DEA在效率分析领域具有良好的应用，随着全球气候的不断恶劣和环境的逐渐破坏，公众环保意识不断增强，在进行相关效率研究时，非期望产出越来越受到重视。以非期望产出为主要研究点，根据社会对非期望产出指标的认识规律将环保意识分为五个不同阶段，并综合考虑每个意识阶段的特征，将环境指标变动能力，环境承载能力、环境负外部性参与度、外部环境政策管理及企业生产要求纳入DEA效率分析过程中，通过对目标函数和约束条件进行不同的改进和约束，构建了不同意识阶段的DEA效率分析模型，并探讨了各阶段模型的使用范围和相互关系。最后，选取一个实例进行试算，证明各DEA模型的可行性和有效性。

The DEA model has been applied popularly to the field of the efficiency analysis .With the deteriora-tion of the global climate and the destruction of the environment , public environmental awareness continues ris-ing.As a result, the undesirable outputs tend to receiving more and more attention .For detailed analysis of the efficiency analysis in each case , the environmental awareness is divided into five different stages based on the law of cognition of the undesirable outputs .Given the main manifestations of each stage division , environment indica-tor changing capacity , environmental carrying capacity , environmental negative externalities , environmental poli-cy management and enterprise production requirements are combined with efficiency analysis process respectively by adding constrains into traditional DEA models and improving the objective function of DEA models under dif -ferent environmental awareness perspectives .Afterwards, the application range and the relationships between models are discussed .Finally, an example is chosen to illustrate the feasibility and effectiveness of DEA models .
