Abstract: Value-added services of industrial internet platforms can improve manufacturers’ mass customization and product quality, thus increasing demand, on the one hand, and reduce production and manufacturing costs by improving efficiency, on the other hand. In this paper, a three-level supply chain game model consisting of an industrial Internet platform, a manufacturer and a retailer is constructed, and the optimal decision is solved based on usage-based and subscription-based charging models. The impact of value-added service sensitivity coefficients and cost savings coefficients on supply chain members’ decisions and profits under different pricing models is analyzed, and the optimal decisions under the two pricing models are compared. It is found that (1) the quality of value-added services, platform, manufacturer and retailer profits increase with the increase of consumer value-added service sensitivity coefficient cost savings coefficient under both usage-based and subscription-based models. When the value-added service sensitivity coefficient is greater than a certain threshold, both the wholesale and retail prices of products increase with the increase of the value-added service sensitivity coefficient. When the cost savings factor is less than a certain threshold, both the wholesale and retail prices increase with the increase of the cost savings factor.
