| Entering the21st Century, low-carbon, environment protection and ecology become new topics of the era, with the prominent contradiction among global population, resources, environment, industrialization acceleration and rapid economy growth. At present, water resource and air pollution become much worse in China. The extensive development with immoderately consumption of energy and resource is unsustainable, which makes the ecological friendly and resource saving development mode a necessary. The industrial parks shall face the impact during this transition process, which makes the functional reorganization and ecological upgrading unavoidable. As the hinterland of the Yangtze River Delta, Zhenjiang shall plan and act in industry ecological upgrading to grasp opportunities in future competition, under the multiple pressures of national development strategy adjustment, integrated industrial upgrading in the Yangtze River Delta, its own economic structure reorganization and so on.This dissertation starts with the discussion of ecological upgrading on traditional industrial park through three-dimensional coordinate research structure with ecological niche, industry association and ecologicalization. The discussion is based on current research situation and theory on industrial ecology at home and abroad. In order to objectively, comprehensively and scientifically evaluate the industrial ecosystem, the following principles should be kept in establishment of evaluation index system:dynamic and static unity, completeness and significance combination, system and hierarchy combination, scientificity and comparability combination, guide and maneuverability combination, qualitative and quantitative combination. This dissertation is mainly present an evaluation index system framework from the angle of theoretical analysis, determine index’s weight coefficient by using Analytic Hierarchy Process (AHP) method, and makes integrated evaluation by further weighted summation. It specifically relates to3class-Ⅰ indexes, as comprehensive park development level, park sustainable development ability, park coordination degree,10class-Ⅱ indexes, as economic performance level, environmental quality level, social development level, economic sustainable development ability, environmental sustainable development ability, social sustainable development ability, economy and environment coordination degree, environment and society coordination degree, society and economy coordination degree, policy and management level, and66class-Ⅲ indexes.Guided by above-mentioned analysis, this dissertation emphasizes in empirical analysis the internal and external condition for industrial ecological transformation and upgrading of Zhenjiang Economic and Technological Development Zone. Also, this dissertation deeply discusses the path and method for its industrial ecological transformation and upgrading. Based on its current existing industrial structure, this dissertation compares in details and analyze deeply on its pillar industry structure. By using the optimized Resource Exchange Model of Producer, Consumer and Decomposer, it estimates and analyzes in details on the generalized ecological structure of Zhenjiang Economic and Technological Development Zone. All these works explore the foundation, influence factors and future development direction on industrial structure ecological upgrading of Zhenjiang Economic and Technological Development Zone.Through the detailed analysis, this dissertation finds out that the industrial ecological system of Zhenjiang Economic and Technological Development Zone is in the initial stage of Class II industrial ecological system with some sight of Class-Ⅲ. Considering its characteristics of relevance and intergrowth, Zhenjiang Economic and Technological Development Zone should upgrade its existing industrial structure based on the already-formed Class-Ⅱ industrial ecological system. Of course, Zhenjiang Economic and Technological Development Zone should cultivate or construct the enterprises or industries reperesenting Class-Ⅲ industrial ecological system in advance at the same time, to guide the timely transformation and upgrading of the whole Class-II industrial ecological system. Then finally establish sustainable, low-carbon, Class-Ⅲ industrial ecological system. At the end of this dissertation, it offers a series of specific suggestions and proposals on upgrading path for Zhenjiang Economic and Technological Development Zone. Due to the particularity of Zhenjiang Economic and Technological Development Zone and difficulties to obtain some data, this article abandons some indexes when analyze its industrial ecological development. In the new index system, different index has different weight. Through specific analysis, result shows that the comprehensive park development level, park sustainable development ability, park coordination degree of Zhenjiang Economic and Technological Development Zone is gradually increasing from2007to2011. And its industrial ecological development index is also gradually increasing year by year according to collective weighted average. Base on exiting industrial base and park construction, Zhenjiang Economic and Technological Development Zone shall grasp development opportunities at home and abroad, speed up industrial ecological upgrade or transformation and speed up construction of modern service industry to realize the transformation of economic development growth pattern and low-carbon, environment-friendly and sustainable development. Only with the combination of internal development and external condition, Zhenjiang Economic and Technological Development Zone will successfully achieve industry ecologically upgrade. |
