| Abstract: | Changing of region gravity center over time reflects dynamic evolution of spatial variation.This paper selects population,GDP,primary industry GDP,secondary industry GDP and tertiary industry GDP,s data of every country in Chongqing to calculate each gravity center by the model of region gravity center,and the dynamic evolution is to be analyzed.And the results show that:1) the distribution of population and economic is not balance in Chongqing,and spatial variation is from northwest to southwest;2) secondary industry and primary industry migrate vigorous and GDP and population remain steady;3)balance performances that:population>primary industry>GDP>tertiary industry>secondary industry,and distribution of them is gradually to be balanced;4) primary industry and tertiary industry are the main factors to influence the migration of the population. |
