Study On The Eco-industrial Park Development Of Suzhou High-Tech District

Industry is the pillar of national economy and industrial development is one of the main components influencing comprehensive competitiveness of a region. China, however, is confronted with some problems in industrial development: high pollution and low value in industrial transfers from developed countries and regions, trade friction and green barriers in international trade, conflict between environmental protection and economic development, shortage of resources. Under this background, eco-industry provides a new model to achieve the goal of industrial sustainable development. Eco-industrial Park (EIP), the carrier of eco-industry, is a new type industrial park designed under the ideas of Recycling Economy and Industry Ecology. Under the flows of materials and energy, factories and companies in EIPs are connected forming industrial symbiosis which is aimed to fulfill the goal of closed materials circle, cascade use of energy, waste minimization by resource sharing, by-product and waste exchanging and reuse. Nowadays EIPs are vigorously developed all over the world, which can also be seen in China under the proposal of SPAEC(State Protection and Administration of Environment of China).The thesis conducts an assessment on EIP of Suzhou High-tech District. Upon drawing the experiences from successful EIPs home and abroad, the thesis makes a summarization on the categories, characters and evolvement and identifies common factors leading to the success of EIPs. In the meanwhile, this paper builds an evaluation index system by absorbing present features of EIP of Suzhou High-Tech District and then puts forward suggests and recommendations in the hope of giving some enlightenment to solve the problems of Suzhou EIP.Thesis has six parts. The first part is the introduction regarding the background and meaning of choosing the topic, basic theories and research progress, research subjects and methods as well as the frame and brief line of the thesis.The second part summarizes the implementation of EIPs in the world. It is concluded that common factors for the success of EIPs include economic basis, construction of eco-symbiosis relation, pollution-free management, eco-planning and design, ecological technology. Characters of three types of EIPs are: anchor based, Venous Industry Based, Sector-integrate. It is indicated that most EIPs are in junior development stage.The third part expounds the industrial and economic background, evolvement and essential feature of Suzhou EIP.The fourth part conducts an assessment and analysis on Suzhou EIP. First this part designs the evaluation index system containing 5 primary indexes: economy level, eco-industrial symbiosis, park management, eco-benefits, environment quality, and 23 secondary indexes.The detailed good performance of the EIP can be summarized as rapid economic growth, the formation of the eco-industrial symbiosis, the improvement of management system including consultation, environmental assessment, training, fund support, etc, as well as a sound international eco-tech cooperation network. The inefficient issues are mainly: small investment in environmental protection, simple industrial symbiosis, incomplete eco-industrial system, low replacement of materials and by-product implying the rigidity of system, low level of technology sharing, lacking of message collection and management system of waste and by-product, insufficient cascade use energy system, low initiatives of the medium and small enterprises.The fifth part puts forward five optimization routes for the development of Suzhou EIP.The final part is the conclusion for the whole thesis and problems needed to be further discussed are also pointed out.Innovation of this paper lies in (1) spatial configuration of three agglomeration zones of EIPs in the world is identified: North America Zone, West Europe Zone and West Bank of Pacific Ocean and in the meanwhile the spatial features of China EIPs are also concluded; (2) types, characters and development stage of EIPs in the world are pointed out; (3) an evaluation index system is built for the EIP of Suzhou High-tech District...
