中国公路经营业动态效率分析——基于Malmquist生产力指数

Dynamic Efficiency Analysis on Highway Industry Based on Malmquist Index

运用基于非参数DEA的Malmquist生产力指数,对中国公路经营类上市公司在2003-2007年间的全要素生产率进行分析的结果表明,该期间中国公路经营业的生产效率波动较大,效率的增长较大程度上得益于技术效率的提高而非技术的进步。说明中国公路经营企业在不断通过规模扩张提高规模效率和经营管理水平的同时,也要进一步加强对技术进步的重视,充分发挥技术进步对生产率的带动作用。

The Malmquist index of total factor productivity was applied to a sample analysis of seventeen China highway operation com- panies over the period of 2003 - 2007. The results showed that the average TFP fluctuated greatly during this period, and the productivity increasing come from the improvement of technical efficiency more than from the technology progress. In view of this situation, technology progress should be paid more attention to so as to give more contribution toward the productivity growth.
