| 摘 要： | 期望产出的生产过程通常伴随着对环境造成一定程度破坏的副产品的生成,但经典的DEA模型很难解决考虑非期望产出的效率评价问题。本文给出了一种改进的环境效率评价ISBM-DEA模型,并构造一个算例,将这一改进的模型与环境评价经典模型SBM的评价结果进行对比,结果表明新模型的计算结论和使用SBM得到的效率评价值相关程度很高,而且比SBM模型更加注重非期望产出对生产效率的影响,说明此模型具有更为广泛的应用价值。

| Abstract: | Production process of desirable outputs often produces by-products,which have harmful effects on the environment.However,traditional DEA models cannot measure efficiency evaluation of these undesirable outputs.This paper proposes an improved DEA-SBM model,named ISBM-DEA,and constructs an illustration to compare it with slacks-based measured DEA model.The results show that computing conclusions of the new model are highly related to the efficiency assessment of DEA-SBM model,and that it focuses on the effect... |
