| The 21st century is the century of ocean, which is the slogan proposed by the United Nations as early as in 2001. All countries recognize the importance of the ocean in the national economy and have drawn up marine development strategy for large-scale, comprehensive development and utilization of marine areas. Marine economy has become the most promising areas of the national economy, and has become the world’s new economic growth point. Developing the marine industry is one of the most realistic and effective way to solve the pressures of the population, resources and environment. As a maritime province of China, the marine industry of Shandong has developed rapidly in recent years, and the total marine economy continues to grow. Marine industry has become an important pillar industry of national economic development in Shandong Province, Shandong Province, but in the back of sustained and rapid growth of the marine industry, there are some issues, such as the low efficiency of resource use, severe ecological damage, irrational industrial structure and lack of technological innovation capability, resulting in the weakness of the overall competitiveness of the marine industry, while the marine industry cluster is one of the effective ways to improve the overall competitiveness of the marine industry.Based on these aspects, the paper study the marine industry cluster development of Shandong Peninsula Blue Economic Zone in order to promote the development of the marine industry cluster and enhance competitiveness of the marine industry as an effective way and a theory supporting. First, on the basis of introducing related theory including Shandong Peninsula Blue Economic Zone, industrial clusters, marine industrial clusters, the paper summarize the state of the marine industry cluster development, and further pointed out the problems mainly including serious low quality and isomorphic industries, marine resources and environmental problems, lack of technological innovation, backward management and coordination mechanisms. Second, the paper analyses the Shandong Peninsula Blue Economic Zone marine industry cluster. Qualitative analysis of marine industry cluster development factors by means of Michael Porter diamond Mode has concluded that marine industry possesses the basic conditions for the formation and development in the four key elements of production factors, demand conditions, related industries and business strategy, structure and competition. If grasping the opportunity and the Government’s policy support, the Shandong Peninsula marine industry cluster is bound to have good prospects for development. Using location quotient methods measure the marine industry cluster. From the overall level of the marine industry cluster, Shandong marine industry in China has formed a relatively cluster development and strong potentiality. From the point of view of the ocean three industries, the first industry has marine industry cluster phenomenon, but the degree of clustering does not have an increasing tendency. The second marine industry in the country has a comparative advantage, but the advantage is not obvious. Marine third industry does not have the phenomenon of industrial clusters, but with the potentiality of formation and development of industrial cluster. After the qualitative and quantitative analysis, the paper has a marine industry cluster development SWOT analysis for Shandong Peninsula Blue Economic Zone, and constructs development countermeasure matrix. Finally, based on the development of countermeasures matrix and combined with the marine industry cluster experience of United States, Australia and Japan, the paper proposes Shandong Peninsula Blue Economic Zone marine industry cluster development countermeasures from these aspects such as the ecological development of marine industry clusters, optimizing the structure of the marine industry cluster, supporting marine industry cluster based on modern technology and enhancing the government support and guide. |
