“…Scholars have paid great attention to the research on the spatial behavior of population mobility and have made a lot of achievements in the macro pattern and micro location characteristics of population flow and the reasons for their appearance. In terms of theoretical research, laws of migration [3], push-pull theory [4], the gravity model [5,6], and the life cycle-mobility model [7] have been put forward; in terms of empirical research, scholars have conducted extensive case studies on the spatial pattern [8,9], characteristics [10,11], causes [12,13] and influencing factors [14][15][16][17], network complexity [18][19][20], relationship of the population migration and urbanization [21,22] with the regional economic development [23][24][25], population policy response and spatial planning strategy [26,27], and other areas.…”
