As a result, the relationship between migration trajectories and homeownership remains insufficiently understood. Based on the data from 2017 Chinese Migrant Dynamic Survey (CMDS), this study employs sequence analysis and generalized structural equation modeling to uncover how the spatiotemporal characteristics of different migrants evolve with age and the mechanisms through which migration trajectories influence migrants' homeownership. The analysis identifies six distinct types of migration trajectories based on their spatiotemporal features. The findings reveal that the direction of the initial migration is crucial: compared to those who migrate upward from the start, individuals who migrate at the same level are more likely to become homeowners. Moreover, migrants who begin their first migration at a later age are generally less likely to transition into homeownership. In addition to its direct effects, the migration trajectory also exerts indirect effects on homeownership via social integration and income levels. By framing migration as a trajectory rather than a static event, this study offers a novel lens for understanding migrants' access to homeownership. It highlights the importance of both spatial and temporal dimensions of migration and provides valuable implications for urban policy aimed at improving migrants' housing outcomes.\n"]
