摘要：

针对产品服务供应链中产品质量对产品及延保服务需求的多重影响问题，建立了制造商提供产品、强势零售商销售产品和提供延保服务的两周期利润模型，考虑强势零售商将前期采购的部分产品作为策略性库存用于后期销售的情形，分析了产品质量敏感系数、库存成本等对制造商和强势零售商价格决策和库存决策等的影响，分析比较了产品服务供应链集中式与分散式决策下的最优决策，通过强势零售商主导的"产品质量成本共担"契约来弥补制造商产品质量成本上升造成的相应利润损失以激励其提高产品质量。研究结果表明，强势零售商应主动分担制造商产品质量成本，进而促进产品质量的提高；强势零售商可以通过策略性库存降低制造商的产品批发价格，采取更加灵活的产品和延保服务价格策略。最后通过数值分析，验证了此种组合契约同时协调产品质量和产品服务供应链成员两周期定价决策的有效性。

Abstract:

Aiming at the multiple effects of product quality, a two-period Stackelberg dynamic game model is developed, which is based on the scenario that products are provided by a manufacturer and sold by a strong retailer who provides extended warranty. We analyze the influence of the quality sensitivities on the optimal decisions of product quality, price and inventories. We comparatively analyze the optimal decisions under centralized and decentralized supply chain. Furthermore, we design a "quality cost sharing" contract to remedy the loss of profit which is caused by the improvement of quality and motivate the manufacturer. The conclusions show that the strong retailer could encourage the manufacturer to improve the quality of the products and take the initiative to share the quality cost. The retailer could influence the wholesale price decision by carrying strategic inventories across two periods, and then affect the retail price. The "quality cost sharing" contract could improve the marketing effect of vertical marketing system. Finally, a numerical simulation is used to verify the effectiveness of the coordination contract.

Key words: product quality, extended warranty, strategic inventories, joint pricing, coordination strategy
