Impacts of Power Structurer on Agricultural Supply Chain Under Partial Credit Guarantee
Partial credit guarantee(PCG)can help farmer obtain loans with lower interest rate from bank through core enterprise guarantee in the agricultural product supply chain,which can effectively alleviate the financial pressure faced in the production of agricultural product.This paper considers a three-level supply chain composed of agricultural material supplier,farmer,and agricultural product retailer,where farmer is short of funds and the yield is uncertain.Under different supply chain power structures,the problem of PCG de-cisions is studied.The study found that under the Nash structure,when supplier provides guarantee to farmer,farmer's enthusiasm for production is higher than that of retailer pro-viding guarantee;under Stackelberg structure,when supplier/retailer act as supply chain leader,their profit under PCG are higher.Finally,through numerical analysis,it is fur-ther verified that the Nash structure is better than the Stackelberg structure as under Nash structure,farmer is more motivated to produce and the overall profit of the supply chain is greater.What is more,under Nash structure,farmer,supplier and retailer all prefer supplier guarantee.
