Research On Operation Strategies Of Two Competitive Supply Chains Based On Blockchain

In the context of global digitization,blockchain technology has facilitated the development of supply chains.The existing research on supply chains under blockchain technology has mainly focused on one supply chain,however,research on two competing supply chains under blockchain technology is relatively scarce.In the context of global warming,it is imperative to reduce carbon emissions.Since blockchain technology can increase the trust among supply chain members and promote collaborative emission reduction among supply chain members.Therefore,it is especially important to study the collaborative emission reduction of supply chain members by blockchain technology for carbon reduction.Based on the above,firstly,we study the conditions for the introduction of blockchain technology in two supply chains and how the supply chain enterprises adopt blockchain technology to formulate their operation strategies,and further compare and analyze the relationship between the optimal strategies of the three models;secondly,we construct three models based on the premise of whether "Blockchain+Collaborative Emission Reduction" is introduced in two supply chains,and we analyze the impact of "Blockchain+Collaborative Emission Reduction" on the carbon reduction rate of supply chain members and the total revenue of the supply chain.The main contents of the paper are as follows:Three models are built: neither of the two supply chains adopts blockchain technology,both supply chains adopt blockchain technology as well as one supply chain does not use blockchain technology,and the other supply chain does.Stackelberg game is played between the manufacturer and retailer in each supply chain,the Cournot game is played between two retailers competing for order quantity,and the Bertrand game is played between two manufacturers competing for wholesale price.The optimal retail price,wholesale price and supply chain revenue of each model are obtained.The optimal strategies of the three models are compared and analyzed.Secondly,the strategy selection of two supply chains is regarded as a bimatrix game,and the Nash Equilibrium of the bimatrix game is solved to obtain the conditions for the two supply chains to choose the blockchain technology.Finally,the influence of blockchain operation cost and supply chain competition coefficient on supply chain strategy selection and benefits is further analyzed by a numerical example.The results show that the two competing supply chain equilibrium strategies are affected by the cost of blockchain.This article studies the issue of strategy selection for two competing supply chains under the concept of "Blockchain+Collaborative Emission Reduction",and constructs three models: neither supply chain adopts "Blockchain+Collaborative Emission Reduction",both supply chains adopt "Blockchain+Collaborative Emission Reduction",one supply chain does not adopt "Blockchain+Collaborative Emission Reduction",and the other supply chain adopts "Blockchain+Collaborative Emission Reduction".Numerical analysis is used to analyze the strategy,Analyze the impact of the competition coefficient between low-carbon products in the supply chain,the sensitivity coefficient of demand to low-carbon promotion,on the carbon reduction rate of supply chain members and the total revenue of the supply chain.
