The Impact of Energy Tax on Carbon Emission Mitigation: An Integrated Analysis Using CGE and SDA

By originally integrating the structural decomposition analysis (SDA) into a computable general equilibrium (CGE) model, this paper simulates and analyzes impact mechanism of energy taxes on carbon emissions. Changes in dioxide emissions, consumption structure, other macroeconomic variables are investigated under different pre-set scenarios. The conclusion shows that imposition an ad valorem tax will indeed production enterprises. A higher rate leads to more pronounced reductions intensity effect is dominant factor driving national emissions emission decline. Although structure final demand play role, their influences relatively weak. While levying taxes, subsidies for personal income or corporate can achieve double dividends. progress utilization technology capable increasing unit output easing negative collection, gross product may rise rather than fall. Under circumstance, greater role because total coefficients various industries industry products further Only by coal oil, exempting natural gas, using revenue subsidize investment gas government optimize structure. Subsidies boost mining processing increase share cleaner source which critical current transition process.
