英文摘要：

This paper explores the methods for studying regional economic disparities in the aspects of research unit being chosen and measurement index being used on the basis of the analysis of the studies on regional economic disparities at home and abroad. It takes output value of marine industries per capita as an index for measuring regional marine economic disparities and 11 coastal provinces and municipalities in China as basic regional study units. It divides the 11 coastal provinces into three regions（the northern, central and southern regions）, and uses Gini index and Theil index as quantitative methods to demonstrate the total level of Chinese marine economic sdisparities and the characteristics of dynamic variation of industrial structure of 1996～2005. Then it decomposes the formations of regional marine economic disparities. Finally it analyses the cause of formation and function mechanisms. The main conclusions are： （1）In the late 1990s, Chinese total marine economic diaparity decreased sharply and in the early 21st century it inceases gradually, with fluctuations appearing in several years. The intra-regional disparities mainly devote to the overall disparities. What is more,the intra-regional diaparities of the central region make the greatest contributions with the greatest flutuations. （2）The agglomeration level of specific resources and coastal tourism are the biggest, and that of general resource is the smallest. The development of the second marine industry is a little weak. And the temporal change of marine industrial structure is different from land industrial structure. （3） The causes of formation are historical basis, economic developing level, resource endowment, regional development policy,changes of foreign investment and the level of the drivig force of central cities in the regions. Spatial agglomeration of industry is the dynamic mechanism for regional disparities.
