China is facing a huge energy consumption growth in its rapid industrialization and urbanization process.So it is important to identify energy consumption links for good policy-making.The paper uses input-output table to decompose the energy consumption growth in China from 1990 to 2002.The energy consumption growth is decomposed into three parts:technological effect,intermediate demand effect and final demand effect.The result indicates that the technological effect is the key factor for energy consumption decrease,and it is more obvious in 1997-2002 than in 1990-1995.The differences of the technological advancement on the aspect of energy consumption among industries are obviously reflected in the intermediate demand effect.The intermediate demand effect is negative correlated with technological effect.So it seems necessary to put technological advancement into effect in every industry,especially industries which are sensitive to the adjustment of intermediate demand.Industries that consume much energy or increase demand quickly should strengthen technological advancement.Final demand effect has close relationship with international trade structure,so it is necessary to consider value added and energy consumption per product simultaneously.
