Taking the conception and model of the regional gravity center and adopts production value of population, GDP, industry, agriculture and the tertiary industry and data of expenditure in recent eleven years in every city, and figures out the coordinate of gravity center of each year. This paper calculates the population gravity center and the social economy gravity center yearly, figures out the dynamic evolvements of these two gravity centers and analyzes the dynamic change of the population and economy regional differences and their related causes and at the same time, makes a contrastive analysis of the dynamic evolvement tendencies of the two gravity centers. From the developing evolvement of gravity center we can draw a conclusion:(1) The population gravity center first slowly moves to southwest and relatively fast move to northeast after the year 2003 in recent eleven years. (2)There are significant regional differences in economic development and living standards.
