Research On Ecological Transformation Of Industrial Park And Its Eco-efficiency

Abstract:The practice of eco-industry made a great progress in our country, but a late start. There are dozens of industrial parks approved by the State named eco-industrial park, however, compared with some foreign-developed eco-industrial park, the parks can only be considered in the prototype or the formation stage. The more traditional industrial park is undergoing ecological transformation and upgrading practices. In the two-oriented society construction background, how to orderly obtain industry park ecological transformation goals and meet the standards of eco-industrial park, meanwhile, how to meet the new requirements of two types society construction, this is a complicated systematic project. However, there are many problems in practice. The power of ecological transformation and upgrading is not enough. The product and waste exchange chain has not fostered in the ecological prototype stage of industrial park. The relations coordination of participating body or elements in park is very difficult, and so on.However, the current theory does not give a satisfactory solution to the above problems. In view of this, according to the following analysis path"theoretical analysis-transformation power exploration--analysis of the transformation internal mechanism--eco-efficiency evaluation--eco-efficiency factors analysis-policies and strategies design", The paper carried out an systematic analysis on ecological transformation of industrial park and its eco-efficiency and abtained the following related conclusions:(1) Based on "resource conservation&environment-friendly" concept and eco-efficiency idea, a power model of industry park ecological transformation and development was established, and all of the power factors were classified and stratified according to importance degree with fuzzy clustering analysis method. Firstly, after investigating the first venture motives of industry park, we draw a conclusion that the first venture power and main purpose is to pursue economic interests. Secondly, surpassing the extensive development mode and ideas of the first venture, we draw a conclusion that the eco-efficiency should be strategic orientation of industry park ecological transformation, and the eco-efficiency is a a measurement tool and also is a management philosophy. Furtherly,from "enterprise,technology, market and government" several perspectives, the power model of industry park ecological transformation was established. Particularly, the results showed that the resource inventory,environmental carrying capacity constraints is critical and prominent.Finally, all of the power factors were classified and stratified according to importance degree with fuzzy clustering analysis method and the relationship among these factors was explored.(2) The internal mechanism of industry park ecological transformation and upgrading was explored. Firstly, we analyzed the process mechanisms of industry park transformation, the characteristics of industry park system achieving transformation was analyzed with the dissipative structure theory(a branch of complexity science theory). What's more, the mathematical conditions of dissipative structure formation was researched with entropy flow analysis method, or the dissipative structure identification standard of industry park system was established. Secondly, the transformation implementation mechanism of the park system was studied with the logistic equation that describes the biological population growth law. Synergistic surplus and symbiotic effect of "1+1>2" was achieved through enterprise symbiosis, and the symbiotic effect led to the goal achievement of system evolution. Thirdly, transformation security mechanism of park system was explored from the viewpoints of communication, trust and social capital. This chapter will contribute to in-depth understanding about the park system inside transformation mechanism.(3)The eco-efficiency of specific industry park that select eco-operation mode was measured. Firstly, we compared and summarized the current eco-efficiency evaluation methods, and select the gray correlation analysis method and super efficiency DEA method as the basic evaluation methods of park eco-efficiency overall level. Secondly, we established a conceptual framework" resource-saving--environment friendly--sustained economic--innovation oriented--human development" to build a eco-efficiency measurement indicators suitable to integrated eco-industrial parks (especially, the comprehensive eco-industrial park dedicated to high-tech industries development).Thirdly, eco-efficiency of Teda Industrial Park and Xiangtan Jiuhua Industrial Park was measured respectively based on gray correlation analysis and super efficiency DEA method. Evaluation results have important reference value for recognizing their own status, identifying gaps, determining the goals and direction of relevant parks, and also has important reference value for the sustainable development of the same type parks.The results will provide strong empirical support for making management descions to enhance eco-efficiency.(4) The factors that affect the park eco-efficiency were empirically analyzed and the effect of the relevant intermediary variables was verified.Firstly, we selected the structure equation model as a research method. Secondly, after reading a lot of literature and summarizing, a conceptual model was established that describe the park eco-efficiency influencing factors. What's more, we made a number of hypotheses. Thirdly, corresponding data of measurement scales was obtained through the questionnaire. We carried out the model fitting, adjustments and amendments based on tructural equation model with AMOS software. Uultimately, we got the corresponding optimal model that describe the relationship among latent variables and its indicators. The results shows that the factors "enterprises, industrial symbiosis, park management, market and cultural factors" make direct impact on the park ecological efficiency, and there is indirect impact on ecological efficiency through mediating variables.The results can provide important support for making measures to improve the park eco-efficiency.(5) The means to achieve industrial park ecological transformation goals, ecological transformation were deeply analyzed. These policy recommendations were analyzed specifically from several aspects "the enterprise, industrial symbiosis, park management, government and external environment". At the corporate level, we should be promote cleaner production technology application, and actively cultivate ecological awareness of employees and managers. At the industrial system level, we should further consolidate and develop the eco-industrial chain. At the park (including local government) level, we should promote optimal management system, such as building information sharing platform, establishing materials exchange system, constructing the environmental management systems. Further, based on the actual situation in Hunan Xiangtan Jiuhua Industrial Park, we proposed a series of measures aimed at improving ecological transformation and enhancing eco-efficiency of the park.
