Abstract: Taking the supply chain consisting of suppliers, 3PL companies,and retailers as the research background,this paper studies the retailer's optimal decision under the 3PL financing and bank financing model in view of the retailer's financial constraints and facing uncertain market demand.A Stackelberg game model is constructed to explore how different financing methods affect the decision-making of each participant in the supply chain,and explore the feasible range of freight rates for retailers to choose 3PL financing and the feasible range of bank interest rates for bank financing. The study finds that under normal circumstances, retailers will eventually choose 3PL financing. When bank interest rates are low or shipping costs are high, retailers ultimately choose bank financing; when 3PL companies and retailers cooperate through profit transfer contracts, and retailers choose 3PL financing, collaborating parties can achieve Pareto improvement.

Key words: supply chain capital constraints, 3PL financing, bank financing
