Using the micro data of the China Labor Force Dynamics Survey (CLDS), this study constructed an employment quality index of migrant workers by using the factor analysis method, it used the binary logistic model and the intermediary effect model to explore the urban-settlement intention of 1451 migrant workers in 29 cities in China, and it empirically analyzed the impact and internal mechanism of vocational-skills training on migrant workers’ willingness to settle in urban areas. The results show that (1) there is a significant positive relationship between the vocational-skills training and the migrant workers’ settlement intention. A further analysis showed that the empirical results remain robust after correcting endogeneity bias by using the instrumental variable model; and (2) participating in vocational-skills training can improve the employment quality of migrant workers, which would result in the increase of migrant workers’ willingness to settle in urban areas, and employment quality plays the significant intermediary role in this path. (3) The heterogeneity test results show that participating in vocational-skills training has a larger effect on the willingness to settle in urban areas of older-generation, female, and married migrant workers. Therefore, this paper makes the following suggestions: the government should do a good job of top-level design of vocational-skills training for migrant workers, increase investment in human capital of migrant workers, and improve the employment quality of migrant workers.

Using the micro data of the China Labor Dynamics Survey (CLDS), this paper uses factor analysis to construct urban integration indicators and uses the OLS model and intermediary effect model to study the urban integration of 1976 migrant workers in 29 cities in China. This paper empirically analyzes the impact of labor contracts on migrant workers’ urban integration and its mechanism. The study found that: (1) labor contract can significantly promote the urban integration of migrant workers. Further, this conclusion is still tenable after correcting endogenous bias with the 2SLS model and performing a series of robustness tests. (2) Signing labor contracts increases the participation rate of migrant workers in various insurances, enhances the social security level of migrant workers, alleviates the discrimination in the urban labor market, and thus enhances the urban integration of migrant workers. (3) The results of the heterogeneity tests show that the labor contract has a greater impact on the urban integration of the new generation, married and public sector of migrant workers compared with the old generation, unmarried and private sector of migrant workers. Therefore, this paper makes the following suggestions: the government should strengthen labor market supervision, encourage employers to sign long-term labor contracts with migrant workers, improve the social security system for migrant workers, and protect the legitimate rights and interests of migrant workers.
