SPATIAL PATTERN OF CHINA'S POPULATION URBANIZATION FROM THE PERSPECTIVE OF POPULATION MIGRATION:A STUDY BASED ON BAIDU MIGRATION DATA
This paper measures the spatial pattern of China's population urbanization formed by population migration in the process of urbanization by using Baidu Migration Data.Selecting Baidu Migration Data of two periods,i.e.,before the Spring Festival and ordinary days,and using prefecture-level cities as spatial units,the paper analyzes the spatial pattern characteristics and influencing factors by obtaining the distribution and migration direction of the migrant population after comparing the characteristics of intercity travel between the period before the Spring Festival and ordinary days,and using local spatial autocorrelation and other methods.It is found that China's population urbanization has formed a spatial pattern of north-south differentiation from the perspective of population migration.Southern China is the high-value clustering region for migrant population,and northern China is the low-value clustering region.The LISA(Local Indicators of Spatial Association)results show a north-south differentiation that is basically consistent with the"Qinling-Huaihe Line",which is obviously different from China's socioeconomic spatial distribution characteristics of eastern,central,and western regions.The phenomenon of north-south differentiation in population urbanization is related to the differences in the impacts of the three urban agglomerations,which are the Yangtze River Delta,the Pearl River Delta,and Beijing-Tianjin-Hebei Region,as well as the differences in the intra-provincial urbanization process between the north and south regions.The pattern of prefecture-level cities in southern China is driven by large-scale inter-provincial urbanization in which the population is migrated to the three major urban agglomerations,along with intra-provincial urbanization in which the population is migrated to provincial capital cities.The pattern of prefecture-level cities in northern China is a result of both weakened inter-provincial urbanization in which the population is migrated to the three urban agglomerations and weakened intra-provincial urbanization in which the population is migrated to provincial capital cities.
