Abstract: The technique efficiency is an important problem for the economy growth headspring and the growth quantity,and the technique innovation is prime factor that affects the technique efficiency。Has the R&D as the core of technique innovation positive influenced on the technique efficiency? Using Stochastic Frontier Approach(SFA) of pannel data, the intrinsic relation between the R&D and the technique efficiency of the east, central, west regions in China was investigated, the experiential result shows: ①The R&D has remarkable positive promoting function on the technique efficiency; ②With the R&D expenditures increasing year by year,the average technique efficiency level of the east, central, west regions present steady-up trend; ③With the lapse of time,the gap of the technique efficiency presents the extended situation beween the east and central, western regions.On the base of the experiential research, the mechanism and path dependence of R&D impact on the technique efficiency are analyzed, and the conclusions and policy suggestions according to this are put forward.
