基于碳税的供应链合作减排补贴策略研究

摘要

在低碳可持续发展背景下,供应链企业会利用各自研发优势合作减排.为研究此类合作减排的补贴策略问题,在基于政府向终端产品收取碳税的政策下,构建三阶段政企博弈模型,对无政府补贴、投入补贴、减排量补贴3种情形进行比较分析.研究表明,在碳税政策下,无论政府是否给予补贴,企业都会进行合作减排;两种方式的补贴均可以提高减排量、企业利润和政府效益,但较投入补贴方式,政府按减排量补贴的效果更为显著.%To achieve low carbon sustainable development,the supply chain enterprises cooperate in R&D in order to fully take advantage of respective capacity.How can subsidy policy be made on supply chain enterpriseswho cooperate in emission abatement? To solve this problem,based on the emission tax on end products,the three-stage government-enterprise game model is established,in which threesituations are analyzed and compared including no subsidy,subsidy for input of R&D,subsidy foramount of emission.The conclusion is as follows:First,whether the government provides subsidy or not,enterprises will cooperate in emission abatement under the carbon tax;Second,both subsidy policies can promote the emission reduction,corporate profits and social welfare;But The effect of subsidy on amount of emission is more significant than that ofthe input subsidy.
