| The economic circle around Bohai Sea has a particular area advantage; it is the economic center of Northeastern Asia and plays an important rule in the juncture between Asia and Europe. It is outstanding on the advantage of resources, the basic of marine industry is abundant and the industry presents the state of specialization and centralization. The total production of marine industry and increasing value of this area hold the balance in China, the economic circle around Bohai Sea is named the third pole which leads the economic development of China. However, in the development of marine industry around Bohai Sea, lacking in effective system leads to low-level repeated building, inferior industrial structure and weak effect of territorial centralization. The result effects the best deploy about the environmental resources in this area, it makes us face the flinty environmental problem.The paper cites the coupling relationship from physics; it is the first time to use coupling in the research of environmental resources. We synthetically apply environmental economics, econometrics, industrial economics, systematic science and other relative ways to the research, explore the coupling theory and coupled coordination between the marine industrial cluster and environmental resources in the economic circle around Bohai Sea, and then design the coupling mechanism which promotes the harmonious between the marine industrial cluster and environmental resources, so as to improve the cooperation of the area.The paper firstly uses SWOT model to analyze strengths and weaknesses, opportunities and threats of marine industry in the economic circle around Bohai Sea, builds decision-making matrix and finds out the competitive advantages of the marine industrial cluster. Then it measures the industrial cluster through the improved LQ way; analyze the location quotient of Chang San Jiao, Zhu San Jiao and the economic circle around Bohai Sea, and thinks that the industrial cluster of the economic circle around Bohai Sea falls behind, especially the difference between the second industry and the third industry. On the basic of environmental factors, such as gifted nature, pollution, labor resources, technological innovation, social capital and etc, we analyze the effect of environmental resources to the development of the marine industry by using the grey related model and regressive analysis. So we can get the result that capital takes the dominant place in the effective factors of the marine industrial cluster around Bohai Sea, and then the external factor is the degree of market. At the same time, we can't ignore the effect of environmental resources to the marine industrial cluster, when the pollution increases 1 percent, the total production of marine industry around the Bohai Sea will reduce 1.208 percent; we also study the economic effect of the marine industrial cluster to the environmental resources in this area. It includes resource-centralization effect, economic avoiding effect, FDI effect, technological spillover and technological innovation effect. We make the detail analysis using grey related model, regressive analysis and layer analysis method on the basic of criterion analysis, we get a result that cluster of the marine industry highly influence the employment of this area, and the marine industry around Bohai Sea has not become the leading industry in attracting foreign direct investment. With more and more scholars and institutions studying in this area, technology will become the Granger reason of economic increase, technological spillover and technological innovation effect will be clear.On the basic of systematic theory, we creatively design the coupling parameter of industrial cluster and environmental resources, build coupled coordination model, and then estimate the coupled coordination degree of industrial cluster to environmental resources around the economic circle of Bohai Sea, predict the coupling relations of the above two factors by neural networks .Using the Granger-causality test open out the coupling mechanism of dynamic association between the factor of environmental resources and industrial cluster. The result tells that the coupled coordination degree between the marine industrial cluster and environmental resources around the economic circle of Bohai Sea is becoming better and better. We design the coupling system of sustainable development to the marine industrial cluster and environmental resources around Bohai Sea, and try to harmonize the environmental resources and marine industry. |
