Abstract

As China’s energy intensity fluctuated in recent years it is necessary to examine whether this fluctuation happened at a regional level This paper establishes a decomposition model by using the structural decomposition analysis SDA method at a regional level Then this model is employed to empirically analyze the changes of Beijing’s energy intensity The conclusions are as follows during 2002–2010 except petroleum the energy intensity decreased and the changes were mostly attributed to the technology changes while the final use variation actually increased the energy intensity comparing different periods of 2002–2010 the decline rates of energy intensity for coal and hydropower were decreasing resulting from the production technology being more energyintensive than before the energy intensity changes of petroleum firstly increased substantially and then decreased moderatelySupported by Strategic Priority Research Program of the Chinese Academy of Sciences No XDA05150600 National Natural Science Foundation of China No 71273027 and No 70903066 and Beijing Planning Office of Philosophy and Social Science No 11JGC105
