摘　　要：针对产品需求受货架空间与零售价格共同影响的两级供应链,通过比较供应商主导、零售商主导和权力均等三种不同权力结构供应链均衡结果,分析了供应商与零售商共同承担货架空间成本对供应链定价、货架空间分配和利润的影响。研究结果表明:供应商与零售商共同承担货架空间成本会减少供应商主导供应链的整体利润,但会使零售商主导和权力均等供应链通过分配更多的货架空间增加产品销量,在一定范围内使得供应链整体利润得到提高。由于三种不同权力结构供应链均未达到整体最优,提出了基于货架成本共担的收入共享合同,并给出了供应商和零售商均能接受的分配方案。With the rapid development of e-commerce,how to improve the supply chain performance and maintain the competitive advantage is an urgent problem to be solved by the traditional physical distribution channels.Compared with e-commerce,shelf space is a scarce resource of the physical distribution channels which can display products for the consumers to learn and select.Since the shelf space has an important effect on product sales,the suppliers like to share the shelf space cost to get more shelf space.At present,the related research has not addressed how the performance of the supply chain under different power structures is affected when the supplier and retailer share the shelf space cost.The paper investigates a two-echelon supply chain consisting of a supplier and a retailer in which the demand facing the retailer is both price and shelf-space sensitive.In the first part,when the supplier and retailer share the shelf space cost,the decentralized supply chain models are built to investigate optimal decisions of the wholesale price,retail price,and shelf space allocation under different power structures,namely supplier Stackelberg,retailer Stackelberg,and vertical Nash.By comparing the equilibriums of the three models,this study found that when the shelf space cost is shared,the performances of the three supply chains are affected differently.In the supplier Stackelberg supply chain,the wholesale price and retail price are increased,and the shelf space is not monotonically increased as the supplier shares more shelf space costs.Also,the profits of the supplier,the retailer,and the total supply chain are all decreased.However,in the retailer Stackelberg and vertical Nash supply chain,the wholesale price and retail price are kept unchanged,the product sales are promoted by allocating more shelf space.The retailer gains more profit as the supplier shares more shelf space costs.The profits of the supplier and total supply chain are also increased when the cost shared by the supplier is less than a threshold.In the se
