County-Scale Migration Attractivity and Factors Analysis

To study migration at county scale and measurement of destination attractivity accurately can reveal the migration flows in more details and explain what kinds of county have higher attractivity ability that will help local governors make better policies to enhance county attractivity and attract more migrants for regional development. The county-scale relative intrinsic attractivity (RIA) of Guangdong Province is computed by using the number of migration and the corresponding distance. The results show that there is an obvious distance decay phenomenon on RIA. The closer to destination, the more migrants move to destination. Moreover, the RIAs have higher correlation relation with migrants to destination. The RIA appears as core-periphery belt pattern. The center of Pearl River Delta is the RIA high core, and the outside areas of the delta are the low RIA belt. The RIA spatial difference is determined by economic factors, living standards and population quality.
