Research On Green Supply Chain Pricing And Government Subsidy Strategies Considering Blockchain

With the development of economy,the problem of environmental damage is becoming more and more serious.Countries all over the world pay more and more attention to the development of green supply chain.In promoting the development of green supply chain,government subsidies are a favorable way,but there are still problems in the green supply chain,such as information cannot be coordinated and accurate access.To solve these problems,blockchain is an effective means.Blockchain technology can help improve the information transparency of the supply chain,so that enterprises can avoid the cost caused by information asymmetry,and improve the benefits of enterprises.Therefore,based on the background of green supply chain,it has important theoretical and practical application value to study how to maximize the benefits of supply chain members under the dual influence of blockchain technology and different government subsidy strategies.Based on relevant research results and practical experience at home and abroad,this paper adopts the research method combining theoretical analysis and numerical simulation,and uses Stackelberg game to solve the problem of green supply chain pricing decision and government subsidy strategy selection.First,different government subsidy models are constructed according to common government subsidy strategies,and three models of government subsidy,greenness subsidy and price subsidy without blockchain technology are analyzed.Secondly,in the case of considering blockchain technology,analysis of the adoption of blockchain technology anarchic subsidy,greenness subsidy,price subsidy model.Finally,by comparing the pricing and profit,product greenness and social welfare of supply chain members under the models of anarchy subsidy,greenness subsidy and price subsidy before and after the adoption of blockchain technology,this paper studies the influence of blockchain technology and different government subsidy strategies on the pricing decision of green supply chain and the selection of government subsidy strategies.It is found that,regardless of whether blockchain technology is adopted or not,the optimal pricing and profit under price subsidies are the highest.When the sensitivity coefficient of consumers to product greenness and the coefficient of green research and development cost meet a certain threshold,the greenness of products under the subsidies is the highest.When the sensitivity coefficient of consumers to product greenness is greater than a certain threshold value,the social welfare under the price subsidy is the highest.By comparing different subsidy strategies,it can be seen that under certain conditions,greenness subsidy can better stimulate the improvement of product greenness,but in this case,the profit of supply chain members is not optimal.Under price subsidy,although the product greenness is not optimal,the profit of supply chain members is optimal.The optimal pricing under anarchic subsidy and greenness subsidy is higher when using blockchain,but in the price subsidy mode,the pricing with blockchain will be higher only when the unit cost of applying blockchain technology is less than a certain threshold.When the unit cost of applying blockchain technology is less than a certain threshold value,the profit and product greenness of supply chain members adopting blockchain technology under the three kinds of subsidies are higher.When the single-cycle apportionment cost of blockchain platform is less than a certain threshold value respectively,the government can obtain higher social welfare when investing in the construction of blockchain platform under the three subsidy modes.This requires companies to focus on the critical point of balancing benefits and expenses before deciding whether to introduce blockchain.At the same time,the government should intervene in time.It can reduce the input cost of the blockchain platform or prolong the service cycle as much as possible through operation and maintenance monitoring,research and development,and indirectly improve social welfare.
