks is beneficial to reduce their risk-taking level.Secondly,market power and credit structure,as the mechanisms that affect the role of Fin-Tech and risk-taking of small and medium-sized commercial banks,play part of the mediating effects.Among them,the relative contribution of increasing market power to reducing the risk-taking level is 50.77%,and the relative contribution of increasing the proportion of credit loans to reducing the risktaking level is 24.53%.Thirdly,there is significant heterogeneity in the relationship between the strength of government intervention and the risk-taking of Fin-Tech and small and medium-sized commercial banks.In areas with strong government intervention,the effect of Fin-Tech on risk-taking of small and medium-sized commercial banks is not significant;while in areas with weak government intervention,Fin-Tech significantly reduces the level of risk-taking of small and medium-sized commercial banks.
