Supply chain financing provides a new financing model for SMEs, brings new revenue direction for financial institutions, and opens up a new way for SMEs financing through reducing the pressure of SMEs’ So it is necessary to study on supply chain financing model and credit evaluation system to provide new ideas and theoretical support for carrying out the supply chain financing business. Base on the basic coordination model of supply chain contract, this paper analyzes the strengths and key models of supply chain financing. Respectively, do research on the coordination of supply chain financing from different aspects, such as funds constrains, different market demand and credit evaluation and so on.First of all, through adding funds constrains in coordination of supply chain on buy-back contract, we work both on optimal policy of supplier, retailer and the financial institutions. Optimal order quantity based different funds of retailer. Per shortage of own funds, the probability of the retailer’s bankruptcy will be increased with the decreasing of the repurchase price, and gives the retailer bankruptcy condition and the relationship between finance interest rates and financing scale. Financial institutions should set reasonable financing rates and a certain degree of financial constraints.Secondly, for channel coordination model for the consignment contract, respectively, in the case of price elasticity of demand and linear demand analysis of supply chain performance of distributed systems, looking for ways to coordinate distributed systems, study two incentives:bonus system and Revenue Sharing with Side Payment (RSSP). Also study on whether these two incentives can coordinate the supply chain under certain conditions.Finally, based on the analysis of traditional credit evaluation system, use Two-dimensional Rating and Multilevel Grey system theory to set up supply chain financing credit evaluation system model, and this model can achieve both comprehensive evaluation for single firm and ranking for multiplayer. |
