The Mechanism of Digital Infrastructure Driving Regional Innovation:Empirical Study Based on Panel Data from Chinese Provinces
Evaluate the innovative driving force of digital infrastructure,analyze the role,degree,and conditions of digital infrastructure in regional innovation,and explore the relationship between infrastructure transformation and innovation model evolution from the perspective of new structural economics.Using panel data from 30 provinces in China for empirical research,it is found that:digital infrastructure investment significantly promotes the improvement of regional innovation,and is achieved through channels including independent R&D,technology introduction,knowledge supply and innovation transformation,the innovation effect of digital infrastructure investment on the eastern region is greater than the central region,and the effect on the central region is greater than on the western region;the effect on the basic research is greater than the applied research,and the effect on high-quality innovation is greater than on low-quality innovation;meanwhile,with the improvement of factor endowment,marketization and intellectual property protection,the promotion of digital infrastructure on regional innovation is increasing;furthermore,digital infrastructure investment can promote the transformation of innovation model from introduction and imitation to independent research and development.Based on this,further stimulating the role of digital infrastructure in driving innovation requires strengthening supporting construction and implementing policies tailored to local conditions and structures.
