经济政策不确定性对中国银行业经营效率影响研究

Research on the Impact of Economic Policy Uncertainty on the Operating Efficiency of the Banking Industry in China

立足于中国经济政策不确定性和银行业经营的实际情况,分析经济政策不确定性对中国银行业经营效率的影响。研究结果显示,经济政策的不确定性会降低银行经营效率,且影响程度会随时间变化而降低,该结论经过一系列稳健性检验后仍然成立;经济政策不确定性通过银行风险承担和银行利息净收入两个影响机制对银行经营效率产生作用;经济政策不确定性对银行经营效率的影响在不同类型银行之间存在异质性;金融科技发展可以缓解经济政策不确定性对银行经营效率的负面影响。

Based on the economic policy uncertainty in China and the actual situation of banking industry operation,this article analyzes the impact of economic policy uncertainty on the operational efficiency of China's banking industry.The research results show that economic policy uncertainty reduces the operational efficiency of banks,and the impact decreases over time.This conclusion still holds after a series of robustness tests.Economic policy uncertainty affects the operational efficiency of banks through two mechanisms:risk-taking and net interest income of banks.The impact of economic policy uncertainty on the operational efficiency of banks varies among different types of banks.The development of financial technology can alleviate the negative impact of economic policy uncertainty on the operational efficiency of banks.
