Research on Coordination of the E-Commerce Platform Supply Chain Considering Tripartite AI Investments

This study examines a three-tier e-commerce platform supply chain consisting of a manufacturer, an e-commerce platform, and a logistics provider, where three members invest in artificial intelligence. Market demand is modeled as a function of retail price and the AI investment efforts of three members. To coordinate the supply chain, all possible coalition forms and the cost-sharing contract are investigated. Game models under different scenarios are established and solved. The results show that: (1) Compared with the centralized structure, each member’s AI investment effort will decrease under decentralized structures; (2) The cost-sharing contract is always effective for the AI investment efforts of the manufacturer and platform, but it is effective for the logistics provider’s AI investment effort under certain conditions; (3) The cost-sharing contract effectively coordinates the e-commerce platform supply chain compared to the revenue-sharing contract. Market demand and supply chain profit are larger under the cost-sharing contract than under the fully decentralized structure. This paper provides a theoretical basis for the design of AI investment strategies, product pricing, and coordination mechanisms for supply chain members of the e-commerce supply chain.
