摘要
文章基于我国2011—2019年285个地级及以上城市的面板数据,运用空间计量模型和中介效应模型对数字普惠金融、科技创新与产业结构优化的影响机制、空间效应和区域异质性进行分析。结果表明:数字普惠金融的快速发展对产业结构优化具有显著影响,并且科技创新是其中的不完全中介,三者之间均存在空间溢出效应;本地区三者之间的交互影响是正向的,但对非本地区却呈现抑制作用,产生虹吸效应;以上影响机制具有明显的异质性,东部和西部地区三者之间相互关系与整体基本一致,且影响效应更强,但无论是否考虑中介效应,中部地区的影响均不明显。
Based on the panel data of 285 cities at prefectural level and above in China from 2011 to 2019,this paper uses spatial econometric model and mediating effect model to study and analyze the impact mechanism,spatial effect and regional heterogeneity of digital inclusive finance,technological innovation and industrial structure optimization.The results go as below:The rapid development of digital inclusive finance has a significant impact on the optimization of industrial structure;technological innovation is an incomplete intermediary,and there is a spatial spillover effect among the three.The interaction between the three is positive in this region,but it shows inhibitory effect and siphon effect in non-local regions.The above impact mechanisms have obvious heterogeneity.The relationship between the eastern and western regions is basically consistent with the whole,and the impact is stronger.However,whether the mediating effect is considered or not,the influence of the central region is not obvious.
