ABSTRACT
Objective: To identify the impact of Urban Resident Basic Medical Insurance (URBMI) on medical service utilization. Methods: Based on data of China Health and Nutrition Survey, matching DID model was used to compare the changes in medical service utilization between residents participated in this system and those not participated in this system in 2009. Results:In initial stage of implementation, URBMI in a certain extent promoted medical service utilization of residents participated in the system, but the impact level was still low. The promoting effect on inpatient service utilization was significant, but very limited on outpatient service utilization. Conclusion:Promoting outpatient service utilization and increasing compensation are future priorities for improving URBMI to implement the system.
