摘　　要：使用2011—2022年商业银行非平衡面板数据,构建动态SYS-GMM模型与DID模型探讨存款保险制度对商业银行风险承担的影响。研究结果表明:建立存款保险制度可能诱发道德风险,总体上显著提高了国内商业银行风险承担水平,且由该制度引起的商业银行风险承担水平的变化具有先升后降的区间特征;存款保险制度引起的商业银行风险承担水平的变化与商业银行资产规模和产权属性等异质性特征有关,表现为存款保险制度诱发的道德风险在资产规模较小的商业银行与非国有商业银行中更为显著;存款保险制度主要通过利差收入机制、表外业务机制、存贷比机制与杠杆率机制激励商业银行从事高风险类资产业务,且存贷比机制和杠杆率机制具有更为明显的传导效果。Using the unbalanced panel data of commercial banks from 2010 to 2022,this paper constructs a dynamic SYS-GMM model and a DID model to explore the impact of the deposit insurance system on the risk-taking of commercial banks.The results show that the establishment of the deposit insurance system may induce moral hazard and significantly increase the risk-taking level of domestic commercial banks.Moreover,the change in the risk-taking level of commercial banks caused by this system has an interval characteristic of rising first and then falling.The change in the risk-taking level of commercial banks caused by the deposit insurance system is related to the heterogeneous characteristics such as asset scale and property rights attributes.The moral hazard induced by the deposit insurance system is more significant in commercial banks with a relatively small asset scale and non-state-owned commercial banks.The deposit insurance system encourages commercial banks to engage in high-risk asset business mainly through mechanisms such as interest margin income,off-balance-sheet business,loan-to-deposit ratio,and leverage ratio.Among them,loan-to-deposit ratio mechanism and leverage ratio mechanism have more obvious transmission effects.
