| Due to China’s commitment to the world at the Copenhagen Climate Summit,by 2020,the carbon emissions per unit of GDP will be reduced by 40% to 45% on the basis of 2005.In this context,a low-carbon economy is born.As an important carrier of global “carbon”flows,supply chain low carbonization is of great significance for global carbon reduction and must be taken seriously.The competition between enterprises and enterprises is not only the competition of prices,but also the competition of supply chains.This paper mainly studies the two-level multinational supply chain consisting of one manufacturer and two retailers,and establishes the leader’s leadership role in the stackelberg game model.Assuming the existence of low carbon preferences and different market sizes,the theory explores the impact of different low carbon policies,consumer low carbon preferences,market size on supply chain enterprise decision-making,and numerically simulates the optimal supply chain members in specific situations.Changes in decision-making and changes in profits,the study found that according to the impact of low-carbon policies and consumer low-carbon preferences on manufacturers’ profits,Chinese manufacturers will choose B countries(small countries that implement carbon tariff policies)retailers as their own distributors Selling products.Manufacturers should try to occupy large markets to distribute products in order to pursue higher profits.Retailers 1 in the big country market should increase the order quantity of low-carbon goods and common products to distribute in order to pursue higher profits.When the retailer 2 in the small country market chooses the wholesaler,if the wholesaler already occupies a market with high consumer preference and large market size,the retailer 2 is more willing to cooperate with it to order goods.Finally,this paper puts forward several policy recommendations on the three aspects of government,enterprises and consumers. |
