【摘要】：文章基于百度迁徙数据构建人口流动的关系矩阵,完整刻画出2015年春运期间全国人口在东部与中西部城市间省际循环流动的空间集聚与扩散过程。主要研究结论:(1)2015年2月13日(腊月廿五)至17日(腊月廿九)和2月25日(正月初七)至3月1日(正月十一)是春节前返乡流和节后返工流两阶段人口净流入(流出)的峰值时段,两阶段各市日人口净流入人次存在正负对应的规律性特征;(2)人口省际流动的近域特征、空间依赖关系并存,京津冀、长三角、珠三角城市群主导了高强度人口流动,并形成3个扇形辐射区域;(3)识别出全国94个人口流入城市和242个流出城市。在空间上,人口集聚的沿海绵延带与人口流失的中部塌陷带共同构成流入、流出城市的双纵平行格局。
[Abstract]:Based on Baidu migration data, this paper constructs the relationship matrix of population flow, and describes the spatial concentration and diffusion process of the circulation of population in the east and the central and western provinces during the Spring Festival in 2015. Main conclusions: February 13 (December 25) to 17 (December 29) and February 25 (first month 7) to March 1 (January 11) are the two stages of net inflow of population before the Spring Festival and after the Spring Festival. Peak period (outflow), There are positive and negative regular characteristics of daily net inflow of population in each city in the two stages. (2) the characteristics of interprovincial population flow are close to each other, and spatial dependence exists. The urban agglomeration of Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta dominates the high-intensity population flow. Three fan-shaped radiative regions were formed, and 94 population inflow and 242 outflow cities in China were identified. In space, the contiguous coastal belt of population concentration and the central collapse zone of population loss constitute the double longitudinal parallel pattern of flowing out of the city.
