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

摘要： 讨论了数字经济对区域高技术企业创新绩效的影响，及区域高校知识转移对其路径的作用机制。基于2011~2018年中国省级面板数据测度区域数字经济发展指数，并在此基础上进行多维度计量分析检验。结果显示：数字经济显著促进了高技术企业创新绩效，这一结论在选取邮电历史数据作为工具变量等进行稳健性检验后依然成立。高校知识转移与数字经济形成正向的交互驱动效应。在高校知识转移的作用下，数字经济对高技术企业创新绩效呈现“U”型影响。由空间模型发现，数字经济对于高技术企业创新绩效呈现出负向的空间溢出特点。区域与企业异质性分析结果显示，自然区位与企业规模、所有权结构以及注册类型下的数字经济对于高技术企业创新绩效的影响存在差异。研究结果为高技术企业优化校企合作技术转移策略，探索有效的高技术企业创新驱动路径提供了有益参考，也为政府部门积极谋划数字经济发展战略布局提供了有益的借鉴。
