Moderator Effects Of Subsidy And Carbon Tax On Low-carbon Economy

Global climate in 2013 follows a long-term warming trend. Australia, Argentina, New Zealand, China, South Korea. Japan and other countries have experienced their hottest summer. All kinds of signs show that the earth is becoming a hotter place, which also makes the greenhouse effect, watering down in the first decade of the 21st century, attract people’s attention once again. Countries, as part of the three main body of a low-carbon economy, are seeking relevant countermeasures actively to control the emissions of carbon dioxide, to curb the greenhouse effect, to achieve a low carbon economy and economic sustainable development.In the previous literature research, most researchers proposed that carbon tax can effectively reduce the emission of carbon dioxide. However, levying carbon tax to a certain extent can slow down the development of economy, carbon tax subsidies are also recognized by researchers. Some literatures indicate that the combination of carbon taxes and subsidies, can achieve the reduction of carbon dioxide emissions without the decline of economic development level. But, previous studies usually adopt purely theoretical analysis or simulation analysis of carbon dioxide emissions based on a hypothetic carbon tax level. As a result, empirical researches are deficient.To investigate the regulating effect of carbon tax and state subsidies for low carbon economy, we analyze them on micro, meso and macro levels. At the micro level, we build a comprehensive analysis model of the influence of state subsidies and tax production function from the perspective of enterprise production decision, we use the principles of economics method to analyze and offer some related cases. The following conclusions are drawn:from the perspective of the industry, both state subsidies and carbon tax are conducive to the development of low-carbon economy. At the same time, there is a combination of policy optimization area. The national policies are rational allocated in this area, which can bring positive growth of the economy and can lead to reduce carbon dioxide emissions. In the meso level, we analyze the three important industries of the Britain. The following conclusions are drawn:(1) the carbon emissions and economic growth of three major industries present the inverse u-shaped curve relationship. When the economic aggregate is less than$2.7774 trillion, the carbon emissions increase with the increasing economy; when the economic aggregate is more than$2.7774 trillion, the carbon emissions reduce with the increasing economy (2) the industry scale and carbon emissions are in a negative correlation relation, and the effect is significant, the carbon emissions reduce as industry scale rises;(3) carbon tax and state subsidies can influence the carbon emissions of the industry. State subsidies have a promoting effect for the carbon emissions of the industry, and state subsidies have a significantly greater influence of the carbon emissions than the carbon tax. At the macro level, panel data of six major countries are analyzed. The following conclusions are drawn:(1) the per capita carbon emissions and economic growth of one country present the inverse u-shaped curve relationship. Meanwhile, the carbon tax and state subsidies can affect the fixed point and direction of the curve; (2) the proportion of secondary industry and the carbon emissions per capita are in direct ratio relation. The greater the proportion of secondary industry is. the larger the carbon dioxide emissions are. However, carbon tax and state subsidies policy can effectively adjust the industrial structure and the influence of factors on carbon emissions effect; (3) the establishment of the carbon tax should be targeted, which means that formulate specific taxes for specific industry. Make carbon tax adjustment a positive impact; (4) the state subsidies have a promoting effect for the carbon emissions, while the existence of a carbon tax can effectively weaken the impact.
