摘要
在DEA窗口分析中引入基于非期望产出的非径向、非角度SBM模型对2006-2011年间我国30个区域的生态效率进行动态的测度和分析。结果表明,在此期间从整体上讲我国的生态效率是进步的,但各个地区的差异较大。生态效率最大的地区在此期间生态效率排名保持前列;生态效率较高的地区其效率变化幅度较大,且效率值是改善的;而生态效率较小的地区其效率变化幅度较小,是波动或者下降的。
Combining method of DEA window analysis and the Slacks - based Measure （SBM） with undesirable outputs, the Regional eco- efficiency of 30 provinces in China are measured and analyzed during 2006 -2011. The results demonstrsate the eco - efficiency of China is improving during the period, however, the eco - efficiency are different each other very much. The efficiency of the provinces with high efficiency shows great change and improvement ; the efficiency of the provinces with high efficiency shows soft change and fluctuation or descent.
