商业银行金融创新、资本缓冲与风险承担

Financial Innovation,Capital Buffer&Risk-taking of Commercial Banks

商业银行作为金融系统的核心,其风险承担能力是防范化解系统性金融风险的重要保障。以2007年至2018年沪深A股上市商业银行为样本,通过中介效应分析法,实证研究了商业银行金融创新、资本缓冲和风险承担三者之间的关系。研究发现:1.金融创新降低了商业银行的资本缓冲,增加了商业银行的风险承担。2.资本缓冲在金融创新对商业银行的风险承担影响中发挥了显著的中介作用。3.董事会中专业委员会的治理发挥了对资本缓冲中介效应的调节作用,有助于降低商业银行风险承担。

As the core of the financial system,the risk-taking capacity of commercial banks is an important guarantee to prevent and resolve systemic financial risks.Based on the sample of listed commercial banks from 2007 to 2018,this paper empirically studies the relationship among the financial innovation,capital buffer and risk-taking of commercial banks with the method of intermediary effect.Findings are:1.Financial innovation reduces the capital buffer of commercial banks and increases the risk of commercial banks;2.Capital buffer plays a significant intermediary role in the impact of financial innovation on the risk-taking level of commercial banks;3.The governance of professional committee in the board of directors plays a regulatory role in the intermediary effect of capital buffer,which helps to reduce the risk-taking of commercial banks.
