Daily Population Flow Network and Its Structural Characteristics in the Beijing-Tianjin-Hebei Region
By combining the methods of geospatial analysis and social network analysis,the paper analyzes the in-tensity and network characteristics of the intercity and outbound population flow of cities in the Beijing-Tianjin-Hebei region from Tencent location-based big data in 2018.Results show that the outbound migration of major cit-ies in the region under study presents an apparently hierarchical distribution pattern.City size or traffic influence has a strong correlation to the intensity of connections with Beijing.For those second-tier cities,proximity is the biggest contributor.A city's outbound population flow by car is significantly affected by the proximity principle,while the mode of outbound population flow by plane or by train is more governed by the economy.Cities in the region are closely connected with national economic centers and transportation hubs by means of planes and trains.The population flow network forms a large urban agglomeration in the northern part of the region plus three small ones in its southeast,with Beijing,Langfang,and Tianjin being the core of regional population migra-tion network,and the triangle region formed by Beijing,Tianjin,and Shijiazhuang being the core area of popula-tion flow.
