The report was chaired by Prof. Li Jinlin, and more than 30 faculty members and students attended the report meeting.

　　Associate Professor Shi Ju combined her recent experience in the reform of the medical expenses forecasting and payment system for residents in China, the impact of new rural cooperative medical care in China on the use of medical services, the impact of basic drug systems on the use of medical services, and the impact of U.S. medical reforms on residents’ behaviors. The research work introduced the research results and research trends of China's residents' medical cost forecasting and payment system, and proposed the theory of grading diagnosis and treatment based on the actual situation of tertiary diagnosis and treatment in China, combined with the application of RD, DID and other methods.
