Abstract: In the closed-loop supply chain,considering the participation of a big data service provider and assistance in recycling and marketing,the reputation of the manufacturer was introduced to study the impact of different big data services on the closed-loop supply chain.The Ito process was used to characterize the recovery rate perturbed by multiple factors,and the influence of parameters such as the sharing ratio and payment level of the big data service cost on the members of the closed-loop supply chain was analyzed.Research showed that when the industry reached saturation,the assistance of a big data service provider would not significantly improve the environment and economic benefits;if the assistance of big data service providers in marketing could effectively stimulate the market,the recovery rate,recovery effort level and profit improvement might be higher than the assistance recovery situation;the manufacturer was more likely to be disturbed by uncertain factors,and the level of recycling effort and profits fluctuate more,but fluctuations could increase the level of recycling effort and profit to a certain extent.The retailer's retail prices and profits tended to stabilize for a shorter period of time,and they could perceive market changes and respond faster;when the payment level of big data service fees was higher than a certain threshold,corporate profits would be reduced.
