摘　　要：通过三阶段DEA方法对我国57家商业银行在2004-2017年期间经营效率进行了测度,并进一步构造函数测度了利率市场化改革进程,通过固定效应模型探究利率市场化改革与我国银行业经营效率间的关系,实证结果表明:利率市场化改革与我国商业银行经营效率之间存在倒U型关系;利率市场化有利于改善商业银行的规模效率却不利于其纯技术效率的提高;此外,利率市场化改革对规模较小的商业银行影响更大。This paper measures the operating efficiency of 57 commercial banks in China during the period of 2004-2017 by using the three-stage DEA method, and further constructs the function to measure interest rate liberalization referred to IRL reform process since the reform and opening up. Through the fixed effect model, we explore the impact of IRL reform on the efficiency of China's banking industry. The empirical results show that: There is a inverted U-shaped relationship between the two;The results of the three-stage DEA model show that: The IRL reform is beneficial to improve the scale efficiency of commercial banks, but it is not conducive to the improvement of pure technology efficiency. In addition, the impact of IRL reform has a greater impact on smaller commercial banks.
