摘　　要：本文运用SBM方向性距离函数和Luenberger生产率指标测度了2003～2009年中国11家上市商业银行不良贷款约束下的效率和全要素生产率增长,并对影响效率和全要素生产率的宏观因素进行了实证分析。研究结果发现:股份制商业银行的效率优于大型商业银行,非利息收入和不良贷款是银行无效率的主要来源;中国银行业的全要素生产率是增长的,股份制商业银行的全要素生产率高于大型商业银行,主要体现在规模效率变化和技术规模变化;外资银行的进入和M_2的供给增长对中国银行业的发展起到推动作用。This paper applies SBM directional distance function and Luenberger productivity indicator to measure the bank efficiency and TFP under the constraint of non-performing loans, and analyzes the influence from macroeconomic factors. The efficiency of joint-stock commercial banks is better than that of large state-owned commercial banks. Non-interest income and non-performing loans are the main sources of inefficiency. The TFP of China＇s banking operates well, and the joint-stock commercial bank is better than the large state-owned commercial bank, attributing to the scale efficiency change and the technology progress scale change. The share of foreign banks and M2 supply growth push China＇s banking ahead.
