技术效率是经济增长源泉和增长质量的一个重要问题，而技术创新则是影响技术效率的根本因素，那么作为技术创新核心的R&D对技术效率是否存在着积极影响？本文运用面板数据随机前沿方法(SFA)考察了我国三大经济区域R&D与技术效率之间的内在关系，实证结果显示：①R&D对技术效率具有显著的正向促进作用；②随着R&D投入逐年递增，东、中、西部地区的平均技术效率水平呈稳定上升趋势；③随着时间推移，东、中、西部地区之间的技术效率差距呈继续扩大态势。在实证基础上，进一步分析了R&D对技术效率的作用机理和区域差异的路径依赖，并由此得出相关结论与政策建议。  

    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.
