The traditional policies and measures to improve energy efficiency are challenged severely since the existence of rebound effect and the calculation is the focus.  The effect of technical progress was quantified based on logarithmic mean Divisia index (LMDI).  The improved model of the rebound effect of energy resource was constructed.  It is concluded from the empirical research are: the influence from technical progress to energy efficiency is a dynamic process; rebound effect fluctuates in different periods and it shows the descending trend.
