The Co₂ Emission Reduction Effect Of The Industrial Structure Optimization In China

Now, the issue of global climate change has become the focus of research, and the study of greenhouse gases emission has been favored by domestic and foreign scholars. Greenhouse gas emissions of China are more than any other country, and how to reduce carbon dioxide emissions has become a primary problem we are facing.This paper firstly use reference method IPCC provided to estimate Carbon dioxide emissions of the six areas and nationwide and then compared between regions; and then use the LMDI decomposition method to decompose the influence factors of carbon dioxide emissions into economic activity effect, population scale effect, industrial structure effect, the energy intensity (energy saving technology effect) energy structure effect and carbon emission coefficient effect and then analyze the effect of industrial structure; and then panel data was analyzed by STIRPAT to find out elastic trend and verified the existence of carbon dioxide Kuznets curve (CKC curve).The results show that:China’s carbon dioxide emissions is showing a trend of rapid growth, especially in East China area, and in all departments, the process of industrialization is the main motive force of promoting the increase in carbon dioxide emissions; industrial structure influence on carbondioxide emissions is not obvious, so there is still a lot of improvement space and it is also an important cause of high CO2 emissions in China. The industrial structure effect of the first industry can curb carbon dioxide emissions; the industrial structure effect of Industry and construction industry led to the obvious increase in carbon dioxide emissions; the industrial structure effect of the third industry has regional differences, but on the whole, can curb carbon dioxide emissions. Therefore, it is necessary to reduce the proportion of the second industry, especially the proportion of high energy consumption industries, and increase the proportion of the low energy consumption industry and the third industry; but the industrial structure effect of Industry and construction industry led to the obvious increase in carbon dioxide emissions, so in order to reduce carbon dioxide emissions, it is necessary to reduce the proportion of the second industry, especially the proportion of high energy consumption industries; economic growth is the main source of carbon dioxide emissions, population growth has a certain extent in resulting in the increase of carbon dioxide emissions, energy intensity can effectively suppress the increase in carbon dioxide emissions, energy structure has relatively a small impact on carbon dioxide emissions; the relationship between carbon dioxide emissions and GDP per capita has regional differences, but all areas are facing with such a situation Carbon dioxide emissions increased with the increase of per capita GDP.
