Research On Emission Reduction Decision-making And Coordination Of Closed-loop Supply Chain Under Carbon Trading Mechanism

Since the beginning of the 21 st century,global carbon emissions have grown rapidly,and climate change brought about by greenhouse gases is threatening ecosystem and human security.As the largest developing country,China attaches great importance to global climate change and gradually implements a series of carbon emission plans such as carbon peaking and carbon neutrality.In the context of low-carbon development,enterprises’ carbon emissions are constrained,and remanufacturing is adopted by enterprises as a production method for energy conservation and emission reduction,and the launch of carbon trading markets affects enterprises’ production,pricing and emission reduction decisions.Therefore,this paper explores the decision-making and coordination of enterprises’ emission reduction under the carbon trading mechanism.This paper takes the closed-loop supply chain composed of a single manufacturer,a single retailer and consumers as the core,with the manufacturer as the leader,and uses game theory,supply chain coordination and other theories to explore the introduction of carbon emission reduction technology and the introduction of carbon emission reduction technology Regarding the issue of emission reduction decision-making and coordination under the two circumstances,this paper first summarizes the research background and significance of emission reduction decision-making and coordination in the closed-loop supply chain under the carbon trading mechanism.From the two perspectives of decentralized and decentralized decision-making,four models of manufacturers introducing and not introducing carbon emission reduction technologies were constructed,and the optimal emission reduction model was obtained by comparing and analyzing centralization and decision-making,introducing carbon emission reduction technologies and not introducing carbon emission reduction technologies Strategy.Subsequently,the closed-loop supply chain that introduces carbon emission reduction technology is further coordinated by using the emission reduction cost-sharing-benefit-sharing contract,which reduces the cost pressure of manufacturers and promotes the coordination of the supply chain system.The research found that whether the carbon emission reduction technology is introduced or not,the decisions under the centralized decision-making are better than those under the decentralized decision-making,and the decentralized decision-making weakens the overall revenue of the supply chain;when the model constraints are satisfied Under these conditions,the unit new product carbon emissions and retail price are increasing functions of carbon emission reduction costs,and the overall profit of the supply chain is a decreasing function of carbon emission reduction cost coefficients;wholesale price and retail price are increasing functions of carbon transaction prices,and the overall supply chain Profit is a decreasing function of the carbon transaction price.Under decentralized decision-making,the carbon emissions per unit of new products and the manufacturer’s profit show a trend of decreasing first and then rising with the increase of carbon transaction price;The range of values realizes the coordination of the supply chain.Enterprises should implement carbon emission reduction technology,and adjust the input cost of carbon emission reduction technology by comprehensively considering the cost coefficient of carbon emission reduction and carbon trading price;the government should vigorously promote the development of green and circular economy,forcing enterprises to reduce emissions,At the same time,it will improve consumers’ awareness of environmental protection,increase the recognition of remanufactured products,promote the promotion of recycling activities,promote the development of the remanufacturing industry,formulate appropriate carbon trading policies to encourage enterprises to reduce emissions,and promote high-quality social and economic development.
