Based on the survey of the National Dynamic Monitoring of the Floating Population of China in 2014, this paper applies ordered logit model to present statistical evidence showing how residential difference can lead to variations in the probabilities of settlement of the floating population. The empirical results show that the residential difference is positively related to the settlement intensions of migrant workers. Specifically, the probability of settlement for the people who live in commercial housing is the highest, followed by those living in government subsidized housing and rental private housing, while those living in work unit housing is the lowest. Therefore, in order to promote the process of urbanization, we should respect migrants’ settlement intensions and achieve the goal of their permanent settlement by improving the multi-level residential pattern and establishing a multiple security housing supply systems.
