Abstract: Since 2018, three rounds of China’s drug volume-based procurement （VBP）have been implemented, covering 112 kinds of drugs in total and saving about 53.9 billion health insurance expenditures every year. This paper focuses on the theoretical interpretations and empirical analyses of procurements. It is found that district choosing mechanism has a significant effect on bidding. The fusing mechanism is theoretically restricted by the cost factor, but it still exerts certain effects in practice. China’s VBP reform promotes the development of quality-and-cost-based competition in the drug market, and increases the concentration ratio of the industry. VBP is an indispensable route to deepen the health care reform, which contributes to the establishment of the health insurance payment criteria. The reform is extended from the nation level to provinces and cities, as well as from drugs to medical supplies. The core problem of centralized drug procurement is the information asymmetry of quality and cost of drugs, thus quality control such as consistency evaluation and pharmacovigilance still needs to be strengthened.
