Research on the Impact of Digital Economy on Innovation Performance of R&D Investment
Digital economy is a necessary basis for scientific and technological innovation,industrial upgrading,quality improvement and efficiency improvement and core competitiveness reconstruction in various countries.It is of great significance to study the development level of regional digital economy and its impact on the innovation performance of R&D investment in China.Firstly,this paper calculates the regional digital economy development level based on entropy method and the regional R&D investment innovation performance based on Super-SBM method.Then,multiple empirical analysis methods such as static panel model,dynamic panel model and dynamic spatial Durbin model are used to analyze the impact of regional digital economy development level on innovation performance.The empirical analysis results show that regional digital economy has a positive impact on the innovation performance of R&D investment,and the regions with high development level of digital economy and innovation performance of R&D investment are mainly concentrated in the Beijing-Tianjin-Hebei region,the Yangtze River Delta and the Pearl River Delta.The research results provide a basis for further formulating policy recommendations on the development of digital economy to promote science and technology innovation.
