  Abstract: Objective: DIP payment is an important component of Chinas medical insurance supply-side reform. This study aims to explore the synergistic effects of DIP and other medical insurance supply-side policies. Method: A city A that has piloted DIP reform was set as the treatment group, and a city B without reform was set as the control group. A total of 1,120 public medical institution samples from 2019 to 2022 were collected. The total medical expenses during hospitalization and some structural expenses were analyzed using the double difference method. Result: DIP had a significant inhibitory effect on the total medical expenses during hospitalization and the total expenses of checkups and examinations during hospitalization in city A (P<0.05), but had no impact on the total drug expenses and the total material expenses during hospitalization. Conclusion: DIP played a significant cost control role and effectively controlled the total medical expenses during hospitalization. The collaborative effects of price adjustment of medical services policy and national centralized drug/material procurement policy on cost control were insufficient. DIP synergized with other supply-side policies to promote rational medical cost structure. It is suggested that medical insurance departments should focus on the synergistic effects of medical insurance supply-side policies to jointly improve the efficiency of medical insurance fund utilization.

  Key words: DIP payment; Supply side reform; Price adjustment of medical services policy; national centralized drug/material procurement policy
