基于碳税的供应链合作减排补贴策略研究

A Research of Subsidies for Cooperative Emission Reduction in Supply Chain based on Carbon Tax

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。为了研究此类合作减排的补贴策略问题，本文在基于政府向终端产品收取碳税的政策下，构建了三阶段政企博弈模型，对无政府补贴、投入补贴、减排量补贴三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、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。

Abstract:

To achieve low carbon sustainable development, the supply chain enterprises cooperate in R Dto fully take advantage of respective capacity. How to make subsidy policy on supply chain enterprises who 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 three situations are analyzed and compared: no subsidy, subsidy for input of R D, subsidy for amount of emission. The conclusion is:fiestly, whether theSgovernmentSprovides subsidy or not,SenterprisesSwillScooperate inSemission abatementSunerSthe carbonStax; seccondly, the both subsidy policies can promote the emission reduction, corporate profits and social we-lfare. But The effect of subsidy on amount of emission is more significant than that of the input subsidy.
