在两国自由贸易的市场结构下，构建了政府碳补贴政策选择与企业碳减排选择的三阶段博弈模型，研究一国已开征碳税后，继续实施碳补贴政策对本国和外国企业产量、利润的影响。发现碳补贴政策能够激励企业进行碳减排技术的研发，提高本国的碳减排技术水平，并且实施碳补贴政策能够增加本国企业在共同市场上的市场份额和利润，有利于本国企业的可持续发展。%In the free trade market structure, a three-stage game model is constructed for the government and the firm. In this model, the government could choose to implement carbon subsidy policy and the firm to put into effect carbon abatement. Analyzing the impact of carbon subsidy policy on the productions and profits of domestic and foreign firm when carbon tax policy has been used, we have found that carbon subsidy policy could urge the domestic firm to improve its carbon abatement technology and increase its market share and profits. In short, carbon subsidy policy is good for the sustainable development of the domestic firm.
