Research On Coupling Among Enterprises In The Construction Of Eco-industrial Park

As a new form of industrial organization imitating natural ecology material circulating, ecological industry has been paid more and more attention on its application and practice by governments and academia at home and abroad. Eco-industrial park is the key practice of ecological industry, which construction has acquired remarkable achievements.Based on the research of the relative literatures and examples, laying particular stress on the enterprises' coupling, taking Longmen Eco-industrial Park as an example and through theory studying and demonstration analysis, some main conclusions was obtained as follows.Firstly, based on summarizing of Eco-industrial park's development course and applications of coupling idea, it was pointed out that the coupling existed in three administrative levels: inside enterprise, among enterprises, and between park and region. Then, the coupling among enterprises was pointed out as the most important part among the construction of Eco-industrial Park through the analysis of the three level coupling.Secondly, through studying the coupling among enterprises, its principle, content and steps were put forward, and then material metabolism, optimising analysis and coupling evaluation was pointed out to be the important tools for coupling among enterprises.Thirdly, taken the Longmen industrial park in Hancheng city of Shaanxi province as an example, some coupling models of the entire park and main trades have been concluded after broadening and linking the industries.Fourthly, taken the main matter in park as object and applied metabolism-analyzing methods, the coupling effect was calculated and the result indicated that the efficiency of resource utilization and wastes recycling ratio were improved notably.Finally, the effect and benefit analysis showed that economic, ecological and social benefit of the enterprises coupling were very remarkable.Cheng Jinxiang(Environment Science)Directed by Ma Junjie...
