Measurement Of Embodied Air Pollutant And Influential Factors Decomposition In China's Export Trade

With the rapid development of trade and the increase of energy consumption,the relationship between China's export trade and environment is becoming more and more serious.In terms of climate change,the expansion of international trade will not only affect the effect of greenhouse gas emission reduction worldwide,but also further aggravate China's air pollution problem.China's sulfur dioxide,nitrogen oxide and smoke and dust(powder)emissions is high in the world,air pollution is serious,smog frequent phenomenon,serious impact on people's production and living,the call for the public to reduce air pollutant emissions is more and more strong.Based on environmental input-output analysis and factor decomposition analysis,using the list of Chinese source pollutants emission from bottom to top,this study calculated the implied in the 2002,2007 and 2012,China's export trade of sulfur dioxide,nitrogen oxide and smoke and dust(powder)emissions.Results show that,with the progress of producing technology in China's export products,the emission coefficient is reducing,the overall level of embodied air pollutants emission coefficient in 2012 is lower than 2007,the overall level in 2007 is lower than2002.But through technology advances drive to reduce emmision coefficient with only short-term effect,the potential of emission coefficient reducing in gradually decreases,the results showed that from 2007 to 2012 the influence of the energy intensity effect on total effect is significantly lower than the 2002-2007.Emissions of sulfur dioxide and implied nitrogen oxides rose slightly in 2012 compared with 2002,while the emission of implied smoke(powder)fell by 53.49% from 2002 to 2012.On three kinds of air pollutant factors LMDI decomposition implied found that,overall,the main driving factors of embodied air pollutant emissions in China are the export scale effect,followed by export dependence effect and export structure effect;The main restraining factors are energy intensity effect and emission factor effect.By department decomposition shows that,China's export products of air pollutant emission sources are mainly concentrated in large energy consumption,low efficiency industries,mainly from chemical products,non-metallic mineral products,etc.Energy intensity effect and emission coefficient effect make the emission reduction effect of wood processing and furniture manufacturing industry.The export scale,export structure and export dependence effect greatly reduce the emission of air pollutants in heavy industries such as chemical industry.In view of the above analysis,policySuggestions are put forward from energy utilization efficiency,export structure and industrial level,so as to provide reference for the coordinated development of China's trade and environment.
