Human capital plays an important role in promoting the development of Beijing’s economy. Tianjin and Hebei are close to Beijing，forming a “Great Capital Area.” Based on 1985-2010 “China Human Capital Panel Database”，we analyzed the human capital distribution in the “Great Capital Area.” Moreover，we discussed the relative magnitude between human capital and physical capital，as well as their relative efficiency in the economy. We also investigated the contribution of some important factors to the growth of human capital. Those factors include urbanization，education，aging and gender. This study will shed some lights on the human capital aspects for the proposed unification of three provinces/cities into the “Great Capital Area.”
