本文擴充Charnes,Cooper及Rhodes[13]之DEA效率評估模式以及 Chang,Hwang及Cheng[12]衡量組織相對效能之模式，提出衡量環境品質的方法， 並以 「自我評估」及「同僚評估」的角度分別評估台灣地區23個行政區域的環 境品質;同時，本文亦延伸Chang et.al.衡量效能變動之模式，成為衡量環境品質變 動之模式「以評估台灣地區23個行政區域在民國79年至81年間環境品質的相對變 動。而經由環境品質及其變動程度的衡量，本文進一步提出環境品質管理之方 向，以提供環保機構進行環境管理時之參考資訊。

　　　　　The purpose of this study is to extend the use of the data envelopment analysis(DEA)approach, developed by Chames, Cooper and Rhodes[13], and the measurement of relative effectiveness, developed by Chang. Hwang and Cheng[12], and which proposes a mathematical programming model for measuring the environmental quality in 23 administrative regions of Taiwan in1992. At the same time, this paper also modifies the model for measuring the effectiveness change of anorganization, proposed by Chang, Hwang and Cheng[12], to become a model for measuring the change of environmental quality, and use the model to determine whether the change of environmental quality of the 23 administrative regions in Taiwan moved forwards or backwards between 1990 and 1992. The model in this paper can be used to measure the relative environmental quality and relative environmental quality, change under multiple criteria, wherein each criterion represents a familiar environmental index. The detailed steps in application are described. The case in this paper also can provide useful information for generating directions for making improvements.
