Research On The Imapct Of Carbon Tax On The Competitiveness Of Coal-based Power Enterprises

As the world's largest carbon emitter,China faces an urgent need for emission reductions.Electric power is an important pillar of the economy,but also a industry with large energy consumption,serious pollution and high emissions.Research shows that the carbon emissions of the power generation industry accounted for 4.1% of the total carbon emissions in 2014,about14.426 billion tons.In which,92.7% belongs to coal electricity,showing an increasing trend year by year.Therefore,it is of great significance to study the impact of carbon tax on the competitiveness of coal electricity enterprises.The main body of this paper is divided into five parts.The first part is the theoretical part of the article,which mainly includes the basic theory of carbon tax and enterprise competitiveness.The second summarizes the characteristics of the total amount and trend of carbon emissions in Chinese coal-fired enterprises,and constructs the index system of coal electricity enterprises competitiveness,then,analyzes the current competitiveness of coal-fired enterprises in China.The third part studies the influence mechanism of carbon tax on the competitiveness of coal electricity enterprises,about economy,environment and technology.And this part expects how carbon tax impacts to yield,electricity price,CO2 emission and energy consumption.The fourth part establish carbon tax CGE model,and writes macro and micro social accounts,using China2010 input-output extension table,2011 China Statistical Yearbook,2011 China Financial Yearbook prepared macro and micro social accounts.Finally,drawing on the experience of foreign carbon tax levy,simulate the impact of carbon tax level between ?10-200 per ton on the competitiveness of coal and electricity enterprises.The study shows that the carbon tax will reduce the competitiveness of coal enterprises,and with the increase in carbon tax intensity,the impact of the gradual increase.In the early implementation of the carbon tax,carbon tax intensity is small,so,the impact of coal enterprises smaller.However,in the long run,the carbon tax has a greater impact on the comprehensive competitiveness of coal electricity enterprises.The low energy consumption and low emission environment from carbon tax is conducive to hydropower and nuclear power.The environmental atmosphere is more suitable for nuclear power and hydropower enterprises.When the carbon tax reaches ? 200 per ton,coal enterprises competitiveness decrease by 10.22%.Although the carbon tax can play the role of carbon dioxide emissions,the substantial increasing in fuel costs led directly to the competitiveness of coal enterprises decline.
