The Study Of The Carbon Tax Policy Effect And The Optimal Tax Rate In The Industry Of Our Country

At present, our country has become one of the countries which have the largest energy consumption and carbon emissions. Faced with international pressure for the development of low carbon economy. Therefore, under the new economic norm,planning from a single target that the total control target and emission reduction target into dual targets that the improvement of environmental quality and pollutant emission control, involving the green economy, nuclear safety, soil environment protection, ecological environment protection, water prevention,control of environmental pollution and other aspects. As promoting energy, economy and environment coordinated sustainable development and the most important measure of market efficiency, carbon tax not only help promote energy conservation,emissions reduction and promote green development, but also conducive to the well-being of the people’s livelihood, therefore it has attracted much attention.There are many research on carbon tax policy at home and abroad, CGE model is the mainstream of policy analysis tool. Based on the literature review in detail,based on the input-output table in 2007, such as the introduction of energy input and carbon emissions data, compiled the macro CE3-2007 SAM table. In constructing a set of energy, economy and environment for the integration of the computable general equilibrium(CE3-CGE) model, according to the need this paper has introduced the elements of fossil carbon input module, the expected output of the module, the energy and environment policy variables that a carbon tax module,dynamic module and connecting with the capital accumulation. This paper has explained a series of effects of the carbon tax rate on macroeconomic and simulated the carbon emissions reduction targets under different carbon tax rate of 25 the effects of industrial sectors, including the output effect, energy structure and import and export trade structure adjustment effect, energy conservation and emissions reduction effect and social effect.Besides, this paper has predicted for the optimal bands of carbon taxes in 2020.Research has shown that a carbon tax would increase the cost of high carbon enterprise, reduce the level of output, adjust into exports, but for the influence of low carbon enterprise ineffective.At the same time, the consumption of coal and oil from the carbon tax policy consumption proportion are declining, and in the short term,the consumption of natural gas will decreased,but in the long run due to technological progress its consumption showed a trend of growth. In addition,employment, residents income and welfare all showed a trend of decline after rising first. Finally, determine the optimal tax rate of China is a dynamic gradual process,the optimal tax rate should be between 40 yuan/ton-70 yuan/ton.
