为了分析电网行业的生产率受技术进步和技术效率的影响程度，使用基于DEA的Malmquist生产率指数方法，以9家省电力公司为样本，对电网企业的技术和生产效率的动态变动情况进行了研究。结果表明，2005—2010年间样本电网企业的全要素生产率年平均增长率为3．2％，技术进步的贡献大于技术效率的贡献。技术效率指数表现不优是由于多数样本企业的实际规模与最佳规模之间的偏差较大。因此为了提高我国电网企业生产率，关键是提升效率特别是规模效率。

In order to conduct an empirical analysis of the technical progress and technical efficiency＇ s influence on total factor productivity im-provement in Chinese Grid Enterprises, the Malmquist productivity index is calculated by means of Data Envelopment Analysis （DEA） by using 9provincial electricity distribution companies＇ data. The result shows that for the period of 2005 2010, the total factor productivity index of thesample companies increases with 3.2% average growth rate, in which technical progress plays a greater part than technical efficiency change. Thepoor performance of technical efficiency is mainly caused by the gap between real scale and best scale of the sample companies. Therefore, the keyto increase the productivity of Chinese grid enterprise is to improve technical efficiency especially the scale efficiency.
