Abstract:Marine economy is increasingly becoming a new growth point for the economy of coastal countries and regions. The main body of marine economy is the marine enterprises and their various clusters. Based on the data from the Credit Zhejiang of more than 20 000 sea-based enterprises in Zhejiang coastal area, this paper applies nuclear density analysis, hot spot analysis, buffer zone analysis and proximity analysis to investigate the structure, spatial organization and evolution of marine enterprises in Zhejiang coastal area, so as to reveal the location features of the agglomeration and dispersal of marine industry in Zhejiang coastal area from a microscopic perspective. The findings are as follows:(1) The spatial distribution of marine enterprises in Zhejiang province shows obvious central agglomeration and external dispersion with a high degree of concentration. Among them, the convergence of the three rivers in Ningbo, the coastal area in the southwestern part of Zhoushan, and the urban area in Hangzhou form the core agglomeration area of marine enterprises while Jiaxing urban area, Wenzhou urban area, Taizhou urban area and Shaoxing urban area form 22 subordinate gathering areas; (2) The clustering characteristics of the major marine enterprises in Zhejiang show some differences in different types of marine enterprises. However, the municipal districts in Ningbo, Zhoushan and Hangzhou are the core agglomeration areas, while the other coastal cities in Zhejiang form sub-level agglomeration areas of different industries; (3) Zhejiang marine enterprises have shown obvious selectivity on location, that is, marine enterprises are distributed in the districts of coastline, industrial parks, ports and urban centers.
