Abstract:

The paper discomposed the CO2 emissions during the period of 1990~2007 using logarithm mean Divisa method based on Chinese energy consuming and economic growth.The result indicates that economic growth effect is the main reason of the increase in CO2 emissions while energy intensity effect is the main factor to obstruct CO2 emissions.Study of different regions indicates that economic development and energy intensity effect of coastal region are stronger than that of inner land.Population effect increase CO2 emissions in coastal region while decrease the CO2 emissions in inner land.Structure effect can decrease the CO2 emissions in coastal region，but has little effect on central and western regions.Therefore，it is necessary to give different policies regarding the regional characteristics to reduce CO2 emissions.For costal region，technology levels should be promoted to raise the energy efficiency.For inner land areas，energy structure should be changed and clean energy should be introduced in order to decrease the proportion of coal，on the other hand，industrial structure should be transformed，service and low energy consuming manufactures should be encouraged.

Key words: economic growth/ energy intensity/ CO₂ emissions/ CO₂
