ABSTRACT
With the continuous expansion of the domestic population flow,the medical and health services is-sues of migrant population are becoming more and more serious. Based on the three aspects of the demand,supply, and utilization of health services,this article explores and analyzes the utilization of health services for migrant popu-lation in Beijing in 2015 on the basis of behavioral models. The results showed that the prevalence of chronic diseases and the frequency of disease in migrant population are relatively low. The migrant population has low efficiency and overall evaluation of public health services. From the point of view of convenience and diversity of services,the sup-ply of public health services needs to be further improved. In terms of the active utilization of medical and health services,the proportion of respondents who did not participate in any medical insurance still have a large proportion, while the proportion of regular physical examination was lower. In terms of passive utilization,both outpatient and in-patients service use are low. Family income and medical insurance have influenced patients'choice of medical institu-tions to some extent. The health promotion strategy is proposed from the perspective of supply side and utilization.
