论文摘要
中国的人口变化具有重要的全球经济和地缘政治意义。但是,由于由行政边界调整引起的人口普查数据的空间不一致,我们对微空间量表的这种转变的理解仍然有限。为了填补这一空白,我们从2010年至2020年在该县和县城城市级别手动收集并建立了人口普查小组。我们表明,大规模的内部迁移推动了中国的人口集中度和区域差异的增加,导致城市缩小城市的人口衰老,并增加了不断增长的城市的性别失衡。
China's demographic changes have important global economic and geopolitical implications. Yet, our understanding of such transitions at the micro-spatial scale remains limited due to spatial inconsistency of the census data caused by administrative boundary adjustments. To fill this gap, we manually collected and built a population census panel from 2010 to 2020 at both the county and prefectural-city levels. We show that the massive internal migration drives China's increasing population concentration and regional disparity, resulting in severe population aging in shrinking cities and increasing gender imbalance in growing cities.
