零售商资金约束下绿色供应链融资策略

Financing Strategies of Green Supply Chain under Retailer’Capital Constraints

以单个制造商和单个资金约束零售商组成的二级绿色供应链结构为研究对象,考虑构建银行贷款、部分支付、延迟支付3种融资模式的Stacklberg博弈模型,分析消费者绿色偏好等参数对绿色供应链下各成员利润的影响,讨论各情形下供应链成员如何作出最优融资策略选择。研究表明:延迟支付融资模式下的最优产品绿色水平最高,银行贷款融资模式下的最优产品绿色水平最低;消费者绿色偏好与绿色供应链上的制造商、零售商的期望利润均成正相关,同时还与整条供应链的总期望利润正相关;当消费者绿色偏好小于一定的阈值时,零售商偏向于选择部分支付融资模式,而大于一定的阈值时,零售商倾向于延迟支付融资模式;制造商总是在延迟支付融资模式下期望利润最高。

The research object is a green supply chain composed of one manufacturer and one retailer with financial constraints.The Stacklberg game model is constructed under three payment methods:bank loan,partial payment and delayed payment.The influence of consumers’green preference,other parameters and the profit of the supply chain and selection strategy of financing mode are studied.The results show that the green level of products under the delayed payment financing mode is the highest,and the product green level is the lowest under the bank loan financing model.Consumers’green preferences are positively correlated with the expected profits of manufacturers and retailers in the green supply chain,as well as the overall expected profits of the entire supply chain.When consumers’green preference is less than a certain threshold,retailers prefer to choose a partial payment financing model.Above a certain threshold,retailers tend to delayed payment financing models.Manufacturers always expect the highest profits in the delayed payment financing model.
