摘要: 对于人口外流较少的地区,人口偏移量可以在一定程度上反映人口流动特征和程度。以云南省为典型案例,采用第六次全国 人口普查(以下简称“六普”)及第七次全国人口普查(以下简称“七普“)数据,通过偏移—分享模型展开人口空间集聚 特征及演变态势研究。研究表明:①云南省是典型的人口内部流动活跃省份,且人口呈现向部分地区集聚的态势。②州市尺度人口偏移呈现“极核迁徙”与“近域流动”并存的特征。昆明市始终是人口迁入的最大极核,而各州市内部逐渐出现集聚中心,吸引人口近域流动。③区县尺度人口集聚呈现多中心极核化态势,复杂的发展条件推动人口集聚核心呈极化态势,促使人口负偏移增长地区增多,加剧欠发达地区资源的不均衡分配。④未来云南省人口集聚的极核化趋势进一步发展的同时,旅游、边贸等支柱产业在疫情冲击下将导致人口集聚核心出现新变动,对人口空间布局和城镇结构体系提出新的要求。

Abstract: For areas with less external population migration, the amount of population growth shift can reflect the characteristics and degree of population migration to a certain extent. This paper looks into Yunnan Province by using the data of the sixth and seventh popularization census and shift-share analysis model. The research draws four conclusions. Yunnan Province is a typical province with active internal migration of population mobility and the population shows a trend of continuous agglomeration to some regions. At the city level, the population migration of Yunnan Province has two characteristics: 'polar nuclear migration' and 'near-regional mobility'. Kunming has always been the largest core of population immigration. At the same time, agglomeration centers have gradually emerged within each city, attracting the population to flow nearby. At the district and county levels, population agglomeration presents a trend of multi-center polarization. Complex development conditions promote the polarization of population agglomeration and increase the number of areas with negative population growth shifts which exacerbate the unbalanced distribution of resources in underdeveloped areas. In the future, while the trend of population agglomeration in Yunnan Province will further develop, pillar industries such as tourism and border trade will lead to new changes in the core of population agglomeration under the impact of the epidemic, which will put forward new requirements for the spatial distribution of the population and the urban structural system.
