A Research On Optimization Methods Of Sustainable Development Of Ocean Economy In Shandong Peninsula

With abundant marine resources, outstanding location advantages, and prominent strategic position, Shandong is a large coastal province of economy. On April 2009, General Secretary Hu Jintao proposed to build Blue Shandong Peninsula Economic Zone during his inspection tour in Shandong, which was a strategic vision from the national point of view. With the gradual formation of the Blue Shandong Peninsula Economic Zone and the promulgation of the Development Plan of the Yellow River Delta Efficient Ecological Economic Zone, a major strategic opportunity is offered to the development of the Shandong Peninsula marine economy. However, at the same time, it should come to people's notice that there are still many problems such as the increasingly depleted marine resources and the seriously polluted marine environment lying in the development of the Shandong Peninsula marine economy, which is more than just a question of development but the question of whether it can maintain and how to maintain a sustainable development as well.Based on the concrete situations of the development of the Shandong Peninsula marine economy, this thesis firstly adopts approaches like sustainable development theory and analytic hierarchy process to quantitatively analyze and evaluate the sustainable development degree of the Shandong Peninsula marine economy. And then comprehensively adopting methods of evolution theory of the industrial structure, industrial cluster theory, theory of blue economic zone and model analysis, the thesis analyzes the optimum methods of the sustainable development of the Shandong Peninsula marine economy in terms of the choice of the leading industries, the optimization of the industrial layout, and the optimization of the regional layout, with the purpose of providing a feasible development path and theoretical guide for the sustainable development of the Shandong Peninsula marine economy.Taking the achievements of the research on the sustainable development both at home and abroad for reference and based on the concrete situations of Shandong Peninsula, the thesis at first establishes a sustainable development index evaluation system of Shandong Peninsula's own character, then defines the index evaluation standard value according to marine economic development domestically and internationally and various marine industries development standards, and adopting analytic hierarchy process to evaluate the index, finally the thesis comprehensively analyzes and evaluates the degree of sustainable economic development. The conclusion is:the degree of sustainable economic development of Shandong Peninsula is 0.55, which means a medium degree at the moment. To be specific, the main factors that constrain Shandong Peninsula marine economy from the sustainable development are as follows:regional marine GDP per capita; the proportion of marine technology funds to regional technology funds; the proportion of marine high-tech industries to marine GDP; the proportion of marine science and technology personnel to marine related employees; labor productivity of Shandong Peninsula marine economy; the proportion of the total area of the marine nature reserves to the total area of the coastal region; the ratio of marine GDP to the comprehensive utilization of the regional industrial solid wastes; and the ratio of marine GDP to the quantity of the regional industrial wastewater directly discharged into the sea. It will take 14 more years till the year of 2021 for Shandong Peninsula marine economy to enjoy a relative high degree of sustainable economic development, which means 0.8-0.85Based on the analysis of sustainable development of Shandong Peninsula marine economy, the thesis studies the optimum methods of sustainable development of Shandong Peninsula marine economy in terms of the optimization of industrial structure, the optimization of the industrial layout, and the optimization of the regional layout. As for the optimization of the industrial structure, under the guidance of evolution theory of industrial structure and theory of leading industries, the thesis conducts a comprehensive analysis and evaluation of the major marine industries of Shandong Peninsula by the means of developmental tendency analysis, total contribution analysis, growth contribution analysis, and forecasting future development, and analyses the marine strategic industries that will be well cultivated in the future by adopting Boston Matrix. It is concluded that the leading industries of Shandong Peninsula are coastal tourism, marine transportation, marine fishery, shipbuilding and ship repair, marine oil and gas industry. What will be well cultivated in the future is the marine high-tech industries. As for the optimization of the industrial layout, by comprehensively adopting industrial cluster theory, grew correlation degree analysis, coordinative development, the thesis maps out the developmental direction and key point of the future Shandong Peninsula marine economy. As for the optimization of the regional layout, under the guidance of theory of blue economic zone and the principles of dislocation development and mutual complementing with each other's advantages, the thesis analyzes the developmental direction and layout key point of marine economy of 7 coastal cities of Shandong Peninsula,which are Qingdao, Yantai, Weihai, Binzhou, Rizhao, Dongying, Weifang, and it puts forward the layout of the Shandong Peninsula Ecological Reserve as well.
