Abstract: This paper considers a supply chain system consisting of one manufacturer and two competitive suppliers. One of the suppliers has capital constraint, so that its own capital is insufficient to complete production tasks. As a result, it is necessary for the capital-constrained supplier to get financing support to complete the production. With regard to the internal and the external financing methods, this paper separately constructs the revenue models of supply chain members, analyzes their optimal decisions under both methods, and compares the two financing modes through numerical experiments. The results show that when the level of production uncertainty is low, the profits of the supply chain members are higher, and the production enthusiasm of the capital-constrained supplier is higher under the internal financing method than those under the external financing method. The results also show that the inconsistent preferences for financing methods between manufacturer and supplier lead to decreasing profit for the manufacturer. While fortunately, it is possible for the manufacturer to induce the supplier to choose the preferred financing method through providing subsidies, which will increase its profit.
