数字经济对中国区域创新产出的影响

A Study on the Impact of Digital Economy on Regional Innovation in China

文章以全国面板数据为研究样本,从劳动生产率和地方公共财政支出视角探究数字经济对创新产出的影响以及创新投入的中介效应。研究发现,数字经济规模能显著促进创新投入,从而提高创新产出能力。劳动生产率调节了数字经济与创新投入之间的关系,各地区劳动生产率越高,数字经济对创新投入的促进作用就越强;地方公共财政支出调节了创新投入与创新产出之间的关系,地方公共财政支出占比越高,创新投入转化为创新产出的效率就越高。中西部地区数字经济对创新投入和创新产出的促进作用小于东部地区,但中西部地区的创新投入对创新产出的促进作用大于东部地区。研究结果为促进科技创新以及加快数字经济创新发展提供参考,并提出数字经济促进创新产出的政策建议。

Taking the national panel data as the research sample,this paper explores the impact of digital economy on innovation output and the intermediary effect of innovation input from the perspective of labor productivity and local public finance expenditure. The scale of digital economy can significantly promote innovation input,thus improving innovation output capacity. Labor productivity regulates the relationship between digital economy and innovation input. The faster labor productivity grows in each region,the stronger the digital economy promotes innovation investment. Local public finance expenditure regulates the relationship between innovation input and innovation output. If the proportion of local public finance expenditure is high,the efficiency of transforming innovation input into innovation output is higher. Although the promotion effect of digital economy on innovation input and innovation output in central and western regions is less than that in eastern regions,the promotion effect of innovation input on innovation output in central and western regions is greater than that in eastern regions. This paper provides practical reference for improving fiscal policy,promoting scientific and technological innovation and accelerating digital economy innovation. Finally,this paper puts forward some suggestions to promote innovation output through digital economy.
