Abstract: This paper discusses the impact of the digital economy on regional high-tech enterprise innovation performance, and the influencing mechanism of regional university knowledge transfer on the above path. Based on the provincial panel data of China from 2011 to 2018, it measures the regional digital economy development index, and conducts multidimensional econometric analysis. The results show that the digital economic development index significantly promotes high-tech enterprise innovation performance, which is still true after the robustness test of selecting the historical data of posts and telecommunications as the instrumental variable. University knowledge transfer and digital economy have a positive driving interaction effect. Under the influence of university knowledge transfer, digital economy has a U-shaped effect on high-tech enterprise innovation performance. Based on the spatial model, it is found that the digital economy has negative spatial spillover characteristics for high-tech enterprise innovation performance. The results of the region and enterprise heterogeneity analysis show that the impact of the digital economy on high-tech enterprise innovation performance is different under the natural location, enterprise scale, enterprise ownership structure, and enterprise registration type. The research results provide a useful reference for high-tech enterprises to optimize the technology transfer strategy of university-enterprise collaboration, and explore effective driving paths for high-tech enterprise innovation. They also provide a useful reference for government departments to actively plan the strategic layout of digital economy development.

Key words: digital economy, university knowledge transfer, enterprise innovation performance, knowledge dissemination
