「永續發展」強調的是經濟發展、環境保護及社會公平三個面向均衡發展。而為了因應「永續發展」的潮流，一個工業區的發展，除了應著重於進駐廠商的增加、整體生產規模的提昇外，對於其生產所造成的環境衝擊，以及該工業區與週遭鄰里社區的善意互動，也應漸受重視。 本文依據世界企業永續發展委員會（WBCSD）提出的「生態效益」(eco-efficiency)概念－以更少的資源及污染，提供更高的產品與服務價值；同時兼具增進經濟利益與改善環境品質－來評估一個工業區的環境與經濟績效。主要的研究對象，是彰濱生態化工業區，及其週遭社區/工業區。首先，依據該工業區的生產現況，建構可能的生態化鏈圈；來進行其生態效益比值的試算與分析。之後，依據分析試算所得的結果，規劃出不同情境下之最佳生態化鏈圈。並嘗試建立相關數學模式，來歸納此結果。本文最後的成果，可作為彰濱生態化工業區及相關主管官署，在尋求自身發展與招商時的參考。 另外，在文中所運用的步驟、試算與分析方法，亦可提供給有需要的相關單位，作為他日建構不同之生態化鏈圈時的主要依據。 “Sustainable Development”is a concept that stresses on the balance of economic growth, environmental protection and social equity. And during the stage of economic development,establishment of industrial parks has long been considered as an effective way of achieving the goal of economic growth, for the companies in an industrial park are easy to manage and control. In order to response the trend of sustainable development, however, an industrial park is no longer only for increasing the number of factories and the amount of production, but also being a good neighbor of the community nearby. This paper based on the concept of “eco-efficiency” to evaluate both the economic performance and the environmental performance of an industrial park. The Changhua Coastal Industrial Park (CHCIP) and its vicinity was study to fulfill the goal. An eco-industrial loop, which consisted of 7 companies and centered by a big steel mill, for transforming wastes into constructive materials was first identified. After collecting and analyzing the environmental and economic data for each one of the companies within the loop, the eco-efficiency ratios of the companies and the loop can be evaluated. The eco-efficiency ratios were evaluated based on three situations, they are before the loop formed, after the loop formed, and a future scenario (i.e. zero emissions is achieved).
