The construction of affordable housing is not only housing construction，but also community cultivation. The construction of affordable housing community is one of the key indicators to determine the effectiveness of the housing policy. Based on collecting related literature in CNKI, the researcher conducts a quantitative analysis of the research literature on affordable housing in China by using Bicomb2.0. The study has found that the quantity of research results is closely related to the development of the policy. The research focuses on the housing policy, financing and post management. Community research is marginalized in the research heat maps, and research disciplines are mostly human geography, management and so on. Then the researcher reviews the four core issues in the study of affordable housing community, such as the spatial location and community segregation of affordable housing, the satisfaction and influencing factors of housing community, the neighborhood interaction and social integration of affordable housing community and public service and community governance of security housing community. Finally, the paper provides proposals for future study.
