Abstract

This study examines both economic and environmental performance of an industrial park using the eco-efficiency indicator framework. The case study involves Chang Hua Coastal Industrial Park (CHCIP) and its surrounding area in central Taiwan. An eco-industrial cluster consisting of seven companies and anchoring a large steel mill was identified for recovering of waste generated into construction materials. (It was referred to as being 'eco-industrialization' hereinafter). The eco-efficiency of individual companies and the overall eco-efficiency of the total system were quantified using one economic indicator (after-tax profit) and five environmental indicators (energy consumption, water consumption, raw material consumption, CO2 emission, and total waste generated). Five eco-efficiency ratios were estimated under three scenarios of the park: before the clustering system is formed, after the clustering system is formed, and a future optimum scenario (i.e. for situations the goal of "zero emissions" is being achieved). Results of this study demonstrate that overall eco-efficiency of the cluster following eco-industrialization could result in increases of up to 30-40% over the pre-eco-industrialized level

生态产业集群的生态效率评价

本研究采用生态效率指标框架，考察了工业园区的经济绩效和环境绩效。本研究以台湾中部常华沿海工业园区及其周边地区为研究对象。确定了一个由七家公司组成的生态产业集群，并锚定了一家大型钢厂，用于将产生的废物回收为建筑材料。(以下简称“生态工业化”)。利用一个经济指标(税后利润)和五个环境指标(能源消耗、水消耗、原材料消耗、二氧化碳排放和总废物产生)对单个公司的生态效率和整个系统的整体生态效率进行了量化。在集群系统形成前、集群系统形成后和未来最优情景(即实现“零排放”目标的情景)三种情景下，对园区的5个生态效率比进行了估算。研究结果表明，生态工业化后的集群整体生态效率比前生态工业化水平提高了30-40%
