【摘要】 以区县尺度的人口流向为分析视角，从人口流入、人口流出和内部人口流动三个维度探讨2000—2020年中国人口流动的空间格局演变特征、作用机制与城镇化效应。研究结果表明：区县尺度的人口流入呈现集聚效应和分散化趋势，人口流出具有稳定的空间均衡化分布特征，内部人口流动表现出明显的区域差异。自然地理条件是形成中国人口流动不均衡格局的基础性因素，经济增长和就业机会增加是促进人口流动的核心驱动力，社会性因素对人口流动发挥着多元影响效应，省会城市市辖区对流动人口具有突出的吸引力。当前，人口流动对区县城镇化水平的提升作用已进入全国均衡的高贡献率阶段，内部人口流动是提升区县城镇化水平的核心动力。更多还原

【Abstract】 This study takes the population flow of municipal and county districts as the analytical perspective, aiming to explore the pattern evolutionary characteristics functional mechanism and urbanization effects of population flow, which across three dimensions: population inflow, population outflow, and internal population flow, within municipal and county districts in China from 2000 to 2020. The results show three conclusion: Firstly, in the municipal and county districts, the inflow of population exhibits clustering effects and a trend towards dispersion, while the outflow remains stable with spatially balanced distribution characteristics, and simultaneously internal population flow showing significant regional differences. Secondly, natural geographical conditions are the basic factors that form the uneven pattern of population flow in China, with economic growth and employment opportunities as the core driving forces to promote population flow. Social factors exert multiple influences on population flow, and the municipal districts of the provincial capital has a prominent attraction to population flow. Thirdly, the enhancement of urbanization levels which come of the contribution of population flow within municipal and county districts has reached a stage of high significance for national equilibrium. Internal population flow is the core driving force for improving the level of urbanization in municipal and county districts.更多还原
