Abstract: Using population census data and spatial analysis method, this paper examines the influencing factors of China's inter-provincial migration over 2010~2020. Inter-provincial floating population in China expands enormously, and presents an unbalanced “twoway floating” pattern. Interprovincial floating population is dominated by migration from the less developed provinces in the central and western regions to the more developed provinces in the East and adjacent regions. Factor analysis and geographically weighted regression model are used to explore factors affecting China's inter-provincial migration. While economic and social factors have significant impacts on inter-provincial migration, the impacts are greater in the central and eastern provinces than in the western provinces. The East-West gap in the impact of economic and social factors on net migration is still considerable, and the North-South gap is on the increase.
