Abstract:

The rise of the digital economy has provided an important opportunity for the coordinated development of the region. Based on the data of 284 prefecture-level cities in China， this paper constructs a transmission mechanism to examine the direct， indirect and regulatory effects of the digital economy on regional disparities， and the mediating effect method of Bootstrap is adopted. The research shows that: The spatial distribution of the digital economy， manufacturing agglomeration and regional disparity are characterized by the imbalance of “The south is stronger while the north，weaker” and “The east is stronger while the west，weaker”; The digital economy has a negative direct effect on regional disparities; The digital economy has exerted a significant positive mediating effect on the regional disparities through the agglomeration economy; Fiscal spending on science and education plays a negative regulatory effect in the direct path， and plays a positive adjustment effect in the process of the digital economy affecting the agglomeration economy. The policy meaning is that to narrow the regional gap in the era of digital economy， it is necessary to promote digital technology and eliminate the digital divide， and it is also necessary to improve the institutional supporting mechanisms such as factor flow and fiscal spending on science and education.

Key words: digital economy, regional disparity, agglomeration economy, spatial distribution, bootstrap method

摘要：

数字经济的兴起为实现地区协调发展提供了重要契机。基于中国284个地级市数据，通过构建传导机制考察数字经济对地区差距的直接、间接和调节效应，采用Bootstrap有调节的中介效应方法进行分析。研究表明：数字经济、制造业集聚和地区差距的空间分布均呈现“东强西弱、南强北弱”的不均衡特征；数字经济对地区差距具有负向的直接效应；数字经济通过集聚经济对地区差距发挥了显著的正向中介效应；财政科教支出在直接路径中发挥负向的调节效应，在数字经济影响集聚经济过程中发挥正向调节效应。如须在数字经济时代下缩小地区差距，既需要推广数字技术、消弭数字鸿沟，也需要完善要素流动、财政科教支出等制度性配套机制。
