| 摘 要： | 文章给出了已有文献对环境效率度量的6种DEA(数据包络分析)模型,比较了它们各自对非期望产出处理的特性和缺陷,并以安徽43家企业为例,对其度量结果存在的差异进行了分析和解释.度量结果显示,只有基于松弛测度的SBM模型对企业环境效率的差异识别性较强.

| Abstract: | Six DEA(Data Envelopment Analysis) models are introduced in the environmental efficiency measure literature.After comparing the characteristics and defects of dealing with undesirable output,using 43 enterprises′ data in Anhui Province,we analyze and explain the difference among the results.Measurement results show that only the slacks-based measure(SBM) model can distinguish differences from each other in environmental efficiency measurement. |

| Keywords: | environmental efficiency undesirable output DEA SBM model directional distance function |
