不同高技术产业创新路径绩效比较研究——基于系统广义矩与分位数回归模型的估计

A Comparative Study of the Performance of the Different Channels of China's High-tech Industry Innovation——Based on the Assessment by Sys-GMM and Quantile Regression Models

绩效是创新路径选择的重要依据,利用高技术产业省际面板数据,采用系统广义矩估计与分位数回归方法,研究企业自主研发、引进国外技术、引进国内技术、更新改造四种不同途径科技投入对创新产出的贡献。结果表明:企业自主研发投入贡献最大,引进国外技术投入次之,更新改造投入贡献最小。高技术企业自主研发投入与引进国外技术的结合较好。引进国内技术投入对最高科研产出水平地区的贡献比较显著,研发人员全时当量的贡献总体较低,并且随着科技产出的提高,其贡献越来越低,说明高科研产出地区研发人员的绩效较低。

Performance is an important gauge of the channels of innovation. Based on panel data of provincial high-tech industry, this paper analyzes the contributions of four channels of scientific and technological input to innovation output, namely, enterprises＇ self R＆D input, the import of foreign technology, the introduction of domestic technologies and equipment upgrading and transformation by using Sys-GMM and Quantile Regression Models. The results show enterprises＇ self R＆D input yields highest contribution, the import of foreign technology ranks the second, while equipment upgrading and transformation ranks the last. The combination of self R＆D input with foreign technology importing yields better results in those enterprises with high technologies. The introduction of domestic technologies makes significant contribution in those areas with the highest level of scientific and technological output while the overall contribution of R＆D staff is comparatively low and turns out to be worse with the increase of scientific and performance of R＆ D staff in those areas with high level of technological output, indicating comparatively poor scientific and technological output.
