摘要: 为探究数字金融发展水平与区域创新之间的关系,基于我国2011—2018年省际面板数据,采用空间杜宾模型研究数字金融对区域创新效率的影响及其作用机制。结果表明:区域创新效率具有一定的空间溢出性,并且各地区之间的创新活动存在竞争效应。数字金融发展水平的提升可以提高本地区创新效率,但邻近地区数字金融发展则会抑制本地区创新效率。根据中介效应模型的估计结果,数字金融发展主要通过扩大金融规模和产业结构升级提高区域创新效率。最后,基于以上研究分地区进行异质性分析并提出政策建议。

关键词: 区域创新效率, 数字金融, 空间杜宾模型;中介效应

Abstract: The spatial Durbin model (SDM) is used to study the impact of digital finance on regional innovation efficiency and its mechanism based on Chinas provincial panel data from 2011 to 2018 The results show that regional innovation efficiency has a certain spatial spillover, and a competitive effect exists in innovation activities from various regions The improvement of the development level of digital finance can improve innovation efficiency of the region, but the development of digital finance in neighboring regions will inhibit innovation efficiency of the region According to the estimated results of the intermediary effect model, the development of digital finance improves the efficiency of regional innovation mainly through the expansion of financial scale and the upgrading of industrial structure Finally, based on the above research and its heterogeneity analysis, policy recommendations are put forward in light of different regions.
