In the context of sharing manufacturing, most equipment manufacturers provide services to consumers in two ways: selling equipments directly to consumers; providing manufacturing services through a sharing platform. The issues of consumers' decision-making and the equipment manufacturer's optimal pricing strategy are discussed in the selling model. In the servicization model, following the standard backward induction, the multi-stage dynamic game between players is solved, considering the for-profit sharing platform (maximizing self-revenues) and the not-for-profit sharing platform (maximizing social welfare). By comparing the equipment manufacturer's profits under the two models, the conditions for choosing each business model are investigated. Furthermore, the impacts of the popularizing rate of the sharing platform on supply chain members are examined, as well as environmental benefits of the two business models. For the not-for-profit sharing platform, a rebate mechanism is designed to coordinate the supply chain. Results show that the total social welfare reaches its maximum when the sharing platform returns all the benefits to consumers. This paper makes an analysis from the perspective of making full use of social resources and improving economic and environmental benefits, and provides a reference for all players' decision-making.
