摘要：

针对需求同时受产品质量、平台服务水平、团长服务水平以及平台与团长竞合关系影响的供应链协调问题, 分别构建集中决策、分散决策、协调契约的供应链决策模型, 设计传统成本共担契约、两部定价契约与“收益共享+佣金”混合契约, 分析了产品质量以及双边服务水平对竞合供应链协调前后成员利润和最优决策的影响。结果表明: 两部定价契约和“收益共享+佣金”混合契约相较于传统成本分担契约, 能够有效协调竞合供应链; 消费者对产品质量、双边服务的偏好增加, 有助于扩大产品的市场需求, 提高竞合供应链协调后整体与各成员的利润。

关键词: 社区团购, 竞合供应链, 产品质量, 平台服务水平, 团长服务水平

Abstract:

Aiming at the supply chain coordination issues that the demand is affected by product quality, platform service level, service of team leaders, and the competition and cooperation relationship between the platform and team leaders, the supply chain decision-making models of centralized decision-making, decentralized decision-making, and coordination contracts are respectively built. The traditional cost sharing contract, two-part pricing contract, and "revenue sharing+commission" hybrid contract are designed. This paper explored the impact of product quality and bilateral service levels on the profits and optimal decisions of members before and after coordination in a competitive and cooperative supply chain. The results show that the two-part pricing contract and the "revenue sharing+commission" hybrid contract can effectively coordinate competing supply chains compared to traditional cost sharing contracts; the increase of consumers' preference for product quality and bilateral services contributes to expand the market demand for products, and improves the profits of the overall members of the competitive and cooperative supply chain under coordination.

Key words: community group purchase, competitive and cooperative supply chain, product quality, platform service level, service level of team leaders
