Research On Subsidy Strategy Of Supply Chain Emission Reduction Based On Carbon Tax

In the context of a low-carbon economy,carbon tax is used by countries due to their strong regulatory and operability.But the implementation of the carbon tax will bring some problems: increases product prices in the short term,affects corporate profits,and has a negative impact on economic growth.The government often uses subsidy policies to eliminate the negative impact of carbon tax and encourage companies to actively participate in low-carbon emission reductions.It is a very worthwhile discussion that establish a more scientific emission reduction subsidy mechanism.The paper studies the corresponding policy effects that based on the supply chain vertical cooperation low-carbon R&D and recycling of the two commonly used methods of emission reduction.Therefore,the main research content is as follows:Research on the subsidy strategy for technology researching and emission reduction in supply chain.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: firstly,whether the government provides subsidy or not,enterprises will cooperate in emission abatement under the carbon tax;secondly,the 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 of the input subsidy.Research on the subsidy strategy for reducing emission reductions in supply chains.The paper proposes a recovery and emission reduction model that third party is responsible for recycling and manufacture for remanufacture.Then compare and analyze three situations: no subsidy,subsidy for recycler's unit recovery,or subsidy for manufacture's unit reduction.The conclusion is: Carbon tax can reduce corporate carbon emissions,but it also reduces product market demand.Government subsidies can increase the recycling of old products,emission reduction,corporate profits and government benefits.The two subsidy mechanisms have same effect on recovery of old products which means recycling price,recycling amount,and carbon emission reduction are equal.At the same time,the effect of the two subsidy mechanisms on corporate profits and government benefits is also the same.Manufacturers share recycling revenues and government subsidies with recyclers through recycling transfer Prices.The government subsidy is proportional to the basic recovery of old products and inversely proportional to the unit recovery cost and carbon tax.When the government subsidizes recyclers,the subsidy is proportional to unit carbon reduction of remanufactured products;when subsidizes manufactures,the subsidy intensity must be comprehensively considered in terms of carbon reductions per unit of remanufactured product and unit costs saved.Finally,the management significance is extracted from the research conclusions,which provides a basis for the emission reduction strategy of supply chain companies and a reference for the government to establish an effective subsidy mechanism.
