The Empirical Research On The Differences Of Carbon Dioxide Emissions Among Beijing,Tianjin, Shanghai And Chongqing Based On LMDI

Energy is one of the key material bases during the development process of human society, butthe sharp increasing emission of carbon dioxide caused by consuming large amount of fossilenergy has resulted in a lot of problems to earth natural environment, including global warming,sea level rising, more natural disasters. Climate change and low-carbon development has becomethe focus in the international community, the low-carbon development mode in the future has beenagreed by nearly all the countries in the world. In such a setting, China has issued series ofpolicies and measures in order to promoting low-carbon development.This paper estimated the differences of carbon emissions among Beijing, Shanghai, Chongqingand Tianjin from1995to2008, based on10kinds of energy consumption data in39mainindustries and residents’ sector. And on the basis of expanded Kaya identical equation, we built theLMDI decomposition model of carbon emissions’ driving factors and decomposed the drivingfactors into7kinds, that is manufacturing energy intensity, residential energy intensity, energystructure, industry structure, product per capita, income per capita, and population scale. And then,this paper calculated every driving factors’ contributions to the growth of carbon emissions andtheir variation tendency. It revealed the main reasons of the differences of each municipalitydirectly under the Central Government, and proposed several policy suggestions on how toaccelerate low-carbon development.Through the above analysis, the main conclusions of this article show that: compared to Tianjincity, manufacturing energy intensity and product per capita effect CO2emission of Beijing innegative direction, income per capita and population scale effect CO2emission of Shanghai inpositive direction, industry structure, income per capita and product per capita effect CO2emissionof Chongqing in negative direction.
