Research on Pricing Decisions of Closed-Loop Supply Chain Based on Carbon Trade and Old-for Remanufacturing Subsidy
Improper disposal of waste products caused severe pollution.Reducing carbon emissions has become a topic of general interest,government introduced policies to guide enterprises in recycling and remanufactur-ing.Old-for Remanufacturing Subsidy and Carbon trading mechanism are effective measures to foster recycle and remanufacture and decrease carbon emission,3 closed-loop supply chain models based on the implemen-tation of these 2 policies are constructed.Model 1:Carbon trading mechanism;Model 2:Old-for Remanu-facturing Subsidy mechanism;Model 3:Carbon trading combined with Old-for Remanufacturing Subsidy mechanism.This paper studied the impact of Old-for Remanufacturing Subsidy and Carbon trading mechanism on price decisions,profit and carbon emission.The results show that:①Under carbon trading mechanism,with the increasing of carbon trading price,the wholesale price and price of the new product will increase,the demand of initial consumers for new products decreases,and the demand for remanufactured products increases.The de-mand of swap consumers for new products decreases and the demand for remanufactured products increases.Profit of retailer and carbon emission drop down.②Under Old-for Remanufacturing Subsidy mechanism,With the increase of Old-for Remanufacturing subsidy,the wholesale price and price of the new product will remain stable,the wholesale price and the price of the re-manufactured product will increase,demand of initial consum-er for new products increases,demand for remanufactured products decreases.The demand of swap consumers for new products decreases and the demand for remanufactured products increases.Profit of retailer and manu-facturer increase,carbon emissions of the supply chain are decreasing.③Comparing with the two single mecha-nisms,the dual mechanism is more conducive for increasing consumer demand for remanufactured products,manufacture'rs profit and the total carbon emissions of the supply chain.
