Abstract: Construction of eco-industrial chain can promote eco-environmental protection,and realize harmonious development among resources,environment and economy.Role selection is a vital supplement to the eco-industrial chain.An index system is set up on the basis of environmental pollution.This paper uses the principal component method to analyze the role selection of eco-industrial chain of Chongqing’s Changshou economic development zone.It shows that metallurgical and chemical industries are producers;general and specific manufacturing and transportation are consumers;paper&print and non-metallic production are decomposers,which are less in Changshou economic development zone with a less exchange in by-products.This paper suggests developing a suppositional eco-industrial chain,boosting environmental protection construction,and researching the renewable technology on wastewater and gas.

Key words: eco-industrial chain, role selection, principal component analysis, industrial zone, Changshoue conomic development zone

摘要： 构建生态产业链有助于生态环境保护,实现区域内资源环境经济协调发展,角色选择的实证分析是对生态产业链内容的重要补充。构建以环境污染指标为主的指标体系,运用主成分分析法对重庆市长寿经济技术开发区进行生态产业链的角色选择分析。研究表明,钢铁冶金、化工行业是生产者,通用、专用设备制造业和交通运输设备制造业是消费者,造纸印刷业、非金属矿物制品业是分解者。长寿经济技术开发区内分解者较少,副产品交换少,建议发展虚拟生态产业链,加强环保产业建设,研发废气、废水利用技术。
