Using the Survey of Social Integration and Mental Health of Migrants in 2016 and housing price data, this article analyzes the characteristics and spatial pattern of housing ownership to discuss the structure, influencing factors and mechanisms of the housing class. The results show that the housing ownership of migrants forms the characteristics of non-agricultural hukou (household registration) and high-educated floating population occupying a large number of urban housing, showing a spatial pattern of differentiation along the “Hu Huanyong line”. China’s migrants has formed a “three-class five-level” housing class structure. Hukou and social security system still prevent the migrants from realizing the transition of housing class; some of them basically realize the accumulation of housing assets by relying on their personal socioeconomic conditions and mobility factors. System changes, urban scale, and urban-rural differences work together to intensify the differentiation of urban housing classes, and ultimately lead to the involution of the lower housing class and the accumulation of advantages of the upper housing class.

以住房分化视角, 利用2016年流动人口监测数据与房价数据, 分析流动人口住房占有的特征与空间格局, 住房阶层的结构及影响因素与机制。结果表明: 我国流动人口住房占有形成非农户籍、高学历流动人口大量占有城镇住房的特征, 呈现沿胡焕庸线分异的空间格局; 我国流动人口形成“三阶五层”的住房阶层结构; 户籍与社会保障的结构性因素仍然阻碍流动人口实现住房阶层跃迁; 部分流动人口凭借个人社会经济条件与流动要素等非结构性因素的作用, 基本上实现住房资产积累; 制度变迁、城市规模与城乡差异共同作用, 加剧城市住房阶层分化, 导致下层住房阶层流动人口内卷与上层住房阶层优势积累。
