考虑区块链和政府补贴的绿色供应链决策

Green Supply Chain Decisions Considering Blockchain and Government Subsidies

在由一个制造商和一个零售商组成的二级绿色供应链系统中,引入零售商对信息共享的敏感程度、区块链使用程度、单位产品绿色度补贴额及交易费用等影响因素,分析区块链应用及政府补贴对绿色供应链定价决策和利润的影响。研究表明:无论零售商是否引入区块链,政府对制造商绿色产品补贴时的产品价格、产品绿色度、制造商和零售商的利润均大于不补贴时的情形。无论政府是否提供绿色产品补贴,当引入区块链技术节省的交易费用较大时,引入区块链时的制造商利润要高于不引入的情形。而当区块链使用程度较高或区块链技术固定投入成本较低时,零售商利润要高于不引入的情形。

In a secondary green supply chain system consisting of a manufacturer and a retailer,factors such as the sensitivity of retailers to information sharing,the degree of blockchain usage,the amount of green subsidy per unit product,and transaction costs are introduced to analyze the impact of blockchain applications and government subsidies on green supply chain pricing decisions and profits.Research has shown that regardless of whether retailers introduce blockchain,the government’s subsidies for green products from manufacturers result in higher product prices,greenness,and profits for both manufacturers and retailers than those without subsidies.Regardless of whether the government provides subsidies for green products,when the introduction of blockchain technology saves significant transaction costs,the manufacturer’s profit is higher when the blockchain is introduced than when it is not introduced.However,when the use of blockchain is high or the fixed input cost of blockchain technology is low,the profit of retailers is higher than that of non-introduction.
