Retrospective Study On Economic Performance Of Eco-industrial Parks In China

Eco-Industrial Park (EIP) is one of circular economy development models combined industry and ecology. There are lots of research on environmental effects of eco-industrial parks,while the analysis of economic performance still needs to be farther evaluated. Based on the review and economic evaluation of both domestic and regional eco-industrial parks, In this paper, An economic evaluation system of eco-industrial parks is proposed and the economic performance of Chinese eco-industrial parks were evaluated according to it. The main contents are as follows,1、The research on the status of development of the domestic eco-industrial parks were conducted in different regions, different types of industries,different construction stages and at different levels of economic development.The development problems of eco-industrial parks were researched in a comprehensive way in order to provide references to the construction of national eco-industrial parks during "Twelve Five" period.2、In order to establish the performance evaluation model for eco-industrial parks, An evaluation index system of economic performance in eco-industrial parks was established and the distance function method was chosen to give a comprehensive evaluation.3、In order to evaluate the industrial symbiosis efficiency of eco-industrial parks and to conduct the research on the associated mechanism with the economic performance of eco-industrial parks, An evaluation system on industrial symbiosis efficiency of eco-industrial parks was established. The establishment of the associated mechanism system between industrial symbiosis efficiency and economic performance of eco-industrial parks provides a theoretical basis on the internal mechanism of economic performance in the eco-industrial parks.4、Evaluation and analysis of the economic performance of selected domestic eco-industrial park s was conducted. Meanwhile, correlation analysis and research is conducted to illustrate industrial symbiosis efficiency and economic performance of eco-industrial parks, ultimately revealing the inherent mechanism of eco-industrial park economic performance and proposing suggestions for future economic sustainable development of eco-industrial park in China.
