Rental housing is the main way to meet the housing needs of migrant workers in the new urbanization process. In Shanghai, migrant workers solve the housing problem through market rental housing and affordable rental housing. These two types of rental housing are totally different in principal investors, rental housing management, tenants, rent pricing, location and government support. The statistical analysis based on the dual logistic regression model shows that rental housing has a significant impact on migrant workers’ willingness to stay in the city. Specifically, many factors such as educational level, the time in the city, the stability of housing, the rental housing conditions and the satisfaction perceived on the commuting time significantly influence their settlement willingness. This suggests that in order to promote migrant workers’ willingness to settle in urban areas, the government shall increase investment on the education and training of migrant workers, give more policy support to the migrant workers who live long time in the city, ensure the stability of the rental housing lease, make rental housing facilities and service standards, improve the ability of rational planning on the affordable rental housing location and improve the management level of affordable rental housing.
