| Industrial symbiosis can not only form industry convergence effect but also improve ecological efficiency. It is the basic characteristics of Eco-industrial Park and an emphasis of the research. Eco-industrial Park is an intensive development model, which breaks the former small and scattered company pattern, favors the circular utilization of natural resources, reduces the cost of pollutants, contributes to lessen the conflict between the economy and environment, and is favorable to transformation of pattern of economic development. However, from the research at present, we can see the research of relations between companies in Eco-industrial Park is not systematic, and we don't have deep research on the mechanism of symbiosis between companies. Thus, I would use ecological theory and transaction cost theory as support, I would collect information from the relations between companies in Eco-industrial Park through questionnaire and deep face-to-face interview. After the investigation of companies in Eco-industrial Park, I would compare the different symbiosis model, analyze the mechanism of symbiosis to unfold the general developmental law of symbiosis between enterprises in Eco-industrial Park.This article consists of six parts in all. The first part briefly explains the topic-selecting, the background, target, the progress of motivation theories and significance of the research. Then, it explains the development condition and problem of Eco-industrial parks (EIP), the third part pays more attention to form, character and model of enterprise symbiosis of enterprise symbiosis. And the fourth part analyzes enterprise symbiosis mechanism of Eco-industrial parks, then, the fifth part is a demonstration, based on the case of XinGou Eco-industrial parks in Wuhan, the structure of industrial ecological chains, the model of industrial symbiosis, the benefits of industrial symbiosis and the mechanism of industrial symbiosis in this eco-industrial system was analyzed in this paper. The last part obtains the conclusions, and gives ont the farther problems of research. The study showed the eco-industrial system of XinGou Eco-industrial parks is a model of self-controlled symbiosis, it is an industrial symbiosis model of core surrounded in the system and the alcohol factory is the center. There are six symbiosis relationships in the symbiosis network. One of those is symbiosis of partial benefit, the others are mutual, all the relationships have positive effects on the environment an,el produce good symbiosis benefits. The motivation of enterprise participation in industrial, symbiosis is saving cost, improve ecological benefit and form industry convergence effect.This paper gives a systematic research on symbiosis mechanism in Eco-industrial Park mainly according to symbiosis theories in ecology and market cost theories in economics. It gives further practical analysis combined with theoretical research, innovating in methods and content of reseach. |
