互联网具有的“时空压缩”效应可充分释放知识溢出效应，成为优化资源空间配置和提高区域创新水平的重要途径。基于2007-2018年中国省域创新数据，对区域创新空间演进特征进行测度，并构建了综合考虑互联网普及和知识溢出的知识生产函数，运用空间杜宾模型实证分析互联网普及与知识溢出对区域创新空间演进的影响。结果表明：我国省域创新空间存在极大的非平衡性，省域间差异以2012年为分界线呈现先增加后减少的倒“U”型趋势。具体包括：①互联网普及对本地区区域创新产出具有显著的抑制作用；②知识存量溢出对区域创新产出具有显著的正向作用，知识质量溢出呈现相反的结果；③互联网普及放大了知识溢出对区域创新产出水平的影响。本研究结果有助于认识重塑区域创新组织形态的可行路径，对实现我国区域创新空间结构优化与协调发展具有重要的现实意义。

The "spatiotemporal compression effect" of the Internet has fully unlocked the knowledge resources of space and become an important breach of knowledge spillover and regional innovation. Based on the provincial innovation data of China from 2007 to 2018, this paper measures the evolution characteristics of regional innovation space, constructs a knowledge production function that comprehensively considers Internet popularization and knowledge spillover, and empirically analyzes the impact of Internet popularization and knowledge spillover on the evolution of regional innovation space using the spatial Dubin model. The results show that there is a great imbalance in the innovation space among provinces in China, and the differences between provinces show an inverted "U" pattern with 2012 as the dividing line, including that ①The popularization of the Internet has a significant inhibitory effect on regional innovation output in this region; ②The knowledge stock spillover has a significant positive effect on regional innovation output, while the knowledge quality spillover presents an opposite effect; ③The popularization of the Internet amplifies the impact of knowledge spillover on regional innovation output level. The results of this study are helpful to fully understand the feasible path of spatial evolution of regional innovation and have important practical significance to realize coordinated development.
