All models included individual and household level covariates and district fixed effect. Standard errors adjusted for clustering at district level. All expenditure results were converted to comparable expenditure in 2018 with Beijing’s CPI. ***, **, and * indicated the significance at 1%, 5%, and 10% level, respectively
For results of every model, odds ratio was reported
PCHC Per capita annual household consumption
