| 摘 要： | 将R&D投入分为资本投入和人员投入，构建资本投入指数和技术创新绩效指数，利用门限回归模型检验资本投入和人员投入对技术创新绩效的影响。以中国专利密集型产业2006-2015年数据为样本进行实证分析，结果表明：资本投入、人员投入和研发机构数量对技术创新绩效均具有促进作用，技术获取及改造呈显著抑制作用。资本投入存在单一门限，对技术创新绩效的影响先促进后抑制，人员投入存在双重门限，对技术创新绩效的促进作用先降后升。样本产业普遍过度重视资本投入，投入数量超过门限值，人员投入利用效率较高。

Impact of R&D investment on technological innovation performance |
| |
| Abstract: | the R&D investment was decomposed into human capital investment and capital investment, capital investment index and technological innovation performance index were built. The panel threshold regression model was used to explore the impact of human capital investment and capital investment on technological innovation performance. It did an empirical research based on the panel data of China's patent intensive industries from 2006 to 2015. The result shows that the capital investment and human capital investment can promote the technological innovation performance, but the technology acquisition and renovation investment has the inhibition effect. There is a single threshold effect of capital investment on the technological innovation performance, the effect first promote and then inhibit. There is significant two-threshold effect of human capital investment on technological innovation performance, and the promotion effect first decrease and then increase. China's patent intensive industries generally pay too much attention to capital investment, and capital investment exceeds the threshold value, but human capital investment shows a high utilization efficiency. |
