摘　　要：针对由制造商、零售商和消费者构成的低碳供应链,文章考虑了制造商减排积极性的随机动态特征,研究了消费者具有绿色信任和低碳偏好背景下供应链成员的微分博弈.利用伊藤过程对制造商减排积极性的随机演化过程进行刻画,并基于成员的利润结构,构建了采用和不采用区块链技术两种情形下低碳供应链的随机微分博弈模型.运用贝尔曼连续型动态规划理论,求解了两种情形均衡状态下成员的反馈策略,揭示了制造商减排积极性的随机动态演化特征.最后结合算例,分析了稳定和动态均衡状态下制造商减排积极性、消费者特征参数以及随机干扰因素对成员均衡决策和最优利润的影响.研究表明:受到随机干扰因素的影响,制造商减排积极性始终围绕其期望上下波动,最终稳定于一个稳态值,减排积极性的提高和消费者低碳偏好程度的提高,都能为制造商带来经济效益.采用区块链技术更有利于提高零售商的获利水平,而制造商是否采用区块链技术需要同时考虑消费者低碳偏好程度和绿色信任程度的影响.Aiming at a low-carbon supply chain composed of a manufacturer,a retailer and consumers,this paper considers the stochastic dynamic characteristics of the manufacturer's enthusiasm for emission reduction,and studies the differential game between two suppliers under the background of consumers'green trust and low-carbon preference.The stochastic evolution process of the manufacturer's enthusiasm for emission reduction is described by using Itôprocess.Based on the profit structure of members,the stochastic differential game model of low-carbon supply chain with and without blockchain technology is constructed.By using Bellman's continuous dynamic programming theory,the feedback strategies of members in two equilibrium situations are solved,and the stochastic dynamic evolution characteristics of the manufacturer's enthusiasm for emission reduction are revealed.Finally,a numerical example is given to analyze the influence of the manufacturer's enthusiasm for emission reduction,consumers'green trust and low-carbon preference,as well as stochastic disturbance factors on members'equilibrium strategy and optimal profit under stable and dynamic equilibrium conditions,The results show that,due to the influence of random interference factors,the manufacturer's enthusiasm for emission reduction always fluctuates around its expectation,and finally stabilizes at a steady-state value.The improvement of manufacturer's enthusiasm for emission reduction and consumers'low-carbon preference can bring economic benefits to the manufacturer.The adoption of blockchain technology is more conducive to improving the profitability of the retailer,and whether the manufacturer adopts blockchain technology needs to consider the influence of consumers'low-carbon preference and green trust.
