摘要
采用2010—2020年我国31个省级行政区(不含港澳台)的面板数据,运用双向固定效应模型,实证分析数字经济对科技创新的影响。结果表明:第一,数字经济能显著促进区域科技创新水平提升,通过一系列稳健性检验以及考虑可能存在的内生性问题后,结果依然稳健。第二,财政压力是影响科技创新的重要因素,财政压力越小的地区,数字经济对区域科技创新的促进作用越明显。第三,数字经济对区域科技创新的影响具有非线性特征。第四,2013年“宽带中国”战略实施后,数字经济对于区域科技创新的提升作用更为明显。因此,应进一步提升数字经济发展水平,加快数字基础设施建设,营造良好的政策环境;合理控制地方财政压力,充分释放数字经济为科技创新带来的红利。
Using the Panel data of 31 provinces in China(excluding Hong Kong,Maco and Taiwan)from 2010 to 2020,this paper empirically analyzes the impact of digital economy on scientific and technological innovation using the two-way fixed effect model.The results indicate that:Firstly,the digital economy significantly promotes the improvement of regional scientific and technological innovation.After a series of robustness tests and considering potential endogeneity issues,the results remain robust.Secondly,fiscal pressure is an important constraint factor affecting technological innovation.The smaller the fiscal pressure,the more obvious the promoting effect of the digital economy on regional technological innovation.Thirdly,the impact of the digital economy on regional technological innovation has non-linear characteristics.Fourthly,after the implementation of the“Broadband China”strategy in 2013,the role of the digital economy in enhancing regional technological innovation has become more apparent.Therefore,it is necessary to further enhance the development level of the digital economy,accelerate the construction of digital infrastructure,create a good policy environment,and reasonably control local financial pressure,fully unleashing the dividends brought by the digital economy for technological innovation.
