讲座摘要：

We consider an agricultural supply chain consisting of a capital-constrained smallholder farmer and an intermediary platform. The smallholder farmer sells agricultural products through the intermediary platform but lacks financial resources for sustainable production. In addition to the traditional bank financing (provided by a bank), the creditworthy intermediary platform may also directly provide loans to the farmer (known as direct financing) or serve as a guarantor if the farmer has insufficient creditworthiness to obtain bank loans (known as guarantor financing). We first consider the case where the unit commission fee charged by the platform is endogenized and find that the farmer produces the most under direct financing and the least under bank financing. Interestingly, under both guarantor financing and direct financing, the smallholder farmer's production level can be even higher than that in a centralized system. Moreover, the decentralized supply chain can be coordinated under direct financing when the farmer's production cost is relatively low. We show that the intermediary platform prefers financing the farmer directly when the farmer's production cost is low and would encourage the farmer to raise funds from the banking market when such cost is high. However, when the production cost is moderate, it is indifferent between direct financing and guarantor financing. The farmer always prefers bank financing while the preference of the whole supply chain is structurally similar to that of the intermediary platform. When the intermediary platform is also financially constrained, guarantor financing can be preferred by both the intermediary platform and the supply chain. We then consider another case where the unit commission fee is exogenously given. We show that now the farmer prefers either guarantor financing or direct financing. The preference of the whole supply chain hinges upon the magnitude of both production cost and the unit commission fee. Guarantor financing can be preferred by the intermediary platform only if it cares about the sustainability of the whole agricultural supply chain.
