制造商资金约束下的低碳服务供应链融资契约

Low-carbon Service Supply Chain Financing Contract under Manufacturer Capital Constraint

针对制造商减排资金不足问题,以制造商、减排服务商和零售商组成的低碳服务供应链为研究对象,通过设计基于减排服务商垫资的融资契约,得到了融资契约下供应链成员的最优决策以及最优利润,进一步分析了制造商自有资金对整个低碳服务供应链成员决策及利润的影响。研究表明,最优产品减排量、最优融资利率、最优批发价格和最优零售价格均与制造商自有资金呈正相关。但低碳服务供应链成员的最优利润与制造商自有资金的关系并不确定,随着制造商自有资金的增加,制造商和零售商的最优利润均先减少后增加;而减排服务商的利润随制造商自有资金的变化则受到消费者低碳偏好和单位减排量费用的影响。

In this paper,with a low-carbon service supply chain composing of a manufacturer,an emissions-cutting service provider and a retailer as the research object,in view of the lack of emissions-cutting funds on the part of the manufacturer,we designed a financing contract based on fund advance by the service provider and arrived at the optimal decision-making and optimal profit of the members of the supply chain under the financing contract.Next we further analyzed the impact of equity fund of the manufacturer on the decision-making and profit of the supply chain members,which found that optimal product emission reduction,optimal financing interest rate,optimal wholesale price and optimal retail price were all positively correlated with the equity fund of the manufacturer;however,the relationship between optimal profit of the supply chain members and the equity fund of the manufacturer was not certain;with the increase of the manufacturer's equity fund,the optimal profit of both the manufacturer and the retailer would decrease before turning to increase;and the change in the profit of the emissions reduction service provider with the equity fund of the manufacturer were affected by the low-carbon preferences of the consumer and the unit cost of emissions reduction.
