Abstract: Based on the data from the sixth census in 2010, this paper analyzes the migration patterns of population in urban agglomerations, while using the Gini algorithm measures the equilibrium of population and economic in urban agglomerations before and after migration. The study shows the following findings. Firstly, the scale of migration is large in urban agglomerations, population inflows and outflows show a central tendency, especially the inflows concentration. Secondly, the distribution of migration presented the feature of polarization and localization. The urban agglomerations in the east are the main inflow area. The population inflows and outflows are coexisted in the east urban agglomerations where the most of Inflows population come from other provinces. Thirdly, the Pearl River Delta urban agglomeration is still the most important center of inflows population. The Jianghuai and the Ring of Boyanghu urban agglomeration are the center of outflow s population. Fourthly, the equilibrium of population and economic development of the urban agglomerations is reasonable. The difference between the equilibrium in agglomerations is significant but there was no obvious regional differentiation. The population migration significantly improved the equilibrium of population and economic in urban agglomerations.
