摘　　要：在全球气候变化的背景下,已有150多个国家制定了减碳政策。通过构建Stackelberg政企博弈模型,探究碳税和碳交易制度对企业减排决策、企业收益及社会总福利的影响。研究发现,碳交易制度中的碳交易价格和碳税制度中的碳税率及其增长率是决定企业减排策略的直接因素,而碳交易制度中的碳排放配额则因为规则限制间接影响企业减排策略。同时,研究提供了2种制度下的企业最优减排决策相同时,使社会总福利更高的政策决策方案。最后,数值仿真部分为钢铁行业减排政策的选择提供了数据支撑。企业积极投资低碳技术,同时政府根据行业特性实施差异化的混合碳政策,可增进社会总福利并推动企业的绿色转型。In the context of global climate change,more than 150 countries have formulated carbon reduction policies.By constructing the Stackelberg government-corporate game model,we explore the impacts of carbon tax and carbon trading system on corporate emission reduction decisions,corporate earnings and total social welfare.It is found that the carbon trading price in the carbon trading system and the carbon tax rate and its growth rate in the carbon tax system play a direct role in corporate emission reduction strategies,while the carbon emission quotas in the carbon trading system indirectly affect corporate emission reduction strategies because of the rule restrictions.At the same time,the study provides the policy decision scheme that makes the total social welfare higher when the optimal corporate emission reduction decision is the same in both regimes.Finally,the numerical simulation part provides data support for the choice of emission reduction policies in the iron and steel industry.The study concludes that firms are encouraged to actively invest in low-carbon technologies,while the government is recommended to implement differentiated mixed carbon policies based on industry characteristics to enhance total social welfare and promote green transformation of firms.
