Objective: The paper attempts to explore whether the implementation of a parity health insurance system can reduce the health disparity between different income groups. Methods: Based on the CFPS data from 2016 to 2020 , various statistical yearbooks and relevant policy documents, this paper examines the impact of equalized basic health insurance policies on health inequality among different income groups using DDD model through the lens of the provincial coordination of urban employees’ basic health insurance. Results: (1) Compared with the middle and high income groups, the probability of chronic diseases in the low income group decreased significantly by about 6.80% after the coordination policy, indicating that the provincial coordination policy alleviated the health inequality; (2) The low income group mainly improved their health status by increasing the probability of medical treatment and the frequency of physical exercise and the effect of medical expenditure on improving the health status of low income groups is not significant; (3) After the provincial coordination, retired employees have a higher evaluation of their own health status. Conclusion: It is recommended to gradually promote the provincial coordination of medical insurance and the equalization of healthcare services, strengthen the guarantee of disadvantaged groups, improve the national health literacy, and promote social equity.
