采用当期DEA和序列DEA方法估算1998~2008年中国各省份的Malmquist-Luenberger生产率指数。研究发现:样本区间内我国东、中、西三大区域环境约束下的TFP增长率依次降低,除北京和上海之外,其他省份的经济增长主要依靠要素投入的增加;省级TFP增长率波动较大,2005年以来呈明显的上升趋势,表明我国近年出台的环境政策对于破解环境难题和转变增长方式起到了明显的效果;生产率指数的分布动态反映出生产率增长的省际差异随时间推移趋于扩大。
The current DEA and DEA methods were used to estimate the Malmquist-Luenberger productivity index of Chinese provinces from 1998 to 2008. The results show that the growth rate of TFP under the circumstance of the three major regions of East, Central and Western China in the sample interval decreases in turn, except for Beijing and Shanghai, the economic growth in other provinces mainly depends on the increase of factor inputs; the provincial TFP growth rate fluctuates This shows that the environmental policies introduced in recent years in our country have played a significant effect on solving environmental problems and changing the mode of growth. The dynamic distribution of the index of productivity reflects that the provincial differences in productivity growth tend to increase with time To expand.
