随着我国城市化的快速发展，大城市的居住空间分异愈发明显，新生代流动人口的住房困难也成为亟待解决的社会问题。居住空间作为一种结构性不平等与流动青年的身份认同、归属感和居留意愿等主观心态之间存在深刻联系，本研究深入分析了居住空间与流动青年社会融入之间的关系，尝试回答了以下问题：大城市青年流动人口的居住分异现状如何？居住空间的哪些因素能够影响流动青年的社会融入，其具体作用机制是什么？流动青年又如何看待和应对住房这一结构性力量对他们日常生活的建构？ 研究发现，第一，流动青年的居住状态在不同住房类型、不同社会人口属性和不同地理区域之间呈现出较大差异，与自有住房青年相比，大城市租房流动青年的居住状况处于明显弱势地位。流动青年的整体融入度偏低，不同维度间存在较大差异，呈现不充分融入状态，住房产权、住房类型、社区环境、社区安全感等均对社会融入产生显著影响，租赁住房对租房群体的社会融入产生了削弱作用。第二，居住空间通过三条路径对社会融入发生影响，包括分配差异性的生活机会、提供互动情境并塑造社会互动模式、形成消费群体分化。第三，租赁住房通过四种机制削弱了租房青年的社会融入，包括心理上“临时性”的建构、社会互动中隔离的生产、产权文化的“符号暴力”和公共生活的阻断，导致了“悬浮的社会结构”的生成。第四，流动青年在住房的结构性制约下，依然能够发挥其主体性，通过话语的建构和威慑型维权等方式争取居住权利。 本研究在以往将住房作为财富或资本讨论的基础上加入了情境化理论、消费分层等视角，超越了单一的对住房产权的关注，论证了住房的空间、资本、互动、文化、政治等多维属性对个体施加的全面影响。此外，本研究还关切到了流动青年群体的能动性，增进了对弱势群体的居住权利和空间正义的理解。本研究也显示出，以住房自有率来衡量国民居住状态并不准确，应对居民现住房情况给予更多关注。

With the rapid urbanization in China, the increasing spatial differentiation of residential areas in large cities is becoming more evident, and the housing difficulties faced by the new generation of migrants have become an urgent social issue to be addressed. The residential space, as a form of structural inequality, has a profound connection with subjective mentalities such as identity recognition, sense of belonging, and willingness to stay among youth migrant population. This paper delves into the relationship between living space and the social integration of youth migrant population, attempting to answer the following questions: What is the current status of residential differentiation among young migrants in big cities? Which factors of residential space can affect the social integration of migrant youth, and what are the specific mechanisms? How do youth migrant population perceive and respond to housing as a structural force that constructs their daily lives? The paper finds out that, first, there are significant differences in the living conditions of youth migrant population among different housing types, social demographics, and geographical regions. Compared to young people who own their homes, youth renting in large cities are in a significantly disadvantaged position. The overall level of social integration of youth migrant population is relatively low, with substantial differences among different dimensions, indicating a state of incomplete integration. Factors such as homeownership, housing type, community environment, and sense of community security all have a significant impact on social integration, and rental housing weakens the social integration of the renting population. Second, residential space affects social integration through three pathways: the distribution of diverse life chances, the creation of interactive contexts and shaping social interaction patterns, and the division of consumer groups. Third, rental housing weakens the social integration of youth through four mechanisms: the psychological construction of "temporary" status, the production of social isolation, the "symbolic violence" of homeownership, and the hindrance of public participation, leading to the creation of a "suspended social structure." Fourth, despite the structural constraints of housing, youth migrant population are still able to assert their agency, striving for their right to housing through the construction of new discourses and threatening-like fights for housing rights. This paper goes beyond the previous discussions on housing as wealth or capital by incorporating the theories of contextualization and consumption stratification. It surpasses the overemphasis on homeownership and demonstrates the comprehensive influence of housing on individuals in terms of its spatial, capital, contextual, cultural, and political dimensions. Additionally, this study also focuses on the agency of youth migrant population, advancing the understanding of safeguarding the housing rights and spatial justice of disadvantaged groups. The paper also indicates that measuring the national housing situation solely by homeownership rate is not accurate, and more attention should be given to the current housing conditions of residents.
