摘要
随着中国城市经济的发展以及城镇化的快速推进,人口迁移的空间格局发生了重大变化。本文基于1985-2015年全国省际人口迁移矩阵数据,运用社会网络分析方法,探讨中国省际人口迁移网络的整体特征以及每个节点在网络中的地位作用。研究结论为:(1)省际人口迁移网络密度经历了1985-2000年的缓慢下降、2000-2015年持续上升的过程,与西北、西南和中部主要人口迁出地向东部经济发达地区的集中性迁移成为发展主流密切相关。(2)人口迁移网络的内向中心势明显大于外向中心势,说明人口迁入地相对集中,人口迁出地相对分散。(3)省际人口迁移网络可分为东北—华北人口联动区、中原—长三角人口联动区、中南—华南人口联动区、西南人口联动区、西北人口联动区5个子群。其中,中原—长三角人口联动区是群内和群间联系最紧密的区域;中南—华南人口联动区是全国人口累计迁移量最高的区域;东北—华北人口联动区内部联系较强,对外仅与西北人口联动区联系较强。(4)基于中心性分析以及核心—边缘结构划分,各省(市、区)对于人口迁移网络的贡献意义不同,广东、北京具有全局控制意义,江苏、陕西、四川、浙江基本处于核心节点序列,上海、天津、内蒙古、福建核心作用逐渐增强,河南、湖北、河北、新疆核心作用出现下降,全国人口迁移路径总体向北偏移。
With the rapid development of urban economy and the promotion of urbanization, great changes have taken place in the spatial pattern of population migration in China. Migration has played an important role in the economic, social, and cultural development of cities. Based on the provincial population migration matrix data of31 provinces, autonomous regions, and municipalities in 1985-2015, a social network analysis was conducted to investigate the overall characteristics of interprovincial population migration network and the role of each node.The results show that：（1） Network density of interprovincial population migration has experienced a slow decline in 1985-2000 and a continuous increase in 2000-2015. The concentrated migration of population from the northwest, southwest, and central regions to the eastern developed areas has become the mainstream of development.（2） The inward center potential of population migration network rapidly increased in 1985-2005 and gradually declined in 2005-2015. It indicates that the number of important population moving areas were increasing gradually（such as Tianjin and Fujian）, towards a ＂multi-polarization＂ development. The outward center potential was always at a low level and exhibited a trend of fluctuation. The inward center potential was clearly larger than the outward center potential. It indicates that the population migration area is relatively concentrated, and the population emigration area is relatively dispersed.（3） The interprovincial population migration network can be divided into 5 groups： Northeast-North China population linkage area, Central PlainsYangtze River Delta population linkage area, Middle South-Pearl River Delta population linkage area, southwest population linkage area, and northwest population linkage area. Among them, the Central Plains-Yangtze River Delta population linkage area was the most closely linked between and within group; Middle South-Pearl River Delta population linkage area had the highest total population m
