Abstract: Based on the CGSS 2018 survey data， regression analysis was applied to study the social class changes of the migrant population. It is found that: economic status is positively correlated with social class changes， and migration characteristics have differential effects on social class changes; mobile population class changes have significant regional heterogeneity， and social class changes are positively correlated with the disparity in economic development levels between regions; women with highly educated urban household registration are more likely to achieve social class leap through spatial migration. It is recommended to build an open urban social system， promote reasonable urban social class mobility， and cultivate civil society identity.

Key words: economic status; migration characteristics; social class; regression analysis
