摘　　要：探索信息技术投资对不同阶段创新效率的影响机制及空间效应,对于实现信息技术的经济价值和提升区域创新效率具有重要现实意义。将区域创新过程分为技术研发阶段和市场转化阶段,基于面板随机前沿分析方法,测算中国2012-2020年两阶段区域创新效率,实证检验空间效应视角下信息技术投资对区域两阶段创新效率的影响,以及信息技术产业规模的调节作用。结果表明:在技术研发阶段区域创新效率呈逐年递增趋势,在市场转化阶段表现出先降后升的U型态势;两阶段创新效率存在显著的正向空间相关性;信息技术投资与技术研发阶段的创新效率呈正U型关系,与市场转化阶段的创新效率呈倒U型关系;信息技术产业规模分别负向和正向调节技术研发阶段、市场转化阶段信息技术投资对区域创新效率的影响。因此,应提高技术研发阶段的创新质量,重视基础研究并努力扩大信息技术产业规模,避免产业趋同与资源浪费。The issues of resource endowment,low input-output efficiency and uneven spatial distribution of resources are restricting the implementation of China's regional innovation development strategy,resulting in obvious spatial agglomeration characteristics and huge regional differences in China's innovation efficiency.It has become the key to achieving innovation-driven development by improving innovation efficiency and the quantity and quality of innovation output on the basis of limited innovation resource input.To solve the various contradictions in the current economic development and make technical breakthroughs in the high-tech field,it is necessary to further improve the level of national innovation as a driving force.Because of the differences in innovation resource allocation,innovation environment and industrial base,the innovation process and innovation efficiency of different innovation stages should be treated specifically.As an important means to create and cultivate new economic momentum and new economic growth points,information technology has become a key support point for innovation-driven high-quality economic development,and is significant for optimizing regional resource allocation and industrial structure adjustment.Information technology not only provides high-quality R&D personnel,accelerates organizational learning and knowledge flow and reduces organizational costs of technology R&D,but also promotes the quality and efficiency of traditional industries through penetration and substitution effects,deriving various emerging economies and digital platforms,thereby improving regional productivity and achieving innovation-driven development.In addition,there is a close geospatial relationship between regional innovation systems and their innovation elements,and it is necessary to include spatial econometric models in the research process to examine the innovation effect of information technology investment and the phenomenon of spatial agglomeration.According to the innovation value chain theory a
