农业供应链外部融资的发展条件――基于信息经济学的数理分析
Development conditions of EFASC: A mathematical analysis based on information economics

摘 要： 通过构建农业信贷市场均衡模型，从理论层面考察了农业供应链外部融资的发展条件，并结合实际，探讨了我国农业供应链外部融资发展面临的现实挑战及改进路径。研究发现：核心企业的信息优势可以降低甄别农业经营主体风险类型所需的信息租金；农业经营主体与核心企业的利益绑定，能有效降低核心企业参与农业供应链外部融资的信息门槛；社会收益和违约风险在银行和企业间的分配结构，同样是影响农业供应链外部融资发展的重要因素。
Abstract: By constructing the model of rural credit market equilibrium, the present essay undertakes both a theoretical investigation into the development conditions of External Finance in Agricultural Supply Chain (EFASC), and a practical exploration into challenges and improvement of EFASC development in China. The study finds that information advantage of a core company can decrease information rent of indentifying AMEs’ risk type. The increase of common interest between AMEs and the core company can lower the information threshold for the core company to participate in EFASC. The benefit and risk distribution between the core company and bank also have a significant impact on EFASC’s development
