Evaluation of symbiotic of waste resources ecosystem: a case study of Hunan Miluo Recycling Economy Industrial Park in China

China had approved to construct 49 urban mineral industry demonstration bases from 2010 to 2015, which indicated that the Chinese Resource Recycling Industry (RRI) has been transferred into the social circulation patterns process after experiencing a micro-pattern and park-pattern. With the rapid progress of industrial process, the RRI presents some features just like system relationship is increasingly tight coupling, technology integration and innovation are accelerating, affecting factors are more complex, policy response is more sensitive, etc. All these changes have made the research of industry ecosystem symbiosis more complicated. In this paper, we divide the renewable resource recycling system into “management, marketization, supply, recovery, resource” five sub-systems firstly, then analyze the industry ecosystem symbiotic relationship by integrating the use of complex system theory and catastrophe progression model. Secondly, we establish the comprehensive evaluation index system including symbiosis mode, symbiosis environment and symbiosis level. We conduct Catastrophe Progression Method (CPM) into the comprehensive evaluation of the industrial symbiosis ecosystem. By using the control variables and state variables of CPM, the key factors and indexes changes are described. Finally, the model and method are utilized for evaluating Hunan Miluo Recycling Economy Industrial Park development between 2013 and 2018. The results are found to be coincident with a practical situation, which proves that the catastrophe progression method works well. The method is proved to be feasible in practice and has high objectivity and reference value.
