After the housing marketization reform，the division of housing resource among the different youth groups becomes increasingly expanding using the data of Chinese Family Panel Studies（CFPS 2010），this paper analyzes the mechanism of housing inequality among the youth.The research shows that both market and redistribution system have lead to the division of housing resource：the youth who are more educated own larger residential space，which means that the rewarding of investment of human capital to young people when they obtain housing resource is increasing in the market economy；Meanwhile，working in Party and government organizations are also conducive to the ownership of larger residential space，indicating that the effects of redistributive power on housing resource still exist.Both professional elites and political elites have derived benefits from the housing marketization reform，however，the gap of the housing resource between the elites and non-elites is severely widening.
