中文摘要：

本文在考虑各国商业银行环境差异的基础上，采用随机前沿分析法（SFA）对我国14家主要商业银行与全球资产规模较大的100家商业银行的效率水平进行测度、比较，结果显示：2001-2007年期间，我国14家主要商业银行效率的平均水平一直低于国外100家商业银行的平均水平；而2008年以来，国内商业银行效率平均水平已经接近并开始超出国外商业银行。就此，本文深入分析了导致效率差异及其变化的原因，结论是，国内外商业银行间效率差异发生的变化，主要与2008以来我国商业银行业务结构改善、盈利能力与资产管理质量提高以及较好的经济增长态势等因素有关。

英文摘要：

This paper measures the efficiency of China＇ s 14 major commercial banks and compares them with top 100 banks across the world by the model of SFA taking commercial environment differences into account. The result shows that the mean values of efficiency of China＇ s banks are lower than those top 100 commercial banks during 2001 - 2007, while come close or even outstand them since 2008. The paper further analyzes the factors that lead to efficiency differences between domestic and foreign banks and the turnover. The turnover is mainly due to the improvement of business structure, profitability and assets management quality, as well as stronger economic growth.
