中国海洋产业发展的地区差距变动及空间集聚分析

采用基尼系数、变异系数、加权变异系数等指标,分析了20世纪90年代海洋经济发展的地区差距以及海洋产业空间集聚的变动趋势。得出以下结论,90年代前半期,我国海洋经济的相对地区差距缩小,后半期有所扩大。90年代多种海洋产业在同一地区的空间集聚减弱。其中,1995年到2000年多种海洋产业的空间集聚加剧。我国海洋经济地区差异与多种海洋产业的同一空间集聚表现为相同的变动过程。

Changes of regional differences and zonal centralizations of marine industry in China in the 1990s

The paper adopt indexes of Geordie coefficient, Variation coefficient and Power variation coefficient to analyze the trends of regional differences of marine economy and zonal centralizations of marine industry in China in the 1990s Then the following conclusions were drawn 1)The regional differences of marine economy decreased from the year 1990 to 1995, while the differences increased correspondingly from 1996 to 2000 in China 2)The speed of zonal centralizations of multiple marine industries was very slow in the same areas of China in the 1990s But zonal centralizations of some marine industries became strong from 1995 to 2000 3)The changing process of regional differences of marine economy is the same as that of spatial centralizations of multiple marine industries Regional differences of marine economy decreased from 1990 to 1995, and the changing speeds of spatial centralizations of multiple marine industries became slow in the early 1990s While changing trends of the above two indexes in the late 1990s were different from that in the early 1990s 4)The important approach of reducing regional differences of marine economy is building up the zonal moving capacity of marine industries On the one hand, economic benefits of enterprises should be increased On the other hand, zonal moving cost of enterprises should be decreased
