Logistics sharing mode selection and pricing strategies in platform supply chain

The development of e-commerce brings development opportunities to the manufacturer, prompting them to use logistics services to improve market competitiveness in a competitive marketplace. The high-quality service of self-operated logistics undoubtedly brings great benefits to the manufacturer, so it is crucial that e-commerce platforms are willing to share their self-operated logistics systems under what circumstances. In this paper, a platform supply chain system consisting of a manufacturer, an e-commerce platform, and a third-party logistic provider is considered, and a Stackelberg game model is developed to study the optimal decision of supply chain members under the logistics non-sharing mode and the logistics sharing mode. The study finds that the increase in the research logistics service fee leads to a corresponding increase in the logistics service level, as well as an increase in the sales price and a decrease in the wholesale price. And an increase in the commission rate only leads to an increase in the self-operated logistics service level. But the impact of these two parameters on the profitability of the members of the platform supply chain is non-monotonically variable. When the logistics service sensitivity coefficient is small, and when the logistics service sensitivity coefficient is large and the commission rate is high, the platform and the manufacturer achieve a win-win situation under the logistics sharing mode.
