Population flow pattern and urbanization effect in the municipal and county districts in China
China's population flow is undergoing all-round,multi-level,and diversified profound changes.This article takes municipal and county districts as the basic units,uses population flow as the analytical perspective,and discusses the evolution of population flow pattern and its urbanization effect in municipal and county districts from 2000 to 2020 from the three dimensions of population inflow,population outflow,and internal population flow.The research results reveal that:1)Population inflow is mainly concentrated in the four urban agglomerations of the Yangtze River Delta,Pearl River Delta,Beijing-Tianjin-Hebei,Chengdu and Chongqing,and provincial capital cities in the central and western regions,showing an obvious agglomeration effect.Population inflow has an increasingly obvious effect on improving the level of urbanization,especially in the eastern region.2)Population outflow is characterized by a stable spatial balanced distribution,and the scope of municipal districts and county districts with high intensity of population outflow continues to expand.Population outflow has played a positive role in simply improving the level of urbanization,but its negative effects,such as the imbalanced urbanization power structure and insufficient development potential in rural areas,cannot be ignored.3)The activity of internal population flow in the southeastern half of the"Hu Huanyong Line"is higher than that in the northwest half.The importance of internal population flow in the urbanization process has become increasingly prominent,and it has become the most important contributor to improving the urbanization level of municipal and county districts.
