摘　　要：中国春运是世界最大规模的人口迁徙,它所形成的网络结构、经济溢出及其距离衰减特征,对于理解中国城市群、都市圈的形成与发展具有重要意义。利用2019年春运高德迁徙大数据构建人口流动网络,分析中国城市人口流动网络结构特征,通过空间计量模型计算人口流动对城市经济溢出的影响,讨论溢出作用的距离衰减。结论如下:(1)中国城市人口流动网络呈现菱形结构,主要大城市对外控制与传播能力强。(2)中国城市人口流动与城市经济发展呈正相关,度中心性兼具促进城市自身经济发展与经济溢出作用。(3)城市间人口流动对经济溢出的影响存在距离限制,城市间距离500km内溢出显著,距离300~400km溢出较强。The Spring Festival travel season in China,known as"Chunyun",represents the world's largest human migration.The network structure,economic spillover effects,and distance decay characteristics formed during this period are crucial for comprehending the formation and development of China's urban agglomerations and metropolitan areas.This study utilizes 2019 Chunyun migration data from Gaude to construct a population mobility network,analyzing the structural characteristics of China's urban population mobility network.Using spatial econometric models,we calculate the impact of population mobility on urban economic spillovers and discuss the distance decay effect of these spillovers.The conclusions are as follows:(1)The urban population mobility network in China exhibits a diamond structure,with major cities demonstrating strong external control and dissemination capabilities.(2)There is a positive correlation between urban population mobility and urban economic development in China,where degree centrality promotes both urban economic growth and economic spillovers.(3)The impact of population mobility on urban economic spillovers has spatial boundaries,with significant spillovers occurring within 500 km between cities and stronger spillovers observed at distances of 300to 400km.
