Analysis Of Eco-industrial Chain Network And Evaluation Of Its Stability In Eco-industrial Parks

As a big developing country, we must improve social productivity, general national power and standard of living while being confronted with big population, lesser natural resource, the industry pollutions and low economic development level. Eco-industrial Park is important part of the circular economy and is also the best way to operate industrialized procession, which can also reduce pollution and improve the efficiency of resource use as well as protect environment. Construction of eco-industrial chain network is the primary part of Eco-industrial Park. So the research on eco-industrial chain network in Eco-industrial Park has important academic and applied value.The paper firstly reviews and analyses the related theory basis and concept of Eco-industrial Park and eco-industrial chain. In the view of form, link and linked ecological level of eco-industrial chain, the paper gives its analysis. In addition, the paper constructs comprehensive evaluation system of stability of eco-industrial chain network. Moreover, the paper carries out field survey by supporting of an important reseach project preside by supervisor and conducts the comparison between two eco-industrial chain networks.Primary content and innovation include:1. The analysis of form, link and linked ecological level of eco-industrial chain. The paper analyses the formation conditions of eco-industrial chain. On the basis of it game theory, link and different relation between conterminous enterprises in eco-industrial chain is given. Moreover, the paper compares linked ecological level between different eco-industrial chains by Gray Relation Decision-making mode.2. The analysis of construction of eco-industrial chain network. Four eco-industrial chain networks are put forward. In the meanwhile, relation of primary and minor enterprises in eco-industrial chain network is analysed. Approach of construction of eco-industrial chain network to Eco-industrial Park in our country is given.3. The comparison of eco-industrial chain network between Wulan cement group and Mengxi industrial park. On the basis of analysis in detail by using of case study, the paper draws common ground and differentia.4. Comprehensive evaluation system of stability of eco-industrial chain network. Fuzzy evaluation is used in its analysis. In the meanwhile, a example about mengxi industrial park is given. Besides, the paper makes some suggestions on how to improve the stability of Mengxi industrial park.
