Housing is the important place for migrant workers to enter and integrate into the city and public housing is one of the essential measures to improve migrant workers’ living condition. We systematically investigate the impact of public housing on the new generation of migrant workers’ willingness to stay in cities using the China Migrants Dynamic Survey in 2012. The results show that:(1)The proportion of the new generation of migrant workers living in public housing is less than 2%,indicating that the construction of the public housing for migrant workers still has a long way to go. (2)Compared with renting,public housing has a significant positive impact on the new generation’s willingness to stay in the city,and the conclusion remains consistent after adding other explanatory variables. Besides,we employ the propensity score matching to construct a counter-factual framework to correct the potential selective bias in the model that might confound our causal estimates. (3)There are differences in the impact of public housing on the willingness of new generation migrant workers to stay in cities. Compared with post-90s,the impact of public housing on post-80s is more obvious. Therefore,in order to give full play to the role of public housing in the migrant workers’ citizenization,we propose to highlight the diversity and differentiation in the construction of public housing,give priority to migrant workers working or living over five years in cities and post-80s migrant workers,and reform the housing system for the advantage of the new generation of migrant workers.
