Based on the Laspeyres index and decomposition model,change taken place in energy consumption intensity in China from 1980 to 2003 has been analyzed in this paper.During this period,China's energy efficiency has been greatly increased;however,much more can be done to reduce the energy consumption in terms of the great gap between China and other developed countries on this issue.The decrease of China's energy consumption intensity from 1980 to 2003 was mainly due to the improved energy efficiency of industries as a whole.Compared to efficiency,industry structure has much less influence on the energy consumption intensity,furthermore,with the exception of few years,industry restructure even has a negative effect on energy efficiency.
