Abstract:

The regional marine economic development is closely related to the formation of spatial structure system of regional marine economy.Exploring the spatial structure of regional marine economy and proposing optimization strategy to enhance the comprehensive competitiveness of the regional marine economy have important significance.By using the combination of quantitative and qualitative methods,the study analyzed the spatial structure of marine economy of the Yangtze River Delta.,The results show that marine economic development is unevenly and the spatial layout is significantly different in the Yangtze River Delta.The spatial concentration situation of marine industries is obvious.The inverted pyramid marine economic spatial development zone has been developed.It takes Shanghai,Jiaxing,Hangzhou,Ningbo and Zhoushan as the center,Lianyungang,Yancheng and Nantong as the north axis,Taizhou and Wenzhou as the south axis.Based on this,some strategies are proposed.〖
