技术创新投入对创新绩效具有直接影响。本文运用Pearson相关分析、改进的Griliches—Jaffe知识生产函数模型和逐步回归分析等方法,实证分析1995—2008年我国高技术产业技术创新投入对创新绩效的影响机理,并首次对高技术产业整体及其下属5个典型行业进行比较分析。结果表明:高技术产业整体与其下属行业之间、以及下属各行业彼此之间,其技术创新投入对创新绩效影响的效果存在明显差异;即使相同的投入要素在不同行业对初始创新绩效和最终创新绩效的影响效果也有显著差别;R&D投入和非R&D投入对创新绩效都有重要影响;对于不同行业创新资源的高投入并不一定都能带来高产出。在进一步分析这些差异及其原因的基础上,就今后我国高技术产业的协调发展战略提出了相关政策建议。
The relationships between Technological Innovation Input (TII) and innovation performance are explored with the panel data collected from Chinese high -tech industries during the period of 1995 -2008, the Pearson's correlation analysis, modi- fied function model of Griliehes - Jaffe knowledge production, and multiple stepwise regression analysis method are used as the a- nalysis methodology. The relationships among the entire high - teeh industry and its subordinate five typical industries are compared and analyzed. The results indicate that firstly, there are different relationships between the entire high -teeh industry and subordinate industries as well as among subordinate industries; secondly, even with the same factor of TII, there are different effects on initial and final innovation performance in different subordinate industry; thirdly, both R&D input and non R&D input have a positive impact on innovation performance, and the high input is not always brings high performance in different industries. Finally, some policy suggestions and managerial implications are provided on how to improve the innovation performance of Chinese high -tech industry.
