摘　　要：当中国在第七十五届联合国大会上提出“碳中和、碳达峰”的概念后,金融市场上便开始出现一种新兴的板块——碳中和概念股,其主要行为主体有政府、企业和股民。为研究这三方的相互关系以及对碳中和概念股的影响,通过构建三方演化博弈模型,利用复制动态方程分析三方主体博弈间的稳定行为策略,并运用Matlab软件对方程进行数值仿真,以验证模型分析的结果。研究表明:政府支持和企业自主发行都会影响股民对碳中和概念股的购买行为,但股民在购买概念股时,政府是否参与是一项更为重要的参考依据。通过这项博弈研究,进一步了解了碳中和概念股在市场发展中不同行为主体之间的相互关联,其中政府的参与及支持具有关键性引导作用,在此基础上还需各方的协同合作,才能促进碳中和概念股在金融市场上的正向发展,让低碳环保理念在各个领域全面开花。When China put forward the concept of"carbon neutralization and carbon peak"at the 75th United Nations General Assembly,carbon neutrality stocks,a new sector,appeared in the financial market,whose main action subjects are the government,enterprises and shareholders.In order to study the relationship between the three parties and their influence on the carbon neutrality stocks,a three-party evolutionary game model was constructed,and the stable behavior strategy between the three parties was analyzed by replicator dynamic equation,and the numerical simulation of the equation was conducted by Matlab software to verify the results of the model analysis.The research shows that both government support and independent issuance of enterprises will affect shareholders'purchase behavior of carbon neutrality stocks,but whether the government participates in or not is a more important reference.Through this game study,the paper further understands the correlation between different action subjects of carbon neutrality stocks in market development,among which the support of the government plays a key guiding role.On this basis,it also needs the cooperation of all parties to promote the positive development of carbon neutral concept stocks in the financial market and promote and spread the concept of low-carbon environmental protection in all aspects comprehensively.
