不同经济发展水平下创新要素对产业创新绩效的影响及政策启示

基于不同经济发展水平研究视角，选取新一代信息技术产业为研究对象，采用改进的Griliches-Jaffe知识生产函数模型，运用面板数据回归分析方法，利用《中国高技术产业统计年鉴》（2007-2017年）中电子及通信设备制造业统计数据进行实证研究，探究创新要素投入与创新绩效的关系。结果发现：对于新一代信息技术产业，在不同经济发展水平地区投入相同创新要素对创新绩效的影响存在一定差异，尤其体现在技术投入要素作用效果上。这就意味着，对经济发展水平不同地区使用相同的创新要素推动产业创新发展是低效的；不同发展水平地区有针对性地分配创新要素，对于实现创新要素最大效率、推动战略性新兴产业布局与发展尤其关键。最后，提出相应政策启示及建议。

The Impact of Innovation Elements on Innovation Performance under Different Levels of Economic Growth and the Policy Implications

In this study, the new-generation information technology industry was selected as the subject.From the perspective of different levels of economic growth, the improved Griliches-Jaffe knowledge production function model was adopted.The panel data regression analysis method was used, and an empirical study was conducted based on the statistical data of electronic and communication equipment manufacturing industry in China Statistics Yearbook on High Technology Industry (2007-2017) to explore the relationship between innovation elements input and innovation performance.The results showed that for the new-generation information technology industry, there were differences in the impact of the same innovation elements on innovation performance in regions with different levels of economic growth especially in the effect of technology input factors, suggesting that it is inefficient to use the same innovation element to promote industrial innovation development in regions with different levels of economic development.Targeted distribution of innovation elements in regions with different levels of economic growth is particularly critical to achieve the maximum efficiency of innovation elements and promote the layout and development of strategic emerging industries.The corresponding policy implications and suggestions were also provided in this paper.
