Although previous investigations have agreed that Chinese rural-to-urban migrants’ socioeconomic status (SES) increases with their migration, the association between SES and subjective well-being is uncertain. To address this research gap, the present study proposed that the association between objective SES and subjective well-being is mediated by subjective SES. This model was tested with a sample of 432 Chinese rural-to-urban migrants. The results indicate a significant association between objective SES and subjective well-being and a partial mediating effect of subjective SES. Furthermore, subjective social mobility, which is one’s expectation about the possibility to move upward in the social hierarchy, was found to moderate both the direct path from objective SES to subjective well-being and the indirect path from subjective SES to subjective well-being. These findings suggest that Chinese rural-to-urban migrants gained in subjective well-being not only because of direct financial achievement but also because of their perceptions and beliefs about their relative social status.

The adverse impact of a low family socioeconomic status (SES) on rural-to-urban migrant children’s academic achievement has been widely demonstrated. However, knowledge regarding the mechanisms underlying this relationship is limited. The current study aimed to examine the potential mediating effects of educational expectations and the moderating effects of subjective SES on the relationship between family SES and academic achievement among Chinese rural-to-urban migrant adolescents. A sample of 321 rural-to-urban migrant adolescents (48.2% girls; mean age = 11.73 years, SD = 1.16 years) was recruited in China. The results indicated that migrant adolescents’ educational expectations mediated the relationship between family SES and academic achievement. In addition, the link between family SES and educational expectations was weak among adolescents with higher levels of subjective SES. These findings suggest that subjective SES serves as a protective factor buffering the negative effects of a low family SES on migrant adolescents’ academic achievement through educational expectations.
