采用技术相似度测算研发溢出效应,基于面板平滑转换模型,对技术差距变动下高技术产业中研发等驱动技术进步的路径、方向和程度进行了研究。结论认为,在技术差距的影响下,研发对技术进步率呈现非对称的正向影响,但研发投入结构失衡矛盾凸显等因素导致研发有效性程度不断下降。随着技术差距的变动,人力资本通过“协同效应”、“学习效应”对技术进步率具有差异化的促进作用。虽然缩小技术差距能够对技术进步率产生积极影响,但是高技术产业中研发活动的高度集聚现象,不利于溢出效应的发挥,降低了技术进步速度。最后,经济发展水平对于技术进步率的提升效应显著。技术差距为技术进步提供了增长空间,各地区应选取适宜的高技术进行引进,推动不同地区间高技术产业的协同创新,实现创新驱动技术进步和产出增长。
Based on the panel smooth transition model, the paper researches the path, direction and degree of the driving technology progress such as R & D in high-tech industry under the technology gap. The conclusion is that under the influence of technological disparity, research and development have an asymmetric positive impact on the rate of technological progress, but the imbalanced imbalances between research and development investment structure and other factors have led to declining effectiveness of research and development. With the change of technological gap, human capital through the “synergies”, “learning effect” has a differentiated role in promoting technological progress. Although narrowing the technological gap can have a positive impact on the rate of technological progress, the high concentration of research and development activities in high-tech industries is not conducive to the spillover effect and reduces the rate of technological progress. Finally, the level of economic development has a significant effect on improving the rate of technological progress. Technological gaps provide room for technological progress. All regions should adopt suitable high-tech technologies for introduction and promote coordinated innovation of high-tech industries in different regions so as to achieve innovation-driven technological progress and output growth.
