Recycling And Carbon Emission Reduction Decisions Of Closed-Loop Supply Chain Under Different Corporate Social Responsibility Investment

In recent years,the rapid replacement of electrical products that has caused a lot of the used products,resulting a enormous pressure that reduces resource consumption and carbon emissions,and the reverse recovery channel has become a signifigant list of closed-loop supply chain corporate operation.At the same time,as low-carbon products are gradually known and recognized by consumers,realizing the cycle improvement of China,government plans some carbon policies(such as carbon tax,carbon control and trading policies,etc.)has greatly brought the advancement of emission reduction technology.To match environmental changes and increase the brand strength of products,manufacturers such as Gree,Midea and retailers such as SUNING,JD.com has also joined the ranks of reduces resource consumption and carbon emissions,not only vigorously promoting low-carbon household appliances in the sales link,but also initiating activities to consume new energy products for used appliances in the recycling link.Besides,enterprises make the invest in CSR to keep a perfect image and the higher profits;in fact,the leading manufacturers often get more channel profits and invest in CSR to assume the responsibility of the environment and other benefit members,achieving the cycle improvement of CLSC.At the same time,retailers usually invest CSR to stimulate consumption because they are closer to the consumer market.Based on the above background,under the carbon cap-and-trade mechanism,considering the impact of price and different emission reduction factors on market demand;it uses the Stackelberg game theory,market economy and Maple simulation software and other theoretical basis and methods.This paper explores the decision problem of CLSC considering the recovery of each member in different CSR investments.The main research work of this paper is as follows:In this paper,according to different CSR investment subjects,it is divided into two modes: CSR independent investment(manufacturer invest in CSR and retailer invest in CSR)and CSR joint investment(manufacturer and retailer invest in CSR).Under cap-and-trade regulation,considering manufacturers,retailers and third parties respectively recycle waste products,and using Stackelberg game method establishes closed-loop supply chain models that takes the manufacturer as the core.The CSR investment level,carbon transaction price,carbon emission reduction and promotion cost ratio are introduced into the two CSR investment models,and the manufacturer’s CSR investment share ratio is introduced again in the CSR co-investment model.A comparative analysis of the impact of the CSR investment of each enterprise member on the channel members’ recycling and emission reduction decisions.The main conclusions are as follows:(1)From the point of view of improving the recovery rate of waste products: It is found that when manufacturer or retailer makes CSR investment or manufacturer and retailer make CSR investment,and it is best for each enterprise member to implement CSR when the manufacturer recycles waste products,that is,the recovery rate is the highest.(2)From the perspective of reducing carbon emissions: the cost of remanufactured products is less Under independent investment of CSR,the level of emission reduction and low-carbon promotion effort are the highest when retailer recycles,on the contrary,they are the highest when manufacturer recycles.Under joint investment of CSR,the level of carbon emission reduction is the highest when manufacturer recycles,the level of low-carbon promotion effort is affected by the cost savings of manufacturers’ remanufactured products and the proportion of CSR investment.(3)Under different CSR investment modes: Under independent investment of CSR,the manufacturer can adjust the recovery situation to get the highest profit according to enterprise members make CSR investment and the cost of remanufactured products.Under joint investment of CSR,the manufacturer’s profit is the highest when the retailer recovers;regardless of CSR independent investment or CSR joint investment,the retailer’s profit and system social welfare are the highest when the manufacturer recovers.(4)In the case of manufacturer recycling,comparing the two modes of CSR independent investment and CSR co-investment,it is found that if the proportion of manufacturers’ CSR investment is small,the waste recovery rate,carbon reduction level and low-carbon promotion effort level are the highest under the joint investment of CSR,on the contrary,the waste recovery rate,carbon reduction level and low-carbon promotion effort level are the highest under the retailer investment CSR.If the low-carbon promotion cost coefficient is small,the manufacturer’s profit is the highest when the retailer invests in CSR,on the contrary,the manufacturer’s profit is the highest under the joint investment of CSR,and the retailer’s profit and system social welfare are the highest under joint investment of CSR.
