摘　　要：文章利用Fried et al(2002)提出的三阶段DEA模型对2009年我国44家综合型证券公司的效率水平进行了实证分析。研究表明,证券公司的效率水平的确受到环境变量的影响,在排除环境变量影响后的同质经营环境下技术效率水平明显下降,而且效率损失主要来源于规模无效。提高金融服务手段创新、扩大市场占有率、引进战略投资者、实施兼并重组加快上市步伐是提升证券公司效率的重要途径。The paper evaluates technical efficiency of 44 comprehensive securities companies of China in 2009 with DEA three-stage model proposed by Fried et al（2002）.The results demonstrate that the technical efficiencies are really affected by environments,after exclusion the environment variables in the homogeneous operating environment the level of technical efficiency significantly decreased and efficiency loss comes mainly from the scale invalid.Improve the financial service innovation,expand its market share,introduction of strategic investors,implementation of merger and step up to market is an important way to enhance the efficiency of securities firms.
