Research On Pricing Decision Model Of Dual Channel Supply Chain Under Carbon Tax Policy

With the rapid development of e-commerce,consumers’ consumption channels have expanded from one traditional retail channel to multiple sales channels,and consumers’ channel preferences will have an impact on all aspects of the supply chain.At the same time,consumers’ low-carbon preference attributes become more sensitive in the context of increasingly severe environmental pollution,and several countries have introduced local carbon tax policies to control carbon emissions.In the above context,it is important to study the decision making of dual-channel supply chains under carbon tax policies,considering that consumers have channel preferences and low-carbon preferences.In this paper,based on factors such as carbon tax and consumer preferences,we develop a supply chain pricing decision model for traditional retailers to open online channels or not based on offline channels,and a pricing decision model for e-retailers to open offline channels or not based on online channels,and use game theory and numerical analysis to study the pricing and emission reduction decision problems under different channel structures respectively,and address the impact of consumer channel preferences,The impact of consumer channel preferences,low carbon preferences and carbon tax rates on related decisions is discussed.In the third part of the paper,a supply chain system consisting of a single manufacturer and a single traditional retailer is constructed,and the optimal pricing and emission reduction decisions of each member are investigated and compared in the benchmark scenario where the traditional retailer does not open an online channel.It is found that: the carbon tax policy can promote low-carbon production for environmentally friendly manufacturers,while for polluting manufacturers,the government should set the carbon tax rate within a reasonable range;the optimal carbon emission reduction increases after the introduction of the new channel,the profit of traditional retailers increases,then decreases,and then increases again,and the profit of manufacturers becomes smaller.In the fourth part of the article,a supply chain system consisting of a single manufacturer,a single traditional retailer,and a single e-tailer is constructed,and the optimal pricing and emission reduction decisions of each member are studied and compared in the benchmark scenario where the etailer does not open an offline channel.The study shows that the optimal carbon emission reduction of the manufacturer and the profit of the traditional retailer both increase after the e-tailer opens the offline channel;the profit of the e-tailer increases,then decreases and then increases when the consumer preference for the offline channel of the e-tailer becomes larger compared with the baseline case;the profit of the manufacturer is smaller than the baseline case when the consumer preference for the online channel of the manufacturer becomes larger.This paper expands the research scope of dual-channel supply chain and provides management insights for pricing and reduction decisions of supply chain members,which has important theoretical and practical significance.
