Abstract: Based on the theory and method of " job embeddedness”, taking " city embeddedness” as the core conception, the rural-urban migrant workers’ urban embedded scale is constructed from the perspective of social psychology through literature review, in-depth interview, and structured questionnaire. After exploratory factor analysis, it is determined that the scale contains 29 project indicators and precipitates two second-order factors (the pull of city embeddedness and the push of city embeddedness) and five first-order factors (sense of welfare, sense of linkage, sense of support, sense of deprivation and sense of gap). Using the scale to assess the differences in city embeddedness between the citizen groups and the rural-urban migrant workers, the results show that the difference between the mean and the detection rate of the two groups is significant in the sense of deprivation, sense of linkage, sense of support, and sense of gap. The reliability and validity test results show that the scale has good psychometric characteristics. It can effectively measure the urbanization status of the rural-urban migrant workers from the perspective of psychological integration.
