Abstract: The rapid development of digital finance promotes the commercial banks to form a new competitive pattern and brings great challenges to the bank's risk control. Based on the panel data of 149 small and medium-sized commercial banks, this paper builds a model to both theoretically discuss and empirically study how digital finance affects the competition and risk-taking of China's small and medium-sized commercial banks. The results of the study are as follows: (1) The development of digital finance promotes the competition among small and medium-sized commercial banks and raises the risk-taking level of small and medium-sized commercial banks; (2) Reduced competition among small and medium-sized commercial banks is conducive to reducing risks caused by digital finance; (3) The development of digital finance has a greater impact on urban commercial banks and small and medium-sized commercial banks in the central and western regions. Therefore, small and medium-sized commercial banks need to prevent and control the risks caused by intensified competition in the industry while at the same time combine their own competitive advantages to formulate transformation and development strategies, so as to enhance their risk control ability in the face of the crisis.

摘要： 高速发展的数字金融推动商业银行形成新竞争格局的同时给银行风险控制带来了巨大挑战。本文采用中国149家中小商业银行的面板数据构建模型,对数字金融如何影响中小商业银行竞争和风险承担进行了理论探讨和实证研究,结论表明:(1)数字金融发展促进了中小商业银行间竞争,提高了中小商业银行风险承担;(2)中小商业银行间竞争减弱有利于降低数字金融引发的风险;(3)数字金融发展对城市商业银行和中西部地区中小商业银行的影响更大。因此,中小商业银行需防控行业竞争加剧带来的风险,同时结合自身竞争优势制定转型发展战略,增强面对危机时的风险控制能力。
