摘　　要：网络零售业造节促销已成常态,优化网络零售平台(简称平台商)和销售商联合促销策略是一项值得深入研究的课题。本文基于收益共享契约,利用不同的博弈模型刻画入驻销售商和平台商之间三种不同的促销模式,包括由其中一方率先发起促销的模式和二者同时发起促销的模式,研究不同模式下销售商和平台商的最优促销策略。研究结论表明,在三种促销模式下,二者的最优促销策略均随着商品佣金费率的增长依次呈现三种不同的形式:从仅由销售商提供促销到联合促销再到仅由平台商提供促销。当且仅当佣金费率和商品的日常售价高于一定阈值时,销售商和平台商才会有动机开展联合促销。研究还发现,销售商和平台商在各自率先发起的联合促销模式下具备先动优势。销售商(平台商)率先发起的联合促销将更有利于对佣金费率较低(高)的商品实施。当销售商和平台商同时独立发起促销时,供应链整体促销力度最大,供应链的整体利润也最高。In recent years,it’s prevalent for the online retail platform(referred to platform hereafter)to hold large-scale sales promotion events.There are three types of sales promotion among all the promotional activities online.The first one is the platform that leads to initiate the promotion.The second is the seller that leads to initiate the promotion.The third is that no one leads the promotion,i.e.,the seller and the platform make decisions on promotional strategies independently as well as simultaneously.In each type of promotion,three strategies may appear,including only the seller offering a rebate,only the platform offering a rebate,or both of them offering a joint rebate.In each deal on the platform,the sellers always need to pay the commissions to the platform operator,which is a fix proportion of retail transactions.The commission rate is a long-term decision made by the platform after repeated practice in the operation,and different platforms or different products on the same platform may have different commission rates.This paper focuses on the instant rebate,which means the rebate set by the seller,and the platform is directly reduced from the original price of the product in each deal.This paper utilizes the revenue sharing contract to imitate the benefits relationship between the seller and the platform,where the only income of the platform is the commission provided by the seller.Nash game and Stackelberg games are used to model three different sales promotion types,and several specific case analyses are used to assist the verification.This paper addresses the following research problems:(1)What are the optimal promotion strategies for the seller and the platform?The unilateral promotion or the bilateral promotion(2)How do the parameters influence the optimal promotion strategies of the seller and the platform?(3)How do the different sales promotion types affect the promotion strength and the final profit in a joint rebate?(4)How to set optimal joint promotion strategies for different products,consid
