Abstract:

Based on Kayaequation,the affecting factors of consumption of electric power were decomposed into economy growth,industry composition and intensity of electric power.And they were analyzed based on the time list decomposition way of LMDI method during 2000～2007.The outcomes of decomposed analysis show that economy growth,industry composition and intensity of electric power are all have some positive effect on the increase of consumption of electric power as a whole.And economy growth is the major factor causing the growth of consumption of electric power;its contribution attained 9365%.But since 2006,industry composition and intensity of electric power have been displaying some kind of electric power mitigation effect.During 2006～2007,74130 hundred million kWh had been reduced for the change of industry composition and 1 64370 hundred million kWh for the depress of intensity of electric power.Study results show that the consumption of electric power would increase if China′s economy keep developing,and adopting clean power,adjusting industry composition and reducing intensity of electric power are the main approach to make China′s consumption of electric power decrease
