Financing Mechanism Design of Small, Medium and Micro Manufacturing Enterprises with Capital Constraints in Different Life Cycle Stages

 In order to solve the problem that manufacturers have sufficient funds when producing traditional products and lack of funds when producing green products, this paper considers three financing strategies: no financing, bank loan financing and internal financing, and constructs centralized decision-making and manufacturer-led Stackelberg game model. It is found that the wholesale price, production input, green input level and supply chain profit of the three financing methods are not optimal under the manufacturer-led decision-making. On this basis, aiming at the overall profit under centralized decision-making, this paper designs the combined contract of "revenue sharing contract + two-part cost + green cost sharing" to coordinate the supply chain, and puts forward the scope of optimal coordination of the combined contract under three financing models.
