文章基于2006-2020年的中国发明专利授权数据,以地级及以上城市作为研究单元,对比全部创新活动,探讨了中国的数字经济创新活动时空格局特征,并从知识生产函数视角构建空间面板数据引入空间杜宾模型揭示了其驱动机制.研究发现:①中国数字经济创新日益成为创新活动中的重要领域,并呈现显著的空间不平衡特征,空间集中度相对全部创新活动更高;②数字经济创新水平与城市创新能力存在正向耦合关系,中东部地区中心城市是引领数字经济创新的主要力量;③中国数字经济创新水平受到创新要素投入和创新活动的空间溢出效应的共同作用.其中,大学、数字基础设施等非流动性要素仅对本地数字经济创新具有促进效应,而知识、人力资本等流动性要素的促进作用还会溢出到邻近城市.据此,提出了优化中国数字经济区域创新格局、完善创新要素配置体制机制和促进创新成果转变为发展效能的政策建议.
Evolution and Driving Mechanism of the Spatial Pattern of Digital Economy Innovation in China
Based on the invention patent authorization data of China from 2006 to 2020,and taking cities at prefecture level and above as the analysis unit,this paper explored the spatiotemporal pattern characteristics of digital economy innovation in China,revealed its driving mechanism with constructing spatial panel data from the perspective of knowledge production functions using the spatial Durbin model.The study found that:1)Digital economic innovation has increasingly became an important sector in innovation activities,and showed significant spatial imbalance characteristics,as with higher spatial concentration than all innovation activities.2)There was a positive coupling relationship between digital economic innovation and urban innovation capabilities.Central cities in the central and eastern regions were the main force leading digital economic innovation.3)The innovation level of digital economy was affected by the joint effects of innovation factor input and the spatial spillover of innovation activities.Non-mobile elements such as universities and digital infrastructure only promote local digital economic innovation,while which of mobile elements such as knowledge and human capital will spill over to neighboring cities.Based on the conclusions,it puts forward policy recommendations to optimize the regional innovation pattern of China's digital economy,improve the institutional mechanism for the allocation of innovation factors and promote the transformation of innovation achievements into development effectiveness.
