Abstract: The changes in power consumption per unit GDP is the decisive factor in causing power consumption to deviate from economic growth. This article segments national economy into 43 specific industries, and uses the logarithmic mean Divisia index (LMDI) to decompose the structure and intensity effects on changes in power consumption intensity from 2006 to 2009. The results show that: (1) in overall perspective, the structure effect on changes in power consumption intensity weighs less than 30%, while the intensity effect plays a leading role, accounting for more than 70%. (2) The absolute values of structure effects across years are all negative, namely industry structure changes play a positive part on the decline of electricity consumption per unit GDP. (3) Segmenting industries to high energy-consuming ones such as: electric power, steel, chemical, nonferrous metal and building materials, the changes in consumption intensity and of the proportion of output value played a dominant role on the change of power consumption per unit GDP. Accurate decomposition analysis not only unravels the mysteries of China’s power consumption, it also gives important inspirations to policies: the adjustment of industrial structure is a slow gradual process. In the short term, the dominant factors causing energy intensity to decline is the declination of self-consumption intensity in segmented industries. The current focus and main potential in energy saving and emission reduction is to improve the energy consumption efficiency in segmented industries.
