| With the rapid development of industrialization, many kinds of industrial parks emerge continually. Industrial parks, however, exacerbate the global eco-environment and deplete speedily the un-renewal resources when they provide rich products and improve the economic rapid development to the human society. Hence, the eco-development of industrial parks not only resolves the key problem of the conflict between human beings and the nature, but also realizes the radical problem of social sustainable development. Currently, the patterns of course economic increase haven't been transformed completely in China, which brings the results that the impact of resources restriction on economic development stands out. Implementing circular economy and improving the efficiency of utilizing resources in industries have become an inevitable strategy task to realize sustainable development during the period of "The eleven-five". The main development direction for Chinese industries is to realize the evolvement from industrial parks to eco-industrial parks. To standardize the ecological construction of industrial parks and to evaluate the processes of the constructions and reconstructions, we need to use scientific evaluation methods to evaluate synthetically after analyzing the traits of industrial parks.Based on the background of eco-development of industrial parks and the core of Eco-efficiency, the main contents of Eco-efficiency of industrial parks are discussed, a method and a model to quantitatively scale Eco-efficiency of industrial parks are put forward, and an evaluation indicator system and a method based on the Eco-efficiency scaling are also establish in this dissertation.Firstly, most of the theories Eco-efficiency related in land and abroad deal only with corporations, and most of researches keep inside corporations or the lays of processes and manufacture flow. They focus on the understanding and analysis on Eco-efficiency concept. Aiming at the existing problems of the singleness in research visual angle and of unclear conception, the author systematically sums up and analyzes the relative literatures, and points out the localizations of the existing system info and research methods in this dissertation. As the start of the theoretical research, the contents of Eco-efficiency of industrial parks are defined, and expanded to middle-lay (industrial parks), that educes the concept of industrial park's Eco-efficiency. Based on the analysis on the relationship between Eco-efficiency and material reduction, economic increase, environmental burthen and Environmental Kuznets Curve, the bridge function of Eco-efficiency in realizing the goals of economic increase and material reduction in industrial parks is researched, and the economical and environmental two-dimension characteristic of a eco-system is described by Eco-efficiency. Eco-efficiency is not only the rational scale of industrial parks, but also the standards of scaling eco-development of industrial parks. As the token of continual development, improving Eco-efficiency is a strategy to transform industrial parks, further more, a method to scale the process of the strategy, and also a goal of ecological construction of industrial parks. The combination of Eco-efficiency theory with the ecological construction of industrial parks expands the research boundary of Eco-efficiency from the point of theoretical system, and also offers a theoretical basis for scaling indicators and ecological evaluation method.Secondly, in order to resolve the difficulty of scientifically quantifying Eco-efficiency, this dissertation, based on the systemic theory and the economical and environmental two-dimension characteristic of Eco-efficiency, constructs a method named Emergy-Material Flow Analysis by means of combining the methods of emergy analysis and material flow analysis. The traditional GDP/GNP is taken placed by Enmy (unit Em$) to measure the gross value of the whole out-put of the system, and DMI is taken as the measuring indicator of the consumption of material resource. By amending the traditional model of EE, the quantitative evaluation method and model of EIPs is set up based on Emergy-Material Flow Analysis.The combination ideal put forward by this research includes indicator combination and method combination. The core is to scale Eco-efficiency of industrial parks from the point of two-dimension view of the combination of energy value-currency value with weight view, and to construct relationship model. After confirming characteristic indicators and derivative indicators describing compound ecological and economic system of industrial parks, this dissertation deepens and improves the contents of Eco-efficiency of industrial parks by means of researching the phenomenon of De-link and Re-link during the process of eco-development of industrial parks.Eco-efficiency indicators are relative ones, which means that other indicators must be involved in scaling the relationship between utilizing nature resources and developing economy. To synthetically evaluate the eco-development level of industrial parks, an evaluation indicator system and an evaluation method system were constructed in this dissertation based on Eco-efficiency. After analyzing and constructing the industrial park eco-development function, this research establishes a PSR indicator system framework about industrial parks by borrowing "pressure-state-response" model. With this framework as the system level, the variables in the development function as the target level, the indicators were selected and their contributions were also confirmed by the method of Delphi in the dissertation. This indicator system integrates some quantitative indicators as emergy analysis and material flow analysis, Eco-efficiency measurement, eco-management performance, stands out the wholeness and oneness, describes the system capacity and each resource's Eco-efficiency. The method of Grey cluster's analysis model is used to synthetically appraise the eco-development of industrial parks, the result of which can be used to synthetically analyze eco-development of industrial parks according to "the rain glass of sustainable development".Finally, this dissertation collects Dalian Economic and Technological Development Zone (DDZ) as the empirical study to scale its Eco-efficiency and synthetically evaluate its ecological level. With the energy analysis and material flow analysis in DDZ as the research contents, the results of analyzing all indicators show that the environmental burthen in DDZ is relative high, Eco-efficiency relative low, the ability of sustainable development relative weak, and the ecological level elementary. Hence, DDZ needs to deepen the ecological project constructions, to build eco-industrial chains and industrial symbiosis network, to control the gross, and to optimize the resource configuration from the point of long term benefit and macroscopical view, which is helpful to improve its Eco-efficiency, and finally to realize sustainable development in DDZ. This research also puts forward suggestions on how to improve DDZ's Eco-efficiency after analyzing the factors and environments driving DDZ ecological development.Investigations were taken in this dissertation on quantitatively evaluating eco-industrial development by using the theory of Eco-efficiency, and the Eco-efficiency and its evaluation method of industrial parks were also analyzed, which provides a theoretical basis and an evaluation method for the eco-design and decision analysis of industrial parks, and also offers an analysis tool and a theoretical support for the eco-development transformation of existing industrial parks.
