Abstract:

Research on regional marine economy is the combination of regional economic theory with marine economic research as well as the regional economic theory applied to the marine economic research.It is considered as a global and cuttingedge theory and practical issue,meanwhile,developing the marine economy is also a hot issue around the world.With the development of marine economy,the connection between marine and land industry is strengthened.The single marine or basin area development mode has restricted the economic development,and the integrated industry has become a new trend.It can reach the ultimate goal of economic development through the planning,coordination,guidance and other means to improve the connection.Basin area,as a part of continent,is the most close to the ocean.Basin economy is a system of subregional economy based on the natural river system,with the distribution of resources as its core,such as manpower,financial resources and material resources.The linkage development of basin economy and marine economic is the premise to realize the integration of continent and sea.Based on the analysis of background,significance,basis and the effect of basin economy and marine economic linkage development,taking Yangtze River Economic Zones as an example,this paper quantitatively studied the connection degree of basin economy and marine economy by the grey relational analysis method.It pointed out that the marine first industry and the basin area third industry had the highest association,and followed by the basin area second and first correlation.The marine second industry and basin area third correlation roughly equalled.The marine third industry was most closely connected the basin area first industry.At the same time the paper calculated the relevancy between the main marine industry and the basin area three industries.Finally,some suggestions,such as making a unified plan for basin area and sea,implementing the strategy of invigorating the sea through science and education,protecting the marine ecological environment,organizing guarantee and innovating mechanisms,policy supporting,legal system building were put forward to promote the linkage development of basin economy and marine economy.
