Abstract:

Based on the research and analysis about the characteristics and the law of evolution of CO2 emission in the past 16 years (1995—2010) in China's eight regions, using the method of LMDI decomposition, the effects of China's CO2 emission was decomposed into four influencing effects, which were population size effect, economic development effects, energy intensity effect and energy structure effect, the reason why China's CO2 emission showing regional differences was found. The results show that: 1) the amount of carbon emissions and per capita carbon emissions of eight regions showed an upward trend in the past 16 years. 2) The proportion of carbon emissions in the regions of Northeast China, Beijing and Tianjin as well as the eastern coastal zone showed a declining trend, other regions were showing an opposite trending or remaining unchanged. 3) Economic development effects have the strongest positive impact on carbon emissions, energy intensity effect has the strongest negative effect on carbon emissions. And 4) population size effect has a greater positive impact on the growth of CO2 emission in regions including municipalities, economic development effects have a weaker positive impact on the growth of CO2 emission in developed regions than other regions, energy intensity effect has an inhibition impact to the regions having an active economic restructuring, energy structure effect was affected by macroeconomic and national energy policy, which has a big fluctuation impact on carbon emissions.

Key words: carbon emissions, LMDI, regional difference
