Estimation of Technological Progress and Structural Readjustment on the Energy Consumption Rebound Effect

Our country's current energy consumption is faced with economic growth and reducing the energy intensity to meet the dual pressure,and it is urgent to improve the energy efficiency of energy imminent.So,improving the energy efficiency will save energy consumption? The paper analyzes the rebound effect of technological progress based on Chinese data from 1992-2011,the result shows that:energy efficiency that brought about by improving technological progress can save energy consumption,but the rebound effect of energy consumption exists significantly,the rebound effect of energy consumption ranged from 9% to 75%.On this basis,the paper extended the concept of rebound effect of energy efficiency,we think that rebound effect of energy efficiency should includes two parts:one is the rebound effect of technological progress,and the other is the rebound effect of structural readjustment.The reason is that the improved energy efficiency can be decomposed into two effects.One is the effect of technological progress,and the other is the effect of structure adjustment,so the rebound effect of energy efficiency can be decomposed into two effects,The rebound effect of energy efficiency means that technological progress and structural adjustment can improve energy efficiency,and can save energy consumption,but technological progress and structural adjustment will promote the rapid growth of economy,and then have a new demand on energy that partially offset the saving energy.Finally the calculated results based on Chinese data from 1992-2011 shows that the rebound effect of structural adjustment is much greater than the rebound effect of technology progress,energy efficiency brought about by improving technological progress also can save energy consumption,the rebound effect of energy consumption also exists significantly,improved energy efficiency brought about by structural readjustment plays a little important role in energy conservation,the rebound effect of structural adjustment in different years shows larger fluctuation,and the rebound effect of structural adjustment is at the two extremes in most of the years,which is greater than 100% or negative.
