Research on the Emission Reduction Effect of Carbon Tax and Sulfur Tax in Henan Province Based on Dynamic CGE Model
China has promised that the carbon emission would peak at 2030 and be neutral at 2060.How to realize the carbon peaking and neutral by carbon reduction is a significant matter.Research on the emission reduction effects of carbon tax and sulfur tax from a regional perspective has great significance on achieving carbon emission reduction targets.Taking Henan Province as an example,this study constructs a 42-sector dynamic CGE model and analyzes the emission reduction effects of carbon tax and sulfur tax through scenario analysis.The research results show that under the baseline scenario,Henan's economy maintains an stable growth trend and carbon emissions will peak in 2024.When a carbon tax of 100 yuan/ton is imposed,carbon emis-sions are lower than the baseline scenario,and the economic loss is quite small.Sulfur tax has a slight promotion effect on car-bon emission reduction.At the same time,levying carbon tax and sulfur tax at the same time has the largest emission reduc-tion,with greatest total output damage.From the industrial perspective,levying carbon tax and sulfur tax have greater nega-tive impacts on the primary and secondary industries,while boosting effects on the tertiary industry,giving an implication that carbon tax and sulfur tax can promote the adjustment of the industrial structure of Henan province.
