摘要:

基于街道/乡镇尺度人口普查数据,利用GIS空间分析和数理统计方法,从规模、占比、密度和集聚度等4个层面分析北京城区流动人口扩散特征,并揭示其驱动机制。研究发现, 2000~2010年北京城区流动人口规模和密度增加,但流动人口占常住总人口比重和流动人口空间集聚度下降,流动人口呈现明显的空间扩散态势。 北京城区流动人口呈“核-边扩散”格局,城市核心区流动人口规模、密度、占比和空间集聚度不断下降,城市边缘区流动人口规模、密度、占比和空间集聚度逐步上升。 北京城区流动人口的“核-边扩散”格局是经济因素的直接推动、城建因素的间接推动、交通因素的硬性诱导、制度因素的软性诱导等共同作用的结果。

Abstract:

Based on the population census data at the subdistrict/town scale, taking Beijing Metropolitan area as the study area, employing the population density model, Getis-Ord G index and spatial econometrics model, this article analyzes the spatial sprawl pattern of the floating population from the four aspects: size, proportion, density and clustering. Then this article explores the driving forces and their influencing mechanism for the spatial sprawl pattern of the floating population. The results show that: firstly, the size and density of the floating population showed a clear growth trend of up to 18% in Beijing Metropolitan Area in 2000-2010; however, the proportion and the clustering degree of the floating populating showed an obviously declining trend. Secondly, the floating population experienced 'core-periphery sprawl' pattern in 2000-2010. The implication is that the floating population was relocating from the urban core areas to the urban periphery areas during the decade. The size, density, proportion and clustering degree of the floating population was continuously declining in the urban core areas; meanwhile, the size, density, proportion and clustering degree of the floating population was increasingly inclining in the urban periphery areas. Thirdly, the result of the spatial ecometrics model shows that the 'core-periphery sprawl' pattern of the floating population was the aggregated outcomes of the economic factor (represented by the housing cost and the employment opportunity), the urban construction factor (represented by the proportion of rural housing land) , the transportation factor (represented by the distance to the nearest subway station and the density of bus stations) and the institutional factor (represented by the percent of the registered agricultural population). The direct driving force was that the housing affordability of the floating population cannot keep up with the pace of the increase of the housing rent. The indirect driving force was the demolition of low-income floating population residing communities including the 'villages in the city' and the squatter settlements. The hard attractiveness force was the huge improvement of the public transportation accessibility in the urban periphery areas. The soft attractiveness force was the special urban-rural dualism in China.

Key words: floating population, 'core-periphery sprawl' pattern, Beijing Metropolitan Area
