Study On The Network Structrure Of Population Flow In Beijing,Tianjin And Hebei And Its Influence On Economic Development

Since the reform and opening up,China has been vigorously developing the urban and rural economy while promoting the continuous reform of the household registration system,which has led to the phenomenon of large-scale population mobility.Population,as one of the factors of production,will have a direct impact on economic development.The coordinated development of regional economy has become a national strategy.At this time,it is of great significance to study the network structure of population mobility in Beijing-Tianjin-Hebei region and its role in regional economic development.This paper first introduces the topic selection background and research significance of this paper,and then explains and discriminates the concept of population flow and migration,and then sorts out relevant theories of population flow,and its evolution process,and then reviews the research methods and ideas of domestic and foreign scholars on population flow,and analyzes and summarizes the research results of scholars.According to the research content and the actual situation of this paper,the research method of social network is finally determined.Secondly,the population distribution and flow status in Beijing-Tianjin-Hebei region are analyzed from two aspects of section and time,so as to grasp the overall situation of Beijing-Tianjin-Hebei population.Then,the net floating population of the Beijing-Tianjin-Hebei region is calculated according to the urban statistical yearbook data over the years,and the social network of the population flow is constructed to analyze the structural characteristics of the network and its evolution trend.Finally,the network structure indicators in the population flow network were selected to be included in the framework of social and economic development,and the production function was combined to construct the QAP regression model to empirically test the impact of population flow on economic development.The study found that the population distribution in the Beijing-Tianjin-Hebei region is not balanced,and the population density in Beijing and Tianjin is much higher than other cities in the region Beijing and Tianjin account for nearly half of the floating population in the region,and as a popular choice of the floating population Beijing and Tianjin occupy the core position of the population flow network,which is the core node of the population flow network.In terms of time,the overall network structure is increasingly stable,the population flow is no longer excessively concentrated,and the population distribution in Beijing,Tianjin and Hebei region is developing in a balanced way.There is a strong cohesion among the cities in the Beijing-Tianjin-Hebei region.There is a close relationship established by population flow,and the speed and efficiency of population flow are very high.Finally the model verifies that occupying the "structure hole"position in the network does have a positive impact on economic development.
