Research On Supply Chain's Emission Reduction And Pricing Policies In Low Carbon Environment

With the continuous expansion of the world economy,the ecological environment has been severely damaged.In order to achieve sustainable development,countries have introduced policies to reduce carbon emissions.The report "Status and Trend of Global Carbon Market Development in 2016" shows that 36 countries,more than 20 regions,states,and cities have implemented carbon trading policies.In December 2017,China's National Development and Reform Commission announced that it will soon launch a national carbon emissions trading system.With the gradual improvement of consumers' low-carbon awareness,the carbon emissions of products have become more and more important in the market demand for products.Due to the dual impact of low-carbon regulation and market demand,emission reduction has become an inevitable trend in supply chain operations.A large number of studies have proved that "people"are not completely self-interested,but have social preferences.They care about their own material interests as well as the harmonious concerns of their partners.Like economic incentives,social preferences are also effective motivating factors that affect individual behavior.Positive social preferences can promote cooperation and improve the efficiency of supply chain coordination.In addition,the information asymmetry between members of the supply chain will create an imbalance of interest,which is an important factor affecting corporate decisions.Social preferences of decision makers also affect information sharing among supply chain members.Based on the above background,this paper mainly focuses on the following two aspects:First,with a single supplier and a single manufacturer as the research object,the study of information sharing decision-making,pricing,and unit commodity emission reduction decision-making for supply chain members under carbon trading regulations is conducted.Analyze the impact of information asymmetry on business decisions and profits.The study found that when the manufacturer's emission reduction efficiency is low,manufacturers will choose to conceal their abatement cost information to obtain higher profits.For suppliers,manufacturers do not share emission reduction cost information with them to reduce their profits;when manufacturers' emission reduction cost efficiency is low,information asymmetry of abatement costs will increase their emission reductions per unit of product.Moreover,regardless of whether emission reduction cost information is fully shared or not,the level of consumers' low-carbon awareness,carbon emission pricing prices,supply chain member emission reduction efficiency,and information uncertainty are consistent with the influence of supply chain member decision-making and profit.Second,in the low-carbon supply chain consisting of a single manufacturer and a single supplier,the factors of social preference are introduced.There are social preference factors,information sharing decisions of the supply chain members,pricing and decision-making for reduction of the unit commodity.The study found that,as in the case of carbon trading regulations.,when manufacturers' emission reduction efficiency remains at a moderate level?manufacturers will conceal information on abatement costs.For supplers,when the manuf-acturer's abatement cost ef-ficiency is low,the existence of asymmetric abatement cost information will increase its emission reductions and performance per unit of commodity.Moreover.,when social preferences exist,asymmetric information on abatement costs does not change consumer preference for low-carbon products,supply chain members' emission reduction efficiency,social preference coefficient,and uncertainty of information to supply chain member decisions and profits.mechanism.Studies have shown that social preferences change the consumeris low-carbon awareness,and the effect of supply chain member abatement efficiency on commodity pricing.
