Enhancing job security for low-income groups is essential to achieving opportunity equality and a crucial step in implementing human-centered modern urbanization to support the citizenship of migrants. Using data from the China Migrants Dynamic Survey conducted in 2015-2018, this research empirically investigates the effects of minimum wage on labor supply of migrants. It is found that there is a non-linear relationship between the labor supply of migrants and the minimum wage, and as the minimum wage rises, the working hours and the probability of overtime work of the migrants show a tendency to increase first and then decrease. In addition, the migrants of female, younger, migrated between urban and have higher education levels tend to reduce working hours at a lower minimum wage level. Further, by analyzing the impact of the minimum wage on the unemployment rate and labor structure of the migrant, there is no evidence that the minimum wage adjustment harmed the employment of low-income migrants. Based on this paper, we can comprehend how the minimum wage protects low-income migrants. Additionally, we can use this information to make decisions on promoting the integration of migrants into cities from an urban management standpoint.
