RESEARCH ON REGIONAL ECO-EFFICIENCY OF CHINA FROM 2000 TO 2006——AN EMPIRICAL ANALYSIS BASED ON DEA
运用DEA方法测度2000-2006年中国区域生态效率，发现全国整体效率变化不大但区域差异明显，东部远高于中西部，工业污染物和自然资源是主要影响因素，粗放型增长模式制约效率提升。
Eco-efficiency indicators are used to measure the development level of circular economy,which reflect the efficiency of utilizing natural resources and releasing environment pressure in the development of economic. This essay attempted to apply DEA method to the empirical analysis of eco-efficiency. From a macroscopic point of view,the measure and evaluation were made upon regional eco-efficiency of China from 2000 to 2006. The results show that:①in this period the whole eco-efficiency of China changed little and the values remained about 0.7-0.8,but the difference between areas was obvious. The eco-efficiency values of East,Middle,West regions were 0.939,0.712 and 0.641 respectively. There were significant difference in East region and Middle and West regions. ②Such pollutants as industrial solid wastes,industrial dust,smoke dust and such natural resources as land,water were major factors influencing regional eco-efficiency. ③Generally,the extensive economic growth mode restricts the improvement of regional eco-efficiency,and it is the basic way to improve the eco-efficiency and realize sustainable development that promotes the transformation from the extensive growth to intensive growth.
