【摘要】：本文通過構建人口省際流動的關系矩陣,透視2015年中國春節(jié)期間人口省際流動的動態(tài)過程、網(wǎng)絡特征,并對各省人口流入、流出的規(guī)模差異進行測度。研究結論如下:(1)春節(jié)前后中國各省每日人口凈流入人次存在顯著的規(guī)律性特征,2月13-17日和2月25日-3月1日為各省節(jié)前返鄉(xiāng)流和節(jié)后返工流期間人口凈流入、流出峰值時段,可作為基于春運研究中國人口省際流動的重要依據(jù);(2)識別了14個人口凈流入省、17個人口凈流出省,凈流入位序前六省和后八省分別吸納和提供了全國9成人口的集聚與擴散。人口主要流入省的沿海綿延和主要流出省的中部"人口塌陷"共同構成了雙縱格局;(3)各省流出首位流的指向特征顯著,南方人口流出省的流出指向存在共性,京津、長三角、珠三角地區(qū)的人口集聚路徑存在差異。(4)移動數(shù)據(jù)為發(fā)掘人口流動過程中蘊含的豐富信息提供了平臺,基于節(jié)后、節(jié)前凈流入值差值的方法可以有效識別中國人口流動的規(guī)模差異、屬性特征。通過與以往研究對比,證實了移動數(shù)據(jù)與基于人口普查數(shù)據(jù)研究的諸多結論相似性。
[Abstract]:By constructing the relationship matrix of population flow between provinces, this paper analyzes the dynamic process and network characteristics of the population flow between provinces during the Spring Festival of 2015 in China, and measures the scale difference of the inflow and outflow of population in each province.The results are as follows: (1) before and after the Spring Festival, there are significant regular characteristics of the daily net inflow of the population in every province in China. February 13-17 and February 25-March 1 are the periods of net inflow and outflow of population during the period of returning home before and after the Spring Festival.As an important basis for the study of interprovincial population mobility in China based on Spring Festival Transportation, 14 provinces with net population inflow and 17 provinces with net population outflow are identified. The first six provinces in order of net inflow and the last eight provinces respectively absorb and provide the concentration and diffusion of 90% of the population in the whole country.The coastal extension of the main inflow of population into the province and the "population collapse" in the central part of the main outflow province together constitute a dual longitudinal pattern. (3) the directional characteristics of the first outflow of the provinces are significant, and the outflow direction of the southern provinces has a common character, namely, Beijing, Tianjin, and the Yangtze River Delta.The migration data in Pearl River Delta provide a platform for discovering the rich information contained in the process of population flow.The method of difference of net inflow value before the festival can effectively identify the scale difference and attribute characteristics of population flow in China.By comparing with the previous studies, the similarities between mobile data and census data are confirmed.
