Low-carbon cooperation among cloud manufacturing service providers is one way to achieve carbon peak and neutrality. Such cooperation is related to the benefits to service providers adopting low-carbon strategies and stochastic factors such as government low-carbon policies, providers' environmental awareness, and demanders' low-carbon preferences. Focusing on the evolutionary process of service providers' low-carbon strategy selection under uncertain factors, a stochastic evolutionary game model is constructed based on the Moran process, and the equilibrium conditions for low-carbon cooperation among providers are analyzed under benefit-dominated and stochastic factor-dominated situations. Through numerical simulation, the effects of the cloud platform's cost-sharing coefficient for low-carbon investment, matching growth rate, carbon trading price, and group size on providers' low-carbon strategy evolution are analyzed. The research results show that increasing the cloud platform's low-carbon cost-sharing, carbon trading price, and group size can promote low-carbon cooperation among service providers. With greater low-carbon investment costs and greater stochastic factor interference, the providers' enthusiasm for low-carbon cooperation decreases. This study fills the research gap in the low-carbon cooperation evolution of cloud manufacturing providers based on the stochastic evolutionary game and provides decision-making suggestions for governments and cloud platforms to encourage provider participation in low-carbon cooperation and for providers to adopt low-carbon strategies.
低碳合作是云制造服务提供商实现碳达峰和碳中和的途径之一。这种合作关系涉及到服务提供商采用低碳策略的利益以及政府低碳政策、提供商的环境意识和需求方的低碳偏好等随机因素。本文聚焦于不确定因素下服务提供商低碳策略选择的演化过程,基于 Moran 过程构建了一个随机演化博弈模型,并分析了利益主导和随机因素主导情况下提供商之间低碳合作的均衡条件。通过数值模拟,分析了云平台低碳投资成本分担系数、匹配增长率、碳交易价格和群体规模对提供商低碳策略演化的影响。研究结果表明,增加云平台的低碳成本分担、碳交易价格和群体规模可以促进服务提供商之间的低碳合作。随着低碳投资成本的增加和随机因素干扰的增大,提供商低碳合作的积极性会降低。本研究基于随机演化博弈填补了云制造提供商低碳合作演化的研究空白,为政府和云平台鼓励提供商参与低碳合作以及提供商采取低碳策略提供了决策建议。
