Research on Health Insurance Policy for Migrants Based on Double Difference Algorithm

This study was carried out to delve into the impact of the migrants's health insurance policy using the double-difference algorithm. The double-difference method was used to exclude unnecessary data. By comparing the health insurance participation of the migrants with that of the non-migrants, the fixed effects of time and region were studied to accurately estimate the impact of the policy. Changes in health insurance participation rates, health care expenditures, and health care utilization were also discussed.
