Since2003, a series of issues are exposed gradually and increasingly inour housing market, such as the total imbalance, structural imbalance，the price out ofcontrol, and housing security has defect.As the stabilizer of the social development and the booster of the economicdevelopment, the housing problem of middle-income families has deep inference. It notonly related to the comprehensiveness and the effectiveness of housing policy andhousing security, but also related to the stability of the social development. Therefore, itshould attach great importance to the housing problem of the middle-income families.About whether urban middle-income families is facing housing affordabilityproblem, there are many inconsistencies in the research point of view, the criteria andthe scope of the traditional housing affordability measure, it caused conclusiondifferences. Therefore, in order to make the general public and related managementdepartments learned that the current level of housing affordability and its possiblechanges in real time, to build a system in line with China’s actual conditions and clearhousing affordability measure is necessary and compulsory. The main idea is: the properunderstanding of the premise of housing affordability connotation, analyzes theadvantages and disadvantages of traditional housing affordability measure method, andreveals the main factors affecting housing affordability.
