摘要:

基于卫计委发布的2017年全国流动人口动态监测调查数据,系统分析了川渝地区流动人口空间格局与流动网络。研究发现,1)在流动人口数量变化上,川渝地区区际流出人口规模依然较大,2010年以来出现一定程度的人口回流;同时,区内流动人口规模开始超过区际流动,成为人口流动的主要方式,体现出当前川渝地区对人口的凝聚力进一步提高。2)流动人口空间分布方面,区际流出人口主要来源于川渝东北部县级单元,区际流入主要来源于川渝周边临近省份。区际流出主要方向为东部沿海城市群和地域邻近的西南各省,区际流入主要方向为成渝主城。区内流动以川渝中间塌陷带流向成渝双城经济中心为主要趋势,重庆以主城为单核心吸引人口;四川以成都主城为大核心,攀枝花、宜宾城区为小核心吸引人口。3)川渝人口流动网络集中在川渝中部地区,以省市内的人口短途流动为主,形成以成渝双城区为核心的“双核心+边缘”空间格局,两核心及区域之间的人口流动联系较弱,行政界线对川渝地区的人口流动影响依然较大。

Abstract:

Population flow is an important component of regional spatial network, but there are few empirical studies on its quantity and spatial pattern in outflow areas in extant literature. The development of the population flow pattern since 2010 has important theoretical contributions to the understanding of the population flow pattern and mechanism in modern China. Based on the Migrants Dynamic Survey of China's floating population by the National Health Commission, PRC, in 2017, this study systematically analyzed the spatial pattern and mobile network of the floating population in Sichuan-Chongqing, one of the most important outflow areas in China. The study found that the scale of the interregional outflow in this area is still large in terms of floating population. However, there has been a certain degree of population backflow since 2010 and the floating population has begun to surpass interregional mobility, which shows that Sichuan-Chongqing is increasingly attracting population. In terms of the spatial distribution pattern of floating population, the outflow to other provinces is mainly from the county units in the northeastern part of Sichuan-Chongqing and the inflow is mainly from the neighboring provinces of Sichuan-Chongqing. Further, the outflow to urban agglomerations is mainly toward the eastern coastal regions and the neighboring provinces in southwest China, whereas the inflow is toward the urban areas of Chengdu and Chongqing. Overall, the population flow here is mainly toward the urban center in both Chengdu and Chongqing. The areas that attract the utmost population flow are as follows, in order: the urban area of Chongqing; the urban area of Chengdu, which is a center for Sichuan; and the urban areas of Panzhihua and Yibin. The distribution of the population flow is highly concentrated in the central region of Sichuan-Chongqing, which shows a spatial pattern of "core-periphery." Short-distance population flow dominates the mobility network in this region. Further, the core of Chongqing urban area is closely connected with not only most districts and counties in the city but also Guang'an City and Nanchong City, Sichuan Province, whereas the core of Chengdu urban area is closely connected with the Chengdu Plain Economic Zone. Cities located along the border of Sichuan and Chongqing, such as Zigong, Yibin, Ziyang, Neijiang, and Dazhou, are greatly influenced by the cores of both Chengdu and Chongqing, and the population flow network is comparatively complex. The population flow between the two cores is weak. This shows that the administrative boundary between Chongqing and Sichuan has a significant influence on the population flow in this area.
