【摘要】 为促进区域创新空间结构优化与协调发展,基于2007—2018年我国30个省份有关创新数据,构建综合考虑互联网普及和知识溢出的知识生产函数,测度区域创新空间演进特征,并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:30个省份的创新空间存在极大的非平衡性,区域差异以2012年为分界线呈现先增加后减少的倒"U"型趋势。其中:互联网普及对本地区创新产出具有显著的抑制作用;知识存量溢出对区域创新产出具有显著的正向作用,而知识质量溢出呈现相反的结果;互联网普及放大了知识溢出对区域创新产出水平的影响。研究结论对重塑我国区域创新组织形态可行路径,在互联网普及政策制定、加大知识溢出效应和充分发挥互联网与知识溢出协同等方面提供政策启示。更多还原

【Abstract】 In order to promote the spatial structure of regional innovation and coordinated development, based on the relevant innovation data of 30 provinces in China from 2007 to 2018, this paper builds a knowledge production function considering the Internet popularization and knowledge spillover and measures evolution characteristics of regional innovation space, and uses spatial Dubin model to empirically analyze the effects of regional innovation space evolution caused by the Internet popularization and knowledge spillover. The results show that there is a great imbalance in the innovation space of 30 provinces, the regional differences shows an inverted U-shaped trend of first increasing and then decreasing with 2012 as the dividing line. Among them, the popularization of Internet has a significant inhibiting effect on regional innovation output, knowledge stock spillover has a significant positive effect on regional innovation output, while knowledge quality spillover has the opposite effect. Besides, the popularization of Internet amplifies the influence of knowledge spillover on regional innovation output. The research results provide a feasible path for reshaping China’s regional innovation organization form, and provide policy implications for Internet popularization policy formulation, enhancing knowledge spillover effect and giving full play to the synergy between Internet and knowledge spillover.更多还原
