The Influence Effect Of Air Pollutants Change In China And An International Comparative Analysis

In recent years, along with the advance of industrialization and urbanization in China, China’s air quality continues to deteriorate. Haze appeared with more and more high frequency, and more and more wide range. Urban area of Beijing, Tianjin, Hebei, Henan, Shandong and other areas in North China, Yangtze River Delta and other urban areas of the East China region and the Pearl River Delta in southern China have become the haze target area, haze has seriously affected the climate in these regions, local population’s health, social stability and harmony. PM2.5 fine particles are important cause of haze pollutants, and the source is very complex. Sulfur oxides (SOX), nitrogen oxide (NOX), volatile organic compounds (VOCs) are important precursor gaseous pollutants of PM2.5 fine particulate. Under the the supply-side background of the reform, in order to promote the transformation and upgrading of economic structure, low-carbon, green and sustainable ideas are needed in the implementation of the reform. Therefore, focusing on the ecological environment governance must be as the breakthrough point of the reform of the supply-side.We adopt input-output table data for two developing countries, China and India, and two developed countries, the United States and Japan, emissions data of ulfur oxides (SOx), nitrogen oxides (NOx), volatile organic compounds (VOCs) from the World Input-Output Database (WIOD) for 1995-2009, and the population data published by the world bank data in China, India, the United States, Japan. From the perspective of supply-side structures, Ghosh input-output model decomposes factors influencing air pollutants into population size, population affluence, allocation structures, economic structures, and emission intensity. Firstly, the trend of air pollutants emission in China is analyzed. Secondly, according to the structural decomposition results, the change of air pollutant emissions in China is analyzed from the aspect of the whole effect and the supply-side effect. Finally, from the overall effect level and the supply-side effects of the department level, the cross-border comparative analysis of China’s air pollutant emissions is made.Results show that:firstly, air pollutants in China showed a sharp rise after a slight fluctuation, after the accession to the WTO in 2001, China air pollutants have a sharp rise, the process of industrialization brought a substantial emissions of air pollutants. Secondly, population affluence effect is an important factor in prompting the air pollutants emissions, and emission intensity effect is an important factor inhibiting countries air pollutants emissions. The allocation structures effect promote to increase air pollutants in China, economic structures effect on China air pollutants are transferring from promoting to suppression. Compared with other countries, allocation structures promoted the China and Japan the air pollutants to increase, inhibited the air pollutants in India and the United States, the effect of economic structure promoted the air pollutants emissions, inhibited the air pollutants emissions of India, the United States. Thirdly, from industry analysis, in 1995-2009, the allocation structures effects promoted air pollutants are greater than inhibition in China and Japan, which lead allocation structures have negative impact on China and Japan air pollutants. The allocation structures effects inhibited air pollutants are greater than promotion in India and the United States, which resulting in allocation structures have positive impact on India and the United States air pollutants. Economic structure effects promoted air pollutants are greater than inhibition in China, which lead allocation structures have negative impacts on China air pollutants. Economic structure effects inhibited air pollutants are greater than promotion in India, the United States and Japan, which resulting in allocation structures have positive impacts on India, the United States and Japan air pollutantsIn the end, the paper puts forward the policy recommendations include:Optimize the industrial structure, and reduce the effects of supply-side structure on the promotion of air pollutants..
