摘　　要：在我国药品带量采购政策的背景下,采用博弈论的方法,构建了单个药品制造商和两个竞争性非对称药品零售商供应链结构模型,分析了竞争药品供应链的最优定价决策问题,探讨规模大小不同的非对称药品零售商的药品团购供应链系统协调机制。研究结果表明:虽然团购策略能够降低药品价格,但是供应链系统仍然存在效率损失。相关部门在药品团购中采用数量折扣与两部定价组合合同才能够实现供应链中各成员利润的帕累托改进,进而实现非对称零售商药品团购供应链的协调。Volume-based procurement refers to the group-buying model in which the required quantity of procurement is announced in the bidding,and the price and corresponding production capacity are considered in the bidding.The drug volume-based procurement can promote the reform of the drug sector,enhance the attractiveness of bidding,effectively solve the problem of falsely high drug prices in China,give full play to the advantage of"quantity for price",and play a positive role in improving patient welfare.At present,China's centralized use of procurement prices for similar drugs has been carried out and has achieved remarkable results.However,in addition to prices,the improvement of the overall efficiency of the pharmaceutical supply chain is also a key issue in management practice and research.Therefore,when considering downstream asymmetric retailers competing,what kind of effective mechanism should the government design to achieve the optimization of the pharmaceutical supply chain system?In view of this,it aims to design a more effective coordination mechanism to thoroughly solve the problem of profit distribution in asymmetric retailer group buying in this paper.From the perspective of horizontal competition in the supply chain,a competitive supply chain model between a single drug manufacturer and two asymmetrically competing drug retailers is constructed,in which drug manufacturers dominate the supply chain.Since drug retailers in asymmetric competition jointly purchase drugs in a group-buying model,drug manufacturers provide drugs to retailers with different purchase volumes at wholesale prices,that is,the drug purchase prices of competitive asymmetric drug retailers are the same.The Stackelberg game sequence of the three is as follows.Firstly,a single drug manufacturer sets a wholesale price based on the principle of profit maximization.Secondly,two competing asymmetric drug retailers with different market sizes set their own retail prices.The results of the research show that(1)The price sensitivity of drugs a
