Medicines are an important carrier for hospitals to provide diagnosis and treatment services. With the vigorous development of Internet hospitals，the matching drug supply model has gradually changed from the “prescription hospital circulation-offline medicine” model to “prescription online circulation-drug delivery”. In order to understand the development status of this model，the research focuses on the policy background，scope of supply，supply process，mode and other aspects of drug supply in Internet hospitals. It also analyzes and explores the main issues involved in the current drug supply of Internet hospitals，including the low actual circulation rate of prescriptions，and the possibility of induced drug purchase and benefit transfer in enterprise-led platform-type Internet hospitals. It is recommended to improve the drug supply and guarantee capabilities of Internet hospitals through measures such as improving the relevant legal system and standardizing industry standards.
