Research Of The Financing Model And Risk Measurement By Copula Function Based On E-Commerce Supply Chain Finance

With the rapid development of Internet technology and electricity merchants,the supply chain production mode is flourishing and the supply chain finance based on e-commerce platform is coming.This new supply chain financing model provides systematic financing support for the entire industry chain,mainly by controlling the flow of goods,logistics,capital flows and information flows in goods and services transactions,so it can solve the problem of supply chain funds tension and high cost of financing.This paper analyzes the supply chain financial model and problem of electricity supply business credit decision,starting from the background and actual business of supply chain finance in e-commerce platform.We have sorted out the relevant literature in recent years,and combined with the current real business,explained the related concepts,the main and characteristics about supply chain finance.From the point of view of electricity business,we set up the supply chain financial credit decision model based on CVaR risk model,that the electric business enterprises as the core business,both financing upstream and downstream enterprises,and are familiar with the overall supply chain business compared to traditional financial institutions.In risk,the e-commerce can reduce the upstream and downstream financing rates to ensure the normal supply and sale of products.It not only considers the benefits of its own loans,but also uses the repurchase strategy to maximize the expected profit of the supplier,and to share the risk of retailers,and thus pay more attention to the integration of supply chain revenue.At present,domestic research mainly focuses on the theoretical research of supply chain financing and types of risks,and uses more qualitative analysis methods.However,there are few concerns about the risk measurement problems in enterprise supply chain financing.Based on the case of Jingdong supply chain finance,this paper uses the Copula function to establish the Copula-CVaR quantification model from the perspective of financing enterprises,so as to visually evaluate the financing risk of enterprises.The model not only measures the default risk of a single enterprise,but also uses the relational principle to measure the risk value of the enterprise,thus obtaining the overall risk value of the supply chain.By measuring the potential portfolio of potential firms in the value of risk,we provide a reference value and reasonable behavioral constraints for the financing of the financial sector financial decision.
