Abstract: Drawing on the data from the latest three decennial censuses, this paper analyzes the spatial pattern and influencing factors of China's population change since 2000. The results show that China's population becomes more spatially unbalanced, which is reflected by the persistent difference between the east and west areas, the widening gap between the south and north areas, and the increasing disparity between the central cities and peripheral counties. Natural environment, economic, amenity factors and the administrative hierarchy play significant roles in population change. However, their effects not only evolve with time, but also vary among regions at different stages of development. In the last decade, regions with a high rate of population growth have transferred from the coastal areas to the inland areas and from the plain areas to the mountain areas. The differences of public services among regions become an important factor for population growths, especially in the east China. Central cities become more and more attractive to population, showing the increased impact of state forces, which mainly happens in the middle and west China. The results can help understand the driving factors of population change, and provide references for promoting the balanced population development.
