Raising the income of migrant workers has always been the focus of social work for the past decade. Previous studies focused more on the education of migrant workers and the cultivation of their technical skills, but ignoring the cornerstone role of health. The outbreak of CO VID 19 epidemic has once again brought attention to the importance of health. The study analyzes the impact of health on the income return of migrant workers, focusing on the possible distinctive impacts of health on the income of migrant workers and that of urban workers. The results of the study indicate that health has di铤rent impacts on the income of the two types of employment. Compared with urban workers, migrant workers1 physical health is a more important human capital than their education received. The study suggests that in the process of normalization of epidemic prevention and control and the promotion of new urbanization, in order to increase the income return of migrant workers, relevant departments should not set limits on the promotion and cultivation of migrant workers* education, skills and other cognitive abilities any more. More attention should be paid to their health status, raising their income by improving their social security systems of medical and health care to support the improvement of health of migrant workers.
