Abstract：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.
