The impact of ephemeral data sharing on e-commerce supply chain product quality and service strategies under channel power change

Based on the consideration of the ephemeral characteristics of data resources, this paper explore the impacts of data sharing on product quality and service strategies of manufacturers and retailers under different channel power structures by constructing a differential game model and numerical simulation analysis, and adopt a cost-sharing pact to coordinate the performance of e-commerce supply chain in order to realize high-quality data sharing and promote product quality optimization and service innovation. The results show that the overall data sharing level of the supply chain is higher when the retailer has the right to open online channels, which contributes to the improvement of product quality and service level, while the decay of data value has a negative impact, and the supply chain performance is improved under the cost-sharing contract, which helps to alleviate the double marginal effect of decentralized decision-making.
