环境效率评价中DEA模型的发展研究

Study on Development of DEA Model in Environmental Efficiency Evaluation

资源短缺和环境污染问题是制约我国经济发展的两大"瓶颈",建立资源节约型和环境友好型社会是我国一个基本国策。解决这两个问题首先要建立一个科学的评价体系,环境效率评价体系是现在被广泛接受的科学评价体系。数据包络分析是一种用来分析评价比较不同决策单元间效率的数学方法,而且在环境效率评价体系中地位也越来越重要。总结了环境效率评价中应用的数据包络分析方法,分别从DEA模型方法与其他方法结合的横向方面和DEA模型方法中指标选取、外部因素、决策单元内部复杂性、污染物排放及其分配等纵向方面去分类综述,最后指出在环境效率评价方面未来DEA方法研究的可能方向。

Lack of resources and environmental pollution are two major problems restricting the e Gonomic development of China, and building resource-conserving and environment-friendly society is a basic national policy in China. To solve these problems the first step is to set up a sci entitle evaluation system, environmental efficiency evaluation system is now widely accepted scientific evaluation system. Data envelopment anal ysis （DEA） is a kind of mathematical method used for compare different decision-making unit efficiency. It acted an important role in the envi ronmental efficiency evaluation system. The application of data envelopment analysis （DEA） method in environmental efficiency evaluation sys tem was summarized. In lateral aspect compare the DEA model method and other methods. And in longitudinal aspect introduce the process i~ method like the index selection, external factors, internal complexity of decision making units and pollution emission. At last we point out the di rection of DEA method in environmental efficiency evaluation research in the future.
