摘　　要：本文采用考虑非期望产出并综合径向和非径向特点的EBM模型和GML指数来测算城市商业银行的静态效率和动态全要素生产率,并实证检验利率市场化对城市商业银行效率的影响。研究结果表明,城市商业银行全要素生产率呈现增长趋势,技术效率有所改善但却幅度不大,技术进步一直是城市商业银行全要素生产率提高的关键因素。利率市场化及其引致的价格竞争效应会通过降低净资产收益率和加大不良贷款风险的方式不利于银行综合效率和全要素生产率的提高,而银行自有资本比率和资本充足率的上升却有利于化解不良贷款风险而有利于提高银行效率。This paper adopts the EBM model which considers the non expected outputs and integrates radial and non radial characteristics and the GML index to calculate the static efficiency and dynamic total factor productivity, and then make an empirical test on the impact of interest rate liberalization on the efficiency of the city commercial banks. The research results show that, the total factor producti of city commercial banks increases, and the technical efficiency has improved but modest, vity and technical progress is always the key factors of Improving total factor productivity of city commercial banks. The effect of price competition caused by interest rate liberalization is not conducive to improving the comprehensive efficiency and total factor productivity by the way of reducing the rate of return on net assets and increasing the risk of bad loans, but the rise of the bankg own capital ratio and capital adequacy ratio is conducive to improving the bank efficiency by resolving the non -performing loan risk.
