Using data from the 2022 survey of households in public rental housing in Guangzhou,the impact of public education satisfaction on the fertility intentions of social housing renters is empirically tested by constructing a binary Logistic regression model. The instrumental variable approach is used to address the endogeneity issues between public education satisfaction and fertility, and disentangle the complex relationship between them. The results indicate that public education satisfaction significantly increases the fertility intentions of public housing renters. For low-educated public housing renters, the effect of public education satisfaction on their fertility intentions is stronger. It is suggested to further improve the planning, design, construction and allocation of public rental housing in order to effectively promotion and protection the willingness of public housing renters to have children, actively promote the equalization of public education services,reduce education costs， actively implement the "equal right to rent and purchase" and promotion of the right of tenant groups to enjoy equal rights in relation to public services.
