1990～2007年中国矿产资源型城市全要素生产率的动态实证分析

A Dynamic Empirical Analysis on Total Factor Productivity Change of the Mineral Resource-based Cities in China

运用基于DEA的Malmquist指数法研究了1990～2007年我国50个地级以上资源型城市全要素生产率的变动状况,并将其分解为技术效率和技术进步,发现在此期间,我国资源型城市的全要素生产率略有增长,平均增长率为0.8%,其增长主要得益于技术效率的提高。在此基础上,论文对不同区域、不同类别的矿产资源城市进行了比较,发现其全要素生产率由于技术水平的不同而存在明显差异。

By researching the total factor productivity changes of 50 resource-based cities above the prefectural level from 1990 to 2007 using the DEA-Malmquist index method,we find that total factor productivity increased slightly in this period,with an average growth of 0.8%,mainly because of the improvement in technical efficiency.On this basis,through comparative analysis,we also find that there exists significant difference in the total factor productivity in different regions and different categories of resources,due to technical differences,and that the total factor productivity and the decompositions are lower in those resource-based cities due to technological backwardness.
