Studies On The Desigh Of The Eco-Industry Chains And On The Assessment Index System Of Its Stability-Giving The Examples Of EIPs In Yantai And Urumchi

The ecologic industry refers to an industrial pattern in which the industrial production system is planned by imitating the circulatory mode of substances in the ecologic course of the nature. The Eco-Industry Parks (EIPs) are an important form of practicing the eco-industry. In the development countries such as the USA and Western Europe, the EIPs are developing increasingly more rapidly. In China, the construction of EIPs is at the flourishing phase of development.In the EIPs, the eco-industry chains are formed by imitating the operating pattern of the natural ecologic system, in which the wastes of one manufacturing enterprise become the raw materials of another. The structure of the eco-industry chains determines the key factor of stability and sustainability in the whole industrial eco-system of the EIPs.The building of eco-industry, planning of EIPs and the vecent research on the stability of the industrial eco-system have been summarized in the paper, the developing modes if the EIPs both at home and abroad have been compared and analyzed. The paper also advocates the necessity of developing the EIPs in China.On the basis of the theoretic analyses and summarizations and also based on the principles of the eco-industry and Yantai EIPs which represents the eastern coastal economic development of China and Urumqi EIPs which represents the western economic development of China, the paper provides the studies on the industrial chain planning in the course of desigh with the emphasis on the studies of the spreading and expansion of industrial chain of the eco-industry; the mechanism of choosing the key industries; the intergrouth of the eco-industry parks.
