我国三大经济区海洋经济时空差异探讨

本文以我国陆域三大经济区为空间尺度划分海洋经济区域,在采用变差系数和泰尔指数定量分析海洋经济省际差异的基础上．运用泰尔指数对三大经济区海洋经济总体差异进行区际结构分解．比较环渤海、长三角和珠三角经济区内部海洋经济差异及区际差异,探究海洋经济差异的内部机理。并运用基尼系数分析三大区产业结构的演进过程。最后,总结我国三大经济区海洋经济差异的动力机制。

Research on the Disparities of Space and Time of Marine Economy of the Three Economic Zones in China

In order to keep the economic of marine-land consistent, marine economic zones are divided into three regions according to land in this paper （Yangtze Delta Region, Pearl River Delta Region, Bohai-sea＇s Coastal Region）. Based on the difference of marine economy of the provinces, this paper uses the methods of coefficient of variation and Theil entropy to analyze the characteristics of dynamic variation of industrial structure of 1996-2004. Then it decomposes the formations of regional marine economic disparities and find that the regional difference of marine economy is due to the difference inside the regions mostly, especially in Bohai-sea＇s Coastal Region. ln addition, the article uses Gini index to analyze the evolution process and characteristics of marine industrial structure in the three economic zones. At last, it explores the function and driving mechanisms of the difference of marine economy in China.
