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
