Abstract: By making use of 2014 dynamic monitoring data of migrant population and applying the treatment effect model, this paper verifies the impact of medical risks and medical insurance on the consumption of migrant population. The total consumption level of migrant population is lower than that of the permanent residents in cities and towns, and is higher than that of the rural population. But the entertainment expenses of migrant population are less than that of the residents in urban and rural population. In addition, the hospitalized risks and medical expenses of migrant population are both less than that of the resident population. The results show that the higher the occurrence rate of hospitalization, the lower the consumption level will be. As for those groups with lower income, the consumption level of them with urban medical insurance is higher than those who don’t have. As for those who have middle-low income, the consumption level of those who have rural medical insurance is lower than those who don’t have. Therefore, we suggest that in order to promote the consumption of the migrant population, we should firstly reduce the medical risks of the migrant population; secondly we should encourage migrant people, especially those with middle-low income, to take part in urban medical insurance; and thirdly we should also raise the income of the migrant population.

Key words: consumption of migrant population; medical risks; medical insurance
