绿色信贷支持下供应链低碳技术采纳决策研究

Decision-making of Low-carbon Technology Adoption in Supply Chain Supported by Green Credit

在消费者具有低碳偏好和碳交易的环境下,考虑通过绿色信贷与供应链成员分担解决制造商低碳技术采纳中的融资难题,建立企业基本模型和供应链Stackelberg博弈模型并进行对比分析。结果发现:供应链受低碳环境驱使倾向于采纳低碳技术,绿色信贷支持有助于加强采纳决策的倾向性;绿色信贷利率折扣越大、融资比例越多,越能够激励供应链采纳更高水平的低碳技术;通过商讨合理的供应链内部成本分担比例,可实现投资收益和低碳技术采纳水平的双重优化。

Under the circumstance of consumers with a low-carbon preference and carbon trade, this paper uses green credit and cost sharing with the supply chain members to solve financing problems of low-carbon technology adoption faced by manufacturer, and establishes the basic enterprise model and supply chain Stackelberg game model for comparative analysis.The results show that the supply chain is driven by interests in a low-carbon environment and tends to adopt low-carbon technologies. Green credit can help to strengthen the tendency of adoption decisions. The greater the discount on green credit interest rates and the greater the proportion of financing, the better it can incentivize the supply chain to adopt a higher level of low-carbon technology. A reasonable cost-sharing ratio got by negotiating within the supply chain can optimize both revenue and low-carbon technology adoption.
