1998-2003城市生产效率:基于包络技术的实证研究

Productivity in Urban Area through 1998-2003:an Empirical Study Based on DEA

本文利用包络技术估算我国1998—2003年216个城市的Malmqu ist生产力指数和规模报酬状态,对扩张时期城市生产效率进行实证研究。得出两个主要结论:一是我国城市全要素生产率显著改善,表明城市总体在良性轨迹上发展;二是我国部分大城市缺乏规模效率,投入—产出比例失衡;部分中小城市技术效率不足,要素使用效率低下。因此合理化要素配置和提高要素使用效率是我国城市未来发展的关键。

This paper uses DEA to empirically study urban Malmquist index and scale return with 216 city data through 1998-2003.We have two major conclusions.Firstly,the overall productivity in China cities has improved significantly and the overall situation is on the healthy track of development.Secondly,some large cities lack scale efficiency and have improper inputoutput ratio;some middle and small cities lack technological efficiency and especially have low production factor employment.Thus the key to China urban development is to optimize production factor distribution and improve productivity.
