数字经济对区域创新绩效影响的实证研究--以安徽省为例

An Empirical Study on the Impact of Digital Economy onRegional Innovation Performance--Take Anhui Province as an Example

数字经济正逐渐成为区域创新发展的重要驱动力,研究其对区域创新绩效的影响具有重要意义。文章通过构建2011-2019年安徽省各地级市的面板计量模型,探讨数字经济对区域创新绩效的影响与机制。研究表明:(1)基准回归中,数字经济的发展对区域创新绩效具有显著提升作用,数字经济每提高1%,区域创新绩效增长0.807%;(2)机制分析中,数字经济能够以人力资本和研发投入为中介,间接地推动区域创新绩效的提升;数字经济对区域创新绩效的提升存在非线性特征;(3)空间溢出分析中:数字经济与区域创新绩效存在显著的空间相关性,对区域创新绩效具有正向溢出效应。结论:各地区应持续推进数字经济发展,提升创新发展水平,实现区域“联动”。

Digital economy is gradually becoming an important driving force for regional innovation development.It is of great significance to study its impact on regional innovation performance.A panel econometric model was constructed for the cities in Anhui Province from 2011 to 2019 to explore the influence and mechanism of digital economy on regional innovation performance.The results showed that:(1)In the benchmark regression,the development of digital economy had a significant role in improving regional innovation performance.For every 1%increase in digital economy,regional innovation performance increases by 0.807%.(2)In the mechanism analysis,the digital economy could indirectly promote the regional innovation performance through human capital and R&D investment,and the improvement by the digital economy had nonlinear characteristics.(3)In the spatial spillover analysis,there was a significant spatial correlation between digital economy and regional innovation performance,which had a positive spillover effect on the regional innovation performance.Therefore,it is concluded that all the regions should continue to promote the development of digital economy,improve the level of innovative development,and realize regional“linkage”.
