摘　　要：人口迁移已成为各个国家或地区之间频繁发生的交互现象,人口迁移网络研究是社会网络与复杂网络的重要应用领域。首先以全球人口迁移数据为基础,以国家或地区为节点,以国家或地区之间的人口迁移为边构建网络;然后研究全球人口移动网络的结构探测与时空分析方法,探索全球人口迁移网络的结构特点和时空变化规律。研究结果表明,全球人口迁移网络具有无标度、小世界与异配等特性,其网络结构的变化与地理位置、国际关系、国际事件紧密相关。研究结果对于全球尺度的人口问题研究具有一定的参考价值。Population migration has become a frequent interaction phenomenon among countries or regions,and the study of population migration network is an important application field of social network and complex network.Firstly,based on the global population migration data,we constructed a network with countries or regions as nodes and population migration between countries or regions as edges.Then,we studied the structure detection and spatio-temporal analysis methods of global population migration network,and explored the structural characteristics and spatio-temporal change rules of global population migration network.The results show that the global migration network has the characteristics of scale-free,small-world and heteropogy,and the changes of network structure are closely related to geographical location,international relations and international events.This study has certain reference value for the study of population problems at global scale.
