摘要
针对多家中小供应商存在低碳融资需求但缺乏外部融资渠道问题,基于融资担保理论,提出了核心企业统一授信担保融资模式。在确定中小供应商低碳融资需求的基础上,依据核心企业统一授信额度是否充足构建了两种配置模型,利用Karush-Kuhn-Tucker条件给出了核心企业的最优配置决策。在核心企业统一授信额度不足时对比了两种模型的配置结果,发现考虑低碳投资效率能够提高中小供应商总利润,但降低了核心企业及部分中小供应商的利润。进一步通过引入利润共享因子弥补了改进模型后部分企业的利润损失,实现了各方利润的帕累托改进。研究为存在低碳资金约束的中小供应商获得供应链融资提供了一种新思路。
Facing the environment of carbon market transactions and carbon quotas,there are many small and medium-sized suppliers with low-carbon financing needs in the same supply chain.However,they are prevented by the higher cost of external financing to develop low-carbon.At the same time,the stability of the entire supply chain is also affected.This paper attempts to solve the problem of internal financing in the supply chain when there are financing needs for multiple small and medium-sized suppliers in the same supply chain.For this purpose,under the theory of financing guarantee,the lowcarbon financing needs of many small and medium-sized suppliers in the supply chain are solved by using the unified credit guarantee financing of the core enterprise.On the basis of determining the low-carbon financing needs of small and medium-sized suppliers,two allocation models are constructed according to whether the unified credit line of core enterprises is sufficient,and the optimal allocation decision of core enterprises is given using Karush-Kuhn-Tucker conditions.When the core enterprise's unified credit line is insufficient,the results of the two models are compared,and it is found that considering the efficiency of low-carbon investment can increase the total profit of small and medium-sized suppliers,but reduce the profit of core enterprises and some small and medium-sized suppliers.In order to be able to subsidize core enterprises and small and medium-sized enterprises with reduced profits,the profit sharing factor is introduced to compensate for the profit loss of some enterprises after the improved model,and the Pareto improvement of the profits of all parties is realized.This mode may help small and medium-sized suppliers to mitigate the difficulties in financing for sustained development.Above all,the research may provide a new method for core enterprises to deploy low-carbon financing needs of multiple small and medium-sized suppliers.
