Carbon tax is one of ways to cut the emissions of GHG, which has already been employed by the west. To study the effect of carbon tax on energy conservation and carbon reduction in China, a new model is constructed based on dynamic CGE model and the linkage of dynamic CGE model and energy technology model. Besides the improvement of technology of energy, if carbon taxation is employed, the goal to reduce its carbon intensity by 40% by 2020 compared with 2005 need to levy a tax of 60 yuan at least per tonne, the simulations of this tax to carbon reduction, economic and income of residents are analysed under different circumstances, the results shows that there is a great impact on income of residents and GDP with a higher tax burden level.
