- 摘要：
基于位置服务的人口迁徙数据能够直观、动态和详尽地描绘城乡居民日常活动的行为轨迹和时空特征。文章采用腾讯迁徙数据，通过时空统计和复杂网络方法分析泛珠三角地区人口流动的时空格局和结构特征。结果表明：泛珠三角地区人口日常流动的时空分异和层级鸿沟特征明显，春运期间总体呈现“S”型反向交互模式，各城市度中心性与所属层级高度耦合，时段演变趋势具有差分空间正相关关系，Ⅰ型、Ⅱ型城市度中心性及其波动幅度显著高于Ⅲ型、Ⅳ型；迁徙路线方面，省内流动呈现以省会城市为核心、周边城市为辅的“放射型”结构，跨省流动主要表现为以珠三角地区为核心的“扇形”结构，同时伴有“两横两纵”4 条高密度的迁徙走廊；结构均衡方面，Ⅰ型、Ⅱ型城市结构不均衡度较高，凭借强势的虹吸效应形成城市发展的外生驱动力，Ⅲ型、Ⅳ型城市结构不均衡度较低，与周边城市的共生性、对省会城市的依赖性较强，城市发展处于被极化的边缘位置。 - 关键词：

Based on the Tencent migration data, this article uses temporal-spatial statistics and complex network methods to explore the temporal-spatial pattern and structural characteristics of floating population in Pan Pearl River Delta region. The results show that: there are temporal-spatial differentiation and hierarchical gap in the daily population flow in the Pan Pearl River Delta region, which demonstrates a S-shaped pattern of reverse interaction during the Spring Festival travel rush. Degree centrality is highly coupling with hierarchy of cities, and its trend of changes exists a temporal-spatial differential autocorrelation. Degree centrality of type I and II cities are signifi cantly higher than type III and IV cities, and their range of fl uctuation is relatively higher. In terms of network structure, migration within the province presents an actinomorphous structure that take the provincial capital cities as a core. The interprovincial migration presents a fan-shaped radioactive structure that take the Pearl River Delta region as a core area which accompanied by two horizontal and vertical migration corridors. Cities of type I and II have a higher degree of structural unbalance, which forms an exogenous driving force for urban development by strong siphon; cities of type III and IV have a lower degree of structural imbalance, having strong symbiosis with surrounding cities and dependence with provincial capital cities, its development is on the edge of polarization.
