【摘要】 在推进数字基础设施建设背景下，基于区域创新系统理论，选取2012—2022年我国30个省份平衡面板数据，构建随机效应面板Tobit模型，探究数字基础设施对区域创新效率的影响机制。研究发现：数字基础设施有助于提升区域创新效率。异质性分析表明，地区与知识产权保护程度不同，均会导致数字基础设施对区域创新效率的影响产生差异。机制研究显示，在数字基础设施正向影响区域创新效率的过程中，研发人员流动、研发资本流动与研发技术转移均发挥着正向机制作用，创新发展模式发挥正向调节效应。研究结论为我国提升创新效能提供了一定经验证据。更多还原

【Abstract】 In the context of promoting the construction of digital infrastructure,based on the theory of regional innovation system,use the balanced panel data of 30 provinces in China from 2012 to 2022 to construct a random-effects panel Tobit model to explore the impact and internal mechanism of digital infrastructure on regional innovation efficiency. The study finds that digital infrastructure contributes to regional innovation efficiency. Heterogeneity analysis indicates that both regional differences and varying levels of intellectual property protection lead to divergent impacts of digital infrastructure on regional innovation efficiency. The mechanism study shows that in the process of digital infrastructure positively affecting regional innovation efficiency,R&D personnel flow,R&D capital flow and R&D technology transfer all play a positive mediating effect,while the innovation development mode plays a positive moderating effect. This study provides empirical evidence for China’s government to optimize the layout of digital infrastructure,promote innovation development strategy,and enhance innovation efficiency.更多还原
