摘要
文章运用SEDEA模型和基于DEA的Malmquist生产率指数,对2005—2010年我国22家证券公司的生产效率进行动态研究,并运用效率持续性指数进行聚类分析。结论表明:我国证券业整体生产效率水平不高,且多数证券公司效率持续性较弱;证券公司生产效率的提升主要来源于技术进步,规模对其并无显著影响;证券公司的生产效率过分依赖证券市场行情的情况稍有改善;创新类证券公司在创新评审结束后,生产效率反而低于非创新类证券公司。
Based on the Super Efficiency Data Envelop Analysis （SEDEA） Model and Malmquist index, this paper studies the productive efficiency of 22 securities companies of china from 2005 to 2010 dynamically, and analyses their categories with the method of efficiency sustainability index. It shows that the productivity efficiency of the securities industry is low, and most securities companies＂ efficiency sustainability is weak. Meanwhile, the improvement of the productivity efficiency relies on technical progress, and the scale has no effect on the improvement. However, the situation that the productivity efficiency of the securities companies depends mostly on the market is changing. It also points out that the productivity efficiency of the innovative securities companies is lower than the others after the evaluation of innovation.
