摘要
在创新型国家建设背景下,提高创新质量至关重要。以高技术产业为例,综合采用联立方程模型、面板门槛模型、贝叶斯向量自回归模型,研究技术积累与创新数量、创新质量的关系。研究结果表明:技术积累对创新数量的贡献大于创新质量;创新数量与创新质量间的协调性不高;技术积累对创新数量的贡献中其自身、研发人员、创新质量的门槛效应呈递减趋势;随着创新数量增大,技术积累对创新数量的作用弹性逐步提高;当研发经费处于中等水平时技术积累对创新数量的弹性影响最大,对创新质量具有较强的规模经济效应。
China’s economic development is shifting from quantity expansion to quality improvement, and innovation quality are receiving increasing attention. Technology accumulation is the foundation of enterprise innovation, and enterprise innovation is an important embodiment of technology accumulation level. Existing studies pay little attention to the relationship between technology accumulation and innovation quantity, and there are just a few studies on the relationship between technology accumulation and innovation quality. Moreover, there is no in-depth study from the perspective of innovation quantity and innovation quality, leaving the following questions untapped: the effect mechanism of technology accumulation on innovation quantity and innovation quality, the linear relationship between technology accumulation and innovation quantity and innovation quality;the characteristics, rules and the existing problems of the effect of technology accumulation on the quantity and quality of innovation and so on. Research on related issues is not only conducive to promoting technological innovation mechanism and innovation quality theory, but also has important significance for strengthening technology accumulation, improving innovation quality and improving innovation efficiency of enterprises.Taking the high-tech industries as the research object, this paper studies the relationship between technology accumulation and innovation quantity and innovation quality from the macro-regional perspective. It divides technology accumulation into production technology accumulation and R&D technology accumulation, and analyzes the mechanism of technology accumulation on the innovation quantity and innovation quality. The effect of technology accumulation on innovation quantity can be divided into three aspects. the first is the mechanism of the effect of traditional technology accumulation on the innovation quantity, including the improvement effect and the extension effect. The improvement effect refers to the continuous improvem
