In recent years, the model of Supply Chain Finance has become an effective way to solve the financing difficulty of small-and-medium enterprises (SMEs). Supply chain finance has large market potential, which is becoming a new area of competition among banks. While research on supply chain contracts in recent years is an issue, so it is practically significant that if research on supply chain contracts and Supply Chain Finance are brought together, as well as, to explore the collaborative optimization of fund and operation in the supply chain. This paper establishes financing and operation model on the basis of revenue sharing contract. Based on the numerical example, it comes to a conclusion that revenue sharing contract can make SCF coordinate when the fund constraints exist.
