Research On Emission Reduction Strategy Of Low Carbon Supply Chain Based On Subsidy Policy

In the context of global warming,the "low carbon economy" that advocates low energy consumption and low pollution has become a global hotspot,and more and more enterprises have begun to implement low carbon emission reduction.Faced with the constraints of carbon tax and the pressure of R&D technology cost for emission reduction,the government will adopt subsidy policies to eliminate the pressure of carbon tax and cost,and encourage enterprises to actively participate in carbon emission reduction.So when the government faces the pressure of enterprises to reduce emissions and the different games between the main bodies of the supply chain,how to formulate a reasonable subsidy method on the basis of regulation to encourage enterprises to reduce emissions is a question worthy of study.Based on the supply chain low-carbon R&D and emission reduction methods,this paper studies the corresponding government subsidy policy effects.The main research contents are as follows:Based on the government’s policy of collecting carbon taxes and issuing subsidies,this paper constructs a low-carbon supply chain consisting of a manufacturer implementing carbon emission reduction and a retailer selling low-carbon products.Based on the three scenarios of chain-independent emission reduction and supply chain cost-sharing contract,taking the non-government subsidy as the benchmark model,this paper discusses the optimal supply chain members when the government adopts two subsidy methods: input subsidy to manufacturers and government emission reduction subsidy to manufacturers decision-making,and study the impact of different subsidies on carbon emission reductions,wholesale prices,retail prices and corporate profits.And finally,through model comparison and example analysis,it puts forward corresponding suggestions for the government to formulate emission reduction subsidy policies and corporate emission reduction decisions.The study found that under the three scenarios of supply chain cooperative emission reduction,supply chain independent emission reduction and supply chain cost sharing contract,both input subsidies for emission reduction and subsidies for emission reduction can have positive effects,but which subsidy method is better.It depends on the game situation of the supply chain.When the supply chain cooperates to reduce emissions,the effect of subsidies based on emission reductions is more effective than that of input subsidies based on emissions reduction;when the supply chain is independent to reduce emissions,for manufacturers wholesale prices,retail prices and corporate profits,the government will reduce Emission subsidy is more effective than input subsidy,but for the emission reduction effect,both government subsidy methods can increase the emission reduction of products.The choice of subsidy method depends on the size of the government subsidy rate;when When the supply chain adopts a cost-sharing contract,when the subsidy is based on emission reduction,the wholesale price and retail price are lower,and the profit of the manufacturer is higher;when the subsidy is invested in the emission reduction,the profit of the retailer is higher,and the emission reduction effect is proportional to the cost,subsidy method,subsidy rate are related.Finally,this paper provides a basis for supply chain enterprises to make emission reduction decisions,and provides a reference for the government to establish an effective subsidy method by the theoretical model and conclusions and gives the prospects for future researcher.
