考虑区块链技术及政府补贴的绿色供应链定价决策研究

Research on Green Supply Chain Pricing Decision Considering Blockchain Technology and Government Subsidies

本文以政府、绿色制造商和零售商组成的三级绿色供应链为研究对象,引入政府对绿色产品的绿色补贴因子,基于区块链技术的溯源水平因子,运用Stackelberg博弈进行理论建模,并运用数值仿真方法进行分析。研究表明:制造商通过积极的区块链技术,提升相应的溯源水平,市场潜在需求不断扩大,高社会福利水平得到提升,制造商及零售商利润也在增大;消费者溯源水平敏感系数对决策变量以及供应链成员的绩效均有正向促进效应;随着消费者绿色偏好敏感系数的增加,政府绿色补贴的比例会减小,绿色供应链转型更为有效与主动。

The paper takes the three-level green supply chain consisting of the government,green manufacturers,and retailers as the research object.introducing the factors of government green subsidies for green products and the traceability level based on blockchain technology.The paper also uses the Stackelberg game for theoretical modeling and carries out analysis using the numerical simulation method.Research has shown that through active blockchain technology,manufacturers can improve their traceability level,continuously expand the potential market demand,enhance the level of social welfare,and increase profits for manufacturers and retailers.The sensitivity coefficient of consumer traceability level positively influences decision variables and the performance of supply chain members.As the sensitivity coefficient of consumer preference for green products increases,the proportion of government green subsidies will decrease,making green supply chain transformation more effective and proactive.
