摘要
本文采用2011—2020年南北方城市面板数据,使用动态空间面板杜宾模型(SPDM)考察了数字金融通过产业结构调整对南北经济高质量发展的空间溢出效应,并利用面板平滑转换(PSTR)模型探讨了数字金融对南北方高质量发展的非线性影响。研究发现,数字金融通过产业结构调整对南方的空间溢出效应显著大于北方,虽然南北方溢出效应都表现出空间衰减特征,但溢出效应的差异在空间溢出密集区域尤为明显,而南北技术创新、资本积累和劳动力数量日益凸显的差距是差异产生的重要原因.此外,在产业结构路径的调节下,数字金融会对南北方高质量发展产生驱动作用,随着PSTR模型由低区制向高区制的平滑转换,驱动作用不断增强,并且南方的驱动作用显著大于北方。
Using the panel data of southern and northern cities from 2011 to 2020,this paper examines the spatial spillover effect of digital finance on high-quality economic development in the North and the South through industrial structure adjustment adopting dynamic spatial panel Durbin model(SPDM).Meanwhile this paper uses panel smooth transition regression(PSTR) model to explore the nonlinear impact of digital finance on high-quality development of the North and the South.The research finds that the spatial spillover effect of digital finance on high-quality economic development in the South through industrial structure adjustment is significantly greater than that of the North.Although the northern and southern spillover effects show the characteristics of spatial attenuation,the difference of spillover effects is particularly obvious in the regions with intensive spatial spillovers.While the increasingly prominent gap between the South and the North in technological innovation,capital accumulation and labor quantity are important reasons for the difference.In addition,under the adjustment of the industrial structure,digital finance plays a driving effect in highquality development of the North and the South.With the smooth transition of the PSTR model from a low regional system to a high regional system,the driving effect is growing,and the driving effect of the South is significantly greater than that of the North.
