The Study On Operating Mechanism And Eco-efficiency Assessment Of Regional Industrial Ecosystem

Industrialization has dominated material production and economic development of human society since the Industrial Revolution in the 18th century. However, the traditional industrial production causes serious damage to the global ecology while meeting increasing material demands of people. Gradually people recognized that linear production of traditional industrial system had been difficult to maintain, a new production mode must be found to meet sustained and healthy development of human society, and industrial ecology offeres a new direction to change traditional linear production mode. Nowadays, ecological mode has been urgent need of industrial development for countries, and played an increasingly important role in regional economy. As a developing country, China is currently in the mid-term of industrialization, enterprises are still used to traditional linear production whih is characterized by extensive production with a large consumption of resources, this phenomenon leads to serious problem of industrial pollution and resources waste, and prevent the sustainable development of society and economy and the improvement of human living quality. Therefore, to turn extensive production mode of China's traditional industrial development into green and eco-model has been the urgent need of development of China's industry, and development of eco-industry has been the nevitable requirement and the only way for China to realize harmonious society. Under this situation, this dissertation takes regional industrial ecosystem as an object to study, with a view to provid theory and practice reference for strengthening the process of industrial ecology and improving the sustainable capacity of regional economy.This dissertation reviews former studies about industrial ecosystem, introduces the main theories of ecology, industrial ecology and recycling economics, analyzes the relation between regional industrial ecosystem and above theories, and by taking bove relation as the basic framework relation of the theory of regional industrial ecosystermon, this dissertation constructs a systematic and comprehensive theory of regional industrial ecosystem framework, and then build a theoretical foundation of the study. In order to analyze the operating mechanism and the efficiency of regional eco-industrial system comprehensively and systematicly, this dissertation constructs regional eco-industrial system, gives the defination of regional industrial ecosystem and indicates its characteristics. On this basis, this dissertation invstigates the overall structure, the industry chain structure and spatial structure of regional industrial ecosystem, and studies the function of regional industrial ecosystem from the aspects of production, aggregation, diffusion, and ecology.Based on the analysis of structure and function of regional industrial ecosystem, this dissertation investigates the operating mechanism of regional industrial ecosystem. From aspects of internal coupling and external coupling, this dissertation studies coupling mechanism of regional industrial ecosystem. From aspects of enterprises'internal demand, governmental action, resources depletion and technology feasibility, this dissertation analyzes dynamic factors of regional industrial ecosystem, and establishes of the dynamic mechanism model of regional industrial ecosystem. Then this dissertation indicates the non-linear essence of the evolution of regional industrial ecosystem, and establishes the logistic model of the evolution mechanism of regional industrial ecosystem. Furthermore, this dissertation researches symbiotic mechanism of regional industrial ecosystem from aspects of cost-push mechanism, efficiency-driving mechanism, environment-oriented mechanism and endogenous mechanism.In addition, this dissertation uses emergy analysis to study the assessment of eco-efficiency of regional industrial ecosystem. On the basis of introucution of Emergy evaluation theory, this dissertation constructs and analyzes emergy flow system of regional industrial ecosystem and designes assessment index system of egional industrial ecosystem.Finally, the dissertation takes Harbin industrial ecosystem as a study case, applies designed assessment index system to analyze and evaluate eco-efficiency of Harbin industrial ecosystem, and puts forward countermeasures and suggestions to promote eco-efficiency of regional industrial ecosystem from respects of enterprises,industry subsystem and support subsystems.
