This paper explores the mechanism of government housing policy reforms on the educational equity of children from disadvantaged groups, and constructs a logistic regression model based on China Family Tracking Survey (CFPS) data to empirically test the role of the intensity of housing system reforms on the availability of educational opportunities. Among the core explanatory variables, the dummy variable for low-intensity housing system reform areas has an opportunity ratio of 0.502 (p<0.01) in Model 1 and 0.604 (p<0.01) in Model 2. Controlling other conditions constant, children with higher family socio-economic status are more likely to enroll in public schools, and children from one-child families are twice as likely to enroll in public schools than non-one-child children. The PSM-DID robustness test further verifies the non-randomness of the policy effect, and the study provides theoretical basis for optimizing the housing policy and promoting the balanced allocation of educational resources.
