Abstract:The development of industrial symbiosis network(ISN) is the core task of establishing an eco-industrial park. Driving factors and obstacle factors of influencing the ISN emergence were summarized from the enterprise’s perspective based on historical documents; key factors were tried to discover through questionnaires and factor analysis. The results show that influence factors can be summarized as six areas of economy, technology and resources, corporate knowledge and ability, policies and regulations, cooperative atmosphere, environmental awareness and effectiveness. Among them, economic, technology and resources factors are the key factors influencing the ISN emergence. It is more effective to facilitate enterprises to implement the projects of industrial symbiosis by rigorous controlling policies compared to incentive-based supportive policies. Corporate knowledge and ability are important impediments of the ISN emergence. Finally, the paper puts forward some policy suggestions based on the results in order to develop ISN.
