【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。
[Abstract]:With the development of urban economy and the rapid development of urbanization, the spatial pattern of population migration has changed greatly. Based on the data of the national inter-provincial migration matrix from 1985 to 2015, this paper discusses the overall characteristics of the interprovincial population migration network and the role of each node in the network by using the social network analysis method. The results show that the density of interprovincial population migration network experienced a slow decline from 1985 to 2000 and a continuous rising process from 2000 to 2015. The inward center potential of the population migration network is obviously larger than that of the outward center potential, which indicates that the population migration places are relatively concentrated, which is closely related to the development mainstream of the main population migration areas in the southwest and the central part of the region, which is closely related to the development mainstream. The interprovincial population migration network can be divided into five subgroups: northeast-north china population linkage region, central Plains-Yangtze river delta population linkage area, central south-south china population linkage area and northwest population linkage area Among them, the central Plains-Yangtze River Delta population linkage region is the region with the closest connection within and among the groups; the central south and south China population linkage region is the region with the highest cumulative migration volume in the whole country; the northeast-north China population linkage region has strong internal links. Based on central analysis and core-marginal structure division, the contribution of provinces (cities and districts) to the population migration network is different. Guangdong and Beijing have global control significance. Shaanxi, Sichuan, Zhejiang are basically in the core node sequence, Shanghai, Tianjin, Inner Mongolia, Fujian gradually strengthen the core role, Henan, Hubei, Hebei, Xinjiang, the core role of the decline, the overall migration path northward.
