| Human survival and its development is a huge system, while economy, resources and environment are the major subsystems, and economic development is subject to resource constraints all the time. China's economic development has long been on the traditional base of resource consumption, especially in the case of extensive business-oriented, resource-based, industry-intensive industries. The traditional linear model of economic development is characterized by high energy consumption, extensive resource consumption and serious environmental pollution, making pollution control and resource management difficult.Eco-industrial park (EIP) established on the basis of industrial ecology operates in the circular economy development model, so that the enterprises in the EIP improve usage efficiency of material and energy and the recycling of waste, reduce the production cost of the EIP, improve enterprise performance, and competitiveness. Through mutually change between waste and raw materials, the enterprises reduce the consumption of natural resources and environmental pollution significantly and improve ecological environment. The study on this mode of industrial parks development is to explore the development of EIP system mode of circular economy and the driving mechanism, establish an evaluation indices system and models of EIP establishment method, in order to provide a useful reference for the circular economy in EIP and for the shift of national economic growth model.The main content of this dissertation is as follows:1) On the basis of summary of circular economic theory, emergy theory and the theory and practice of EIP at home and abroad, this dissertation analyzes the level and framework for planning and building EIP, points out that the key is the integration of industrial ecological chain.The dissertation analyzes the important roles played by technical support, management and policy formulation improving the economic and environmental benefits of the park in the EIP operation, discusses the methods of creating technical support and management systems for the EIP, and the ways to use fiscal and tax tools to provide policy support for the implementation of circular economy development model.2) This dissertation summarizes three types of the enterprises'patterns of production based on recycle economy: products or waste recycling, and other system byproducts (waste) recycling and use of multiple products of this system, and the flow patterns of energy of each model. Then the paper proposes an emergy analysis method for various modes. It is the example of emergy analysis that the production patternls of concrete based on recycle economy. The results show that the emergy evaluation method could fully measure the three recycle economy models of production and the sustainability.3) In this dissertation, the principles of emergy analysis, a new analysis method on emergy consumption, are introduced. In order to extend the application range, the index is proposed, which is called Symbiotic Emergy Benefit Rate (SEBR). By thermal power plants and cement manufacturers symbiotic system consisting of case study to verify this research, the Symbiotic Emergy Benefit Rate (SEBR) can be used to analyze the effective rate of symbiotic system and explain the advantages of the emergy analysis.4) This dissertation introduces an EIP emergy evaluation index system to comprehensively reflect the EIPs eco-economic systems'structure, function and efficiency, and evaluate the relationship between environment and the economy, man and nature of the EIPs.5) Emergetie ternary diagram analysis was used herein to analyze two industrial agglomeration systems in Liaoning Province of Northeast China and compare resource use, eco-efficiency and sustainability, and predict and select development path for the future. The results of the analysis demonstrated ternary diagrams are used as a tool to compare and evaluate the improvement of the two industrial agglomeration systems, and then the development path is predicted and selected. The emergetie ternary diagram is a versatile and adaptable tool for emergy analysis.The innovations of this dissertation:1) Use of emergy analysis method to evaluate the three Enterprise Product recycling economic models.2) Design of the Emergy Efficiency Index of Industrial Symbiosis - Symbiosis Emergy efficiency ratio (SEBR).3) The value of the phase diagram are used in the evaluation of eco-industrial efficiency to expand the application scope of phase diagram method and provide a visual expression of tool for the evaluation of eco-industrial efficiency.
