  Abstract: Based on the quasi-natural experiment Integrated Medical Insurance System(IMIS), this paper empirically verifies the effect of IMIS on the medical burden of middle-aged and elderly in China, by employing the data set of China Health and Retirement Longitudinal Study(CHARLS)and using the Heckman model under Difference-in-difference (DID) method. The results illustrate that, compared with those non-integrated areas, the policy of IMIS helps to reduce the burden of medical expenses of middle-aged and elderly patients, and the burden reduction effect of mode “single system, multi-standard” is better than the model of “single system, single-standard”. Based on the heterogeneity analysis among groups by age, it is showed that the “single system, multi-standard” model exerts significant positive to reducing the medical burden of the elderly over 65 years old, but no significant impact on the group of age in 45-55. Based on the heterogeneity analysis among groups by income, the results show that the IMIS policy is better for middle-income groups than low-income and high-income groups in reducing the medical burden, However, the integration model of “single system, single-standard” . In a word, the IMIS has achieved the expected effect that reducing the medical burden of rural middle-aged and elderly people and narrowing the gap between urban and rural medical security.
