Abstract: Human capital mobility is both related and different from the population mobility. Using the 2010-2016 national migrant dynamic monitoring data, this paper studies the phenomenon of human capital mobility caused by inter-provincial population movement in China from the perspective of direction and intensity. The results show that the net mobility direction of the population in each province is basically time-consistent，and in-migrant and out-migrant have stability. During the survey period，there were 16 provinces with a net out-migrant and 15 provinces with a net in-migrant，and the net mobility of human capital was completely consistent with the population mobility. However，the net mobility of inter-provincial population is not completely consistent with that of senior human capital. The net mobility of senior human capital in Shanxi，Guangxi，and Chongqing is always opposite to that of total human capital. The human capital mobility intensity was measured by the two indicators of out-migrant and in-migrant ratio and migration selection，and the results were basically the same. The central area of human capital mobility is more consistent with the distribution of population mobility. In 2010，the provinces with the highest human capital mobility intensity also had stronger mobility intensity in 2016，and the mobility intensity showed inertia and Matthew effect between provinces. The regions with the strongest human capital in-migrant include Beijing，Tianjin，Shanghai and other three municipalities directly under the Central Government and ethnic minority areas. The provinces with the strongest human capital out-migrant always include Anhui，Sichuan，Henan and other provinces. The human capital out-migrant elasticity measures the relative strength of human capital out-intensity and population out-intensity. The out-intensity of human capital in the eastern provinces and northeastern provinces is always greater than the population out-intensity，and the provinces in the western regions have large differences. In connection with the economic growth of the provinces in the past five years，the impact of population mobility or human capital mobility on economic growth is non-linear.
