Study on China's Energy Consumption Intensity and the Potential of Energy Saving

Index-factor analysis is employed to divide the change of energy consumption intensity into structure share and efficiency share,and the impact of industrial restructuring and change in industrial energy efficiency on China's energy consumption intensity and energy saving is analyzed.The result shows that,after 1990,the decline of the energy consumption intensity is mainly affected by the changes in internal structure and efficiency of the industrial sector,and the efficiency share of energy consumption intensity is a crucial factor.For the influence to different industries,the structure share and efficiency share of industry are exceed other industries;it is the crucial industry of affecting energy consumption intensity.The energy saving come from efficiency saving.Therefore,the technology,market and administrative measures should be used to improve industrial energy efficiency in the short term,especially the heavy chemical industry's energy efficiency,and this could achieve energy saving goal to a certain extent.
