Abstract: Abstract: 【Objective】In order to harmonize conflict between the existing deforestation management system including the deforestation quota management and license and the marketing of forestry right reform, the carbon tax system controlling carbon emission may change the administrative management system of deforestation. 【Method】This paper introduce the concept of forestry carbon tax to the existing commercial forest deforestation management system, and quantitative analysis on forestry carbon tax from deforestation link for commercial forest deforestation involves carbon emissions with the help of general equilibrium(CGE)model. Forest carbon emissions and forest carbon tax rate zone were measured, and the five the tax situation simulated the forestry carbon tax at 5, 10, 20, 30, 40 yuan /m³ affect on forestry investment, forestry expenditure, carbon emissions, each sector income.【Result】In order to describe the controllability on deforestation volume of forestry carbon tax, the CGE model of forestry carbon tax is composed of two parts: production module and economic subject module. Production module include three kinds of equation of forest product flow, cultivation of forest resources, the market aggregate supply. Economic subject module describes the income and expenses of every economic subject, as well as the mutual transfer payments. In a set of 5 kinds of forestry carbon taxes, when forestry carbon tax is 20-30 yuan/m³, the forestry investment and expenditure, carbon emissions and the income of each sector change in the best. And the forestry carbon tax should be designed in four aspects, including the purpose, regulation effect, ownership and basic principle of taxation.【Conclusion】Forestry carbon tax revenues could balance Lumber logging, the forestry carbon taxes applied to compensate for the reduction of wood cutting, and should adhere to the principle of incentive and constraint, step-by-step rate setting and dynamic adjustment, discrimination to different forest region and reasonable reference.
