区域数字经济发展差距的内生机理与空间效应——以环京津冀省份为例

Endogenous Mechanism and Spatial Effect of Regional Digital Economy Development Gap——Taking the Provinces Around Beijing, Tianjin and Hebei as an Example

剖释区域数字经济发展差距的内生机理与影响机制,基于环京津冀12省份2011—2021年面板数据建立空间计量模型,考察影响区域数字经济发展差距的空间效应。研究表明:数字经济作为区域经济组成部分,呈现核心-边缘发展模式;实证检验表明信息通信产业存在极化效应,扩大了区域数字经济发展差距,本地网络基础设施缩小了发展差距;异质性检验表明环京津冀内环省份信息通信产业、网络基础设施和数据要素均缩小了差距,数字技术极化效应扩大了差距。外环省份中信息通信产业和数据要素扩大了差距,网络基础设施和数字技术影响不显著。通过推动数字经济集群发展,发挥空间溢出效应,加强网络基础设施建设,加大数字技术研发投入力度,规范数据交易市场,继而实现区域数字经济协调发展。

This paper explains the endogenous mechanism and influence mechanism of the regional digital economy development gap,establishes a spatial econometric model based on the panel data of 12 provinces around Beijing,Tianjin and Hebei from 2011 to 2021,and investigates the spatial effect that affects the regional digital economy development gap.The research shows that digital economy,as an integral part of regional economy,presents a core-periphery development model;the empirical test shows that there is polarization effect in information and communication industry,which widens the development gap of regional digital economy and reduces the development gap by local network infrastructure.Heterogeneity test shows that the information and communication industry,network infrastructure and data elements in the inner ring provinces around Beijing,Tianjin and Hebei have reduced the gap,and the polarization effect of digital technology has widened the gap.The gap between information and communication industry and data elements in the outer ring provinces and cities has widened,and the network infrastructure and data technology are not significant.By promoting the development of digital economic clusters,giving full play to the spatial spillover effect,strengthening network infrastructure,increasing investment in digital technologies,and standardizing the data trading markets,the coordinated development of regional digital economy will be realized.
