摘要

In response to global climate change, according to the policy attributes of carbon taxes and carbon trading, the paper designs two emission reduction scenarios, single carbon tax and the joint use of carbon tax and carbon trading, and builds the computable general equilibrium (CGE) model to simulate and analyze their impacts on China's economy under three kinds of emission reduction target in two scenarios. The results showed that: the single carbon tax scenarios an produce the negative influence with different degree on both whole economy and 11 major economic sectors; Introduce carbon emissions trading into model, the results shows it will slow down the impact of carbon tax on China's economy and has a positive effect on the low carbon energy sectors. The emission reduction policy of combination of carbon tax and carbon trading are more in line with China's actual condition.
