Objective: It evaluates the effects of DRG point payment scheme on the construction of county medical alliance, in order to provide evidence for the construction and improvement of medical alliance. Methods: A total of 4 county medical alliances and 6 municipal hospitals in Jinhua were selected to collect data on medical service volume, cost burden and income structure. The predicted values of each measurement index from 2018 to 2020 were obtained through the exponential smoothing method. The comparative analysis method of "projection-after implementation" was used to compare the changes of measurement indexes of hospitals at all levels before and after the implementation of the policy. Results: In 2019, the difference in the average number of outpatient and emergency patients in county-level hospitals was 13.75 %, and the difference in the average number of discharged patients in township hospitals was 23.08 %. In 2020, the differences of average hospitalization expenses in county-level hospitals and township hospitals were -8.59 %and -13.92 %, respectively. In 2020, the proportion difference of sanitary materials in county-level hospitals was -24.86 %. Conclusion: DRG point payment has increased the number of patients in the county, reduced hospitalization costs, and optimized the income structure of county-level hospitals. However, county-level patients' higher medical treatment is still prominent, the effect of cost control on municipal hospitals is not obvious, and the proportion of drugs and consumables is still large. It is recommended to continue to improve the DRG point payment scheme design and strengthen the guiding role of medical insurance payment scheme in the construction of county medical alliance and improve relevant supporting measures.
