Research On The Influence Factors Of China’s CO₂ Emissions On The Reginal Differences

With the development of economy,the total amount of carbon emissions is increasing,and the relationship between carbon emissions and climate is changed.At the same time the damage caused by greenhouse effect is worse than before.China,as the world’s second largest economy,has a large population with fast economic development speed,but has become the largest carbon emissions country in the world.As a responsible country,the emission reduction policy is of great urgency.It is a major challenge for China that how to find a low-carbon economy and accelerate the transformation of economic development model to achieve sustainable economic development at this stage.China has vast territory,population,technology and economic development level and characteristics of the obvious regional differences.Based on the STIRPAT model,this paper introduces the influence factors of geographic location on the basis of summarizing relevant literatures home and abroad,and deeply analyzes the impact of population,economy,technology and energy intensity on carbon emissions in different regions of China.Targeted reduction measures put forward the relevant.This paper first uses the Theil index method to measure carbon intensity and carbon emission per capita as an indicator of carbon emissions.The regional differences of carbon emissions from 2000 to 2014 are decomposed into three national parts and eight regions.The results show that at the national level,the Theil index of carbon intensity is smaller than that of per capita carbon emission,indicating that the matching degree of carbon dioxide emission and gross domestic product(GDP)is higher than that of carbon dioxide emission and population.The Theil index of regional carbon intensity is larger than that of inter-regional Theil index,while the average Theil index of per capita carbon emission in the region is smaller than that of regional per capita carbon emission index.At the eight regional levels,Or the Theil index of per capita carbon emission,and the regional differences are obviously different from those in the central region and the developed regions.Therefore,it is not difficult to find out that the proposed regional policy is more effective because of the large geographical area of China,and the traditional three-regional division can not fully reveal the regional differences.Secondly,based on the premise of regional differences,this paper uses the STIRPAT model to analyze the factors that affect the regional carbon dioxide emissions.The results show that,at the national level,population factors and economic growth,urbanization rate,population size,per capita GDP and energy structure have a great impact on carbon intensity and carbon emission per capita.At the three regional levels,the energy intensity plays the most important impact on carbon emissions.In terms of carbon intensity,the eastern was affected by the industrial structure and urbanization obviously,while the population size and urbanization play a more important role in the Midwest.Besides in terms of per capita carbon emissions,the per capita GDP,urbanization and population size influence on the East Midlands obviously.The urbanization and industrial structure play a major role in promoting carbon emissions in the west.At the eight regional levels,from the carbon intensity of view,energy intensity,population size,per capita GDP,industrial structure and urbanization have significant effects on promoting carbon emissions,chief of all is energy intensity.From the per capita carbon emissions,population size,per capita GDP and energy intensity are chief effects,the next are industry structure and urbanization.Finally,according to the results of empirical research in different regions,this paper puts forward some suggestions on carbon emission control.
