【Abstract】Based on the data of 2014 Migrant Dynamics Monitoring Survey in China, this paper uses Probit model and Heckprobit model to examine the impact of medical insurance coverage on the catastrophic health expenditure of migrants. The results show that people covered by basic medical insurance have a lower incidence of catastrophic health expenditure than those not covered. People with urban medical insurance have a lower incidence of catastrophic health expenditure than those with new rural cooperative medical insurance. In addition, the higher the reimbursement ratio is, the less likely catastrophic health expenditure happens. Therefore, this paper proposes that, in addition to ensure the universe participation in medical insurance program among migrant population, we should provide more urban medical insurance to those with more flexible employment to enhance the security level and to efficiently reduce the rate of catastrophic health expenditure. Meanwhile, we should further improve the medical insurance’s transferring policy, enabling migrants to reap the benefits brought by medical insurance.
