| 摘 要： | 本文使用DEA方法和技术创新的两阶段模型来测度我国LMT产业技术创新活动的相对效率并分析影响我国LMT产业创新绩效提高的关键因素。研究结果表明: (1) 我国中技术产业的创新效率最低，而低技术产业却拥有比高技术产业更高的创新效率; (2) 提高将技术成果转化为经济收益的效率是我国LMT产业创新发展的关键问题；（3）我国LMT产业在创新活动的各阶段主要表现为显著的规模报酬递增，因此加大LMT产业的创新投入更有经济价值。

| Abstract: | This paper intends to measure relative efficiency of technological innovation in Chinese Low-and Medium-Technology(LMT) sectors and research the clues to improve it.The Data Envelopment Analysis(DEA) technique and the technological innovation two-stage model are applied for this purpose.The results indicate that:(1) In China,the medium-technology sectors have lowest innovation efficiency,but the low-technology sectors achieve the highest innovation efficiency,even compared to the high-technology sectors;(2) The kernel of LMT sectors development is to enhance the transforming efficiency from technical outputs into economic income;(3) At all stages of innovation,Chinese LMT sectors mostly show increasing returns to scale,so it is very necessary to increase the innovation input in Chinese LMT sectors. |
