利用创新技术效率和创新转化效率全面衡量创新效率，创新技术效率反映创新资源投入到创新成果的效率，创新转化效率反映创新成果到经济产出的效率。以1999-2008年中国省际区域为研究对象，分别运用产出法和投入法构建随机前沿模型，考察创新技术效率和转化效率的差异，以及各自的影响因素。研究发现，中国各区域存在显著的创新生产过程的无效率和创新转化过程的无效率。创新的技术效率和转化效率之间存在较大差异，转化效率明显低于技术效率，表现出“创新转化效率不足”导致的“创新生产能力相对过剩”的独特现象。加快提高创新成果转化的效率已是各地创新发展战略的关键。另外，创新技术效率和转化效率呈现出显著的东、中、西部地区间差异。%T he innovative technical efficiency and innovative conversion efficiency are applied to overall measure innovation efficiency .Innovative technical efficiency reflects the efficiency of innovation resources inputted in innovation achievements .Innovative conversion efficiency reflects the efficiency of innovation a-chievements becoming economic output .T his paper regards provincial regions in China during 1999-2008 as the objects of study and applies output method and input method to construct stochastic frontier model which is used to investigate the differences between innovative technical efficiency and innovative conver-sion efficiency as well as their respective influence factors .The researches find that there exists remarkable inefficiency in innovation production process and inefficiency in innovation conversion process .There are large differences between innovative technical efficiency and conversion efficiency .Conversion efficiency is significantly lower than technical efficiency .Insufficient innovative conversion efficiency leads to relative surplus of innovation production capacity .Accelerating improvement of innovation achievement conversion efficiency is the key to innovate for development strategies in each region .In addition ,innovative technical efficiency and conversion efficiency present obvious regional differences in the east ,middle and west of China .
