基于消费者低碳偏好和内部融资的供应链碳减排决策

Supply Chain Decision-making of Carbon Emission Based on Consumer Low-carbon Preferences and Internal Financing

全球变暖问题日益严重,低碳产品的理念被越来越多的消费者接受,供应商需要进行碳减排改造以生产低碳产品。我国中小企业居多,而碳减排改造资金量需求较大,需要进行融资以获得碳减排改造资金。本文研究零售商为供应商提供内部碳减排融资,运用两阶段Stackelberg博弈在分散决策和集中决策两种情形下进行优化,以达到供应链最大化利润。研究表明,零售商主导的分散决策下消费者低碳偏好和内外部融资利率的升高均会导致分散决策供应链总利润升高,而单位碳减排量成本和外部投资利率的升高会导致分散决策总利润的降低,供应商主导的分散决策下仅批发价与内部融资利率有关,集中决策的利润仅与消费者低碳偏好和单位碳减排量成本有关,随消费者碳减排偏好增加而增大,随单位碳减排量成本增加而降低。本文针对分散决策和集中决策的结论可以用在不同类型的供应链中,以对实际的碳减排投资和融资进行参考。

Due to the serious problem of global warming,the‘low-carbon＇concept has been accepted by more consumers.The vast majority of small and medium-sized supply enterprises in China don＇t have enough money to operate carbon reduction modification to satisfy consumers＇ need.In this paper,the ‘max profit＇model containing internal financing from the retailer to the supplier is built and solved by two-stage Stackelberg game in decentralized and centralized decisions.The research indicates that the increase of low carbon consumer preferences,internal and external financing interest-rate lead to higher gross profit in retailer-leading decentralized supply chain,and the unit cost of carbon emissions and external investment interest-rate will have negative effects on retailer-leading decentralized supply chain＇s gross profit,while the internal interest-rate is only related to wholesale price in supplier-leading decentralized supply chain.The centralized supply chain gross profit rises as the low carbon consumer preference increases and the unit cost of carbon emissions decreases.Meanwhile,the centralized supply chain gross profit remains invariable as the internal and external financing interest and external investment interest change.The conclusion of decentralized and centralized decision can be used in different types of supply chains in the actual low-carbon investment and financing.
