Changes of spatial flow networks of African international students
Based on the data of international students'flow from 2000 to 2018,social network analysis and negative binomial regression model are used to analyses the change of spatial net-works of African students'flow and its influencing mechanism.The results show that:① The spatial flow of African international students always presents a"butterfly"spatial distribution pat-tern,with the north-south flow from Africa to Europe as the main path,and the expansion of Afri-ca to other continents as the secondary path.② The change of spatial flow network structure of African international students shows significant scale expansion and relative agglomeration.While the number of African international student increases significantly,the scale of internation-al African student among different countries has a hierarchical distribution gap.③ The nodes of spatial flow network of African international students always present a core-edge structure,and the spatial flow network is increasingly closely connected.The clustering characteristics of Afri-can international students flowing to core and sub-core nodes are becoming increasingly signifi-cant.④ Analysis of influencing factors shows that language proximity and historical colonial have the greatest influence on the choice of African international students,followed by the level of education in universities.In addition,agglomeration effect,trade connection,and geographi-cal distance have little influence,while the number of college students in host country,GDP dif-ference and per capita GDP difference have the least influence.
