本文選題：春運 + 人口流動��； 參考：《人口研究》2017年03期

【摘要】：文章基于百度遷徙數(shù)據(jù)構(gòu)建人口流動的關(guān)系矩陣,完整刻畫出2015年春運期間全國人口在東部與中西部城市間省際循環(huán)流動的空間集聚與擴散過程。主要研究結(jié)論:(1)2015年2月13日(臘月廿五)至17日(臘月廿九)和2月25日(正月初七)至3月1日(正月十一)是春節(jié)前返鄉(xiāng)流和節(jié)后返工流兩階段人口凈流入(流出)的峰值時段,兩階段各市日人口凈流入人次存在正負對應(yīng)的規(guī)律性特征;(2)人口省際流動的近域特征、空間依賴關(guān)系并存,京津冀、長三角、珠三角城市群主導(dǎo)了高強度人口流動,并形成3個扇形輻射區(qū)域;(3)識別出全國94個人口流入城市和242個流出城市。在空間上,人口集聚的沿海綿延帶與人口流失的中部塌陷帶共同構(gòu)成流入、流出城市的雙縱平行格局。
[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.
