In comprehensive consideration of the impact of economic growth and energy intensity on carbon emission, based on the related data of 30 provinces during 1997-2011 in China, by using the panel unit root, cointegration test methods and error correction model, this paper describes the change trend of the amount of carbon emission, total GDP, carbon emission intensity in the eastern, middle and western regions, and verifies that there is longterm cointegration relationship among economic growth, energy intensity and carbon emission in each region of China. 1% increase of economic scale causes 1.42% increase of carbon emissions. Judging from the results of shortterm error correction model, there is a dynamic adjustment mechanism among energy intensity, economic growth and carbon emissions.
