Decomposition Of Carbon Emission Reduction And Decrease Carbon Of Industry In China

With the accelerating process of industrialization,the rapid development of the national economy consumes lots of energy,which has led to the release of excess carbon dioxide,increasing the global average temperature;with all kinds of extreme weather cropping up frequently,human survival environment has been further threatened.In this context,at home and abroad,the stage of energy saving and emission reduction targets have been put forward,along with the appropriate administrative means and market means.China has proposed:per unit GDP carbon emissions will be reduced by 18%on the basis of the ones of 2015,and reach the peak as early as 2030,as it has promised.Under the tremendous pressure of reducing emissions,this paper researches China’s carbon emissions factors,allocation of emission reduction and industry characteristics,which will be related to the reachability of energy saving emission reduction targets,policy direction and economic,social and energy long-term sustainable development.Based on the literature review of researches relating carbon emissions and the main analyzing methods of them,this paper analyzes the present situation of Chinese energy consumption,economic growth and carbon emissions at the regional and national levels;the correlation between Chinese carbon emissions,population,energy consumption and GDP is measured by gray relational analysis.The results show that there is a largest correlation between coal consumption,oil consumption and carbon emissions.With the direction and value of each influencing factor being analyzed by the Logarithmic Mean Divisia Index(LMDI),the results show that the economic effect has a dominant effect on the carbon emission,and the population has been promoting the growth of carbon emission,while the intensity is not strong;carbon emission influences the reducing emissions,while the energy intensity plays a main role.It means,on one hand.China should pay more attention to improve energy structure when planning emissions reduction,the focus of which should be put on improving the energy structure.namely,the increasing of the proportion of clean energy.conforming to the fact that oil and gas reserves are not high in China.On the other hand,in the case of stable economic growth,capital should be invested in improving energy efficiency,so that carbon emissions by the process of energy exploitation and utilization can be reduced.Based on the emission reduction constraint of regions from the energy conservation and national emission reduction policies,the BCC model in Data Envelopment Analysis(DEA)is used to evaluate the efficiency of the original carbon emission distribution plan in 2020,the result of which indicates that the efficiency of the original DEA is only 0.7409.Therefore,the ZSG-DEA model which devotes invariable quantum is introduced to optimize the scheme through iterative computation,by which,the BCC and ZSG-DEA efficiency of 30 provinces and cities finally reach 1,namely,the efficient frontier.Based on the results of the optimization scheme,the whole country is divided into four areas in accordance with emission reduction pressure:the carbon intensity of A area can be increased compared to 2015,while D area,including the provinces and cities with the highest emissions reduction pressure,should reduce its carbon emission intensity by Imore than 40%.The establishment of emission reduction schemes provides clear emission reduction targets for the regions,in order to achieve this goal,carbon emissions trading and other market means of emission reduction need to be taken.In addition,this paper,calculating the national carbon emissions of different industries from 1990 and combining with the situation of seven carbon emissions trading pilot areas,selects nine key industries as a research object,with the analyses of the carbon emission characteristic of 16 provinces in 2014 as well as the economic regions.The study also measures the low-carbon development ability of nine key industries through low-carbon development elasticity coefficient from 2005 to 2014,selecting the emission reduction key regions which combined with carbon emissions proportion.The national carbon market’s opening could strive to adjust the key emission reduction areas to ideal condition and narrow the gap between the region’s emissions.In the end,it puts forward some political suggestions about emission reduction based on the research results and special national conditions nationally and regionally.
