ABSTRACT
OBJECTIVE：To provid e reference for the optimization and improvement of centralized volume-based procurement policy of drugs in China. METHODS ：Six provinces ，i.e. Hebei ，Jiangsu，Hainan，Henan，Jiangxi and Yunnan ，were randomly selected nationwide by random sampling to summarize and analyze the information of drug network withdrawal from Jan. 1st，2018 to Nov. 30th，2020. RESULTS & CONCLUSIONS ：Jiangsu province had the largest number of withdrawn products from the network，being 6 331；Yunnan province had the smallest ，being 101. Product price was the leading factor for drug network withdrawal，accounting for 89.12％；the second factor was product quality ，accounting for 7.06％；the third factor was the product supply，accounting for 2.91％. At present ，there were many problems in drug network withdrawal in China ，such as inconsistent withdrawal regulations in different regions ，unclear subjects of withdrawal behavior ，difficulty in sharing information of purchasing platforms in different regions ，unreasonable bidding rules of online drugs ，etc. Some suggestions are put forward to promote standardization of drug network withdrawal ，promote information sharing among provincial platforms ，actively develop drug price monitoring，support enterprises to make reasonable pricing based on cost ，strengthen departmental linkage and guarantee of drug supply so as to improve centralized volume-based procurement policy of drugs.
