Abstract: As the quantitative demographic dividend is diminishing, improving labor quality and individual human capital become the key to maintain the highquality development of China's economy. In addition to increasing labor supply, population agglomeration is an efficient way of improving individual human capital through the mechanisms of knowledge spillover and employment competition. Based on the theoretical model of urban individual human capital and population agglomeration, this paper empirically examines the impact of population agglomeration on individual human capital using Chinese provincial data from 2000 to 2015. Population agglomeration could significantly improve urban individual human capital, in a sense that a higher degree of population agglomeration is associated with a larger effect on individual human capital. These findings are consistent with the agglomerative economics theory. The results of panel threshold regression show that the effect of population agglomeration on individual human capital could be significantly enhanced when knowledge spillover and employment competition exceed the threshold value.
