Research On Supply Chain Low-carbon Strategy Based On Carbon Trading Policy And Consumer Low-carbon Preferenc

The massive emission of greenhouse gases,represented by carbon dioxide,has many negative effects on climate,ecology and human health,and has become a threat to humanity.The carbon emission trading policy(CET)is an action in this context,and enterprises are the actors directly involved in the trading.At the same time,the low carbon awareness of consumers are gradually generated,demanding green products and low-carbon supply chain from the market side.The new policy context and market characteristics will have an important impact on the optimal strategy of supply chain enterprises.In view of this,this paper investigates the systemic equilibrium strategies in different contexts by considering consumers with low carbon preferences in the context of carbon trading policy and applying game theory,consumer preference theory and numerical simulation methods.Firstly,two supply chain structures,single manufacturer and single retailer,and single manufacturer and two retailers,are constructed,and three game models,namely,no investment in emission reduction,separate investment in emission reduction by manufacturer,and joint investment in emission reduction by manufacturer and retailer(s),are built under the two structures according to the strategies that the manufacturer can adopt.The pricing decisions and green innovation decisions of the supply chain members are solved.Secondly,the equilibrium strategies under each decision model are compared horizontally to study the impact of supply chain relationships on supply chain performance under the given structure,including product price,product low-carbon level,member profit and system profit.Finally,the influence of four parameters(price sensitivity coefficient,low-carbon sensitivity coefficient,carbon emission trading price,and green innovation cost)on supply chain decision making is investigated,and the pattern is visualized through numerical analysis.The main conclusions of this paper are as follows:(1)centralized decision making can significantly avoid the efficiency waste caused by the double marginal effect of the supply chain and can mitigate the negative impact of external factors on the system;(2)the advantages and disadvantages of the retailers’ cost reduction sharing mechanism are related to the supply chain structure,and when multiple retailers exist and form an alliance,even if they will provide cost reduction sharing to the upstream,it will harm the manufacturers’ interests;(3)consumer low-carbon preferences provide competitive access to supply chains beyond price,and firms are able to obtain higher profits through low-carbon premiums and market expansion;(4)in markets with low-carbon preferences,the additional costs brought by carbon trading policies to firms can be covered by the profitability of product decarbonization,driving the low-carbon transformation of supply chains.
