摘　　要：本文以一个制造商和一个零售商组成的二级低碳供应链为研究对象,以低碳供应链政府补贴策略为研究主题,政府投资建设区块链技术应用平台,供应链企业有偿使用区块链技术。在此背景下,考虑消费者低碳偏好和绿色信任,建立了区块链技术应用前后减排技术投入补贴和低碳产品产量补贴四种情境下的政府主导,制造商和零售商跟随的三阶段博弈模型,通过比较四种情境下的最优社会福利、碳减排率和低碳产品产量,探讨了政府低碳补贴策略的最优问题。研究发现,当消费者低碳偏好系数与绿色信任系数之积大于某一固定值时,政府通过产量补贴能获得更高的社会福利,且更能促进企业减排;政府通过产量补贴始终能促进低碳产品需求。当减排成本系数趋近无穷大时,政府实施产量补贴时的低碳产品需求是实施技术补贴时的4倍;当区块链平台单周期分摊成本和企业应用区块链技术单位成本小于某一阈值时,政府建设区块链平台能获得更高的社会福利,促进企业减排并提高消费者低碳产品需求。With the continuous progress of China's economy and society,green development has become a national strategy,and carbon emission reduction is an important measure.The government can promote the investment of enterprises'emission reduction technology and increase social welfare through moderate lowcarbon subsidies to enterprises.The introduction of block-chain technology into the low-carbon supply chain can improve the coordination degree of low-carbon decision-making among the main bodies of the supply chain and promote the emission reduction of enterprises.Therefore,it is of great significance to study the government subsidy strategy of low-carbon supply chain based on block-chain technology.In this paper,a two-level lowcarbon supply chain composed of a manufacturer and a retailer is taken as the research object,and the govern⁃ment subsidy strategy of the low-carbon supply chain is taken as the research topic.The government invests in the construction of the application platform of block-chain technology,and the supply chain enterprises pay to use the block-chain technology.Under this background,considering consumers'low-carbon preference and green trust,this paper set up before and after the application block chain technology under R&D investment subsidy policy or output subsidy policy of these four situations of three stages Stackelberg game models,in which the government takes the lead and manufacturers and retailers follow and the government to the social welfare maximization as the goal,manufacturers and retailers in order to maximize their own interests as the goal,through comparing the four kinds of situations of the optimal rate of social welfare,carbon reduction and low carbon product production,discusses the government low carbon subsidies strategy of optimal problem.And the validity of the results is verified through the analysis of examples.The results show that when the product of consumers'low-carbon preference coefficient and green trust coefficient is greater than a certain fixed value,the gove
