Generalized linear mixed model was used to estimate the interaction effect between China’s Rural Hospital Delivery Subsidy policy and site on hospital delivery rate. In model 1, policy, site and policy*site are treated as fixed effects and village as random effect. The model 2 is the model 1 plus women’s age, health score, prenatal visits during pregnancy, chronic disease, health insurance, annual household income, parity, education and work.
