Analysis of the Characteristics and Evolution of Population Migration in the Countries along the Belt and Road Initiative
To explore the population migration characteristics and evolution patterns of BRI coun-tries,this paper constructs a network based on population migration data from 1960 to 2020 from the perspective of complex systems science,and conducts analysis by extracting backbone net-works,community divisions,and application of PageRank importance evaluation method.The results demonstrate that the migration volume of inflows and outflows within BRI countries has tended to be balanced,and the degree of openness is increasing year by year.And the migration process generally has"cohesion"and"aggregation".The influence of most BRI countries in the global network is higher than the world average.This study provides evidence and basis for the population policies of various countries.
