Abstract: Unbalanced regional development can be examined by looking at the mismatch between demographic distribution and economic distribution across the regions Using the indicators measuring the degree of mismatch between demographic and economic distribution of the regions in China，this paper revisits the disparities and their changes in regional development，identifying a converging trend in the regional differences after 2003. By decomposing the regional differences into contributions of demographic and economic concentrations，this paper also explores the mechanisms of changing regional differences，and concludes that the changes of regional differences are more attributable to the effects of economic gathering than to those of demographic gathering Demographic concentration is playing an increasingly important role in reducing the regional differences with reducing barriers to population mobility The paper also discusses policy approaches addressing balanced regional development in China.
