数字经济对区域经济协调发展的影响效应及作用机制研究

Research on the Effect and Mechanism of Digital Economy on the Coordinated Development of Regional Economy

作为新经济形态的数字经济不仅为区域经济增长注入新动能,更成为推进区域经济协调发展的重要契机。本文基于数字经济发展的新特征,提出了数字经济影响区域经济协调发展的直接效应,包括空间溢出效应、技术泛化效应和驱动传导效应,以及数字经济影响区域经济协调发展的市场化和劳动力资源配置的间接效应。在此基础上,收集整理了我国2013—2019年284个地级市相关数据,主要运用系统GMM方法、中介效应方法进行实证检验。结果显示:数字经济不仅从整体上促进了我国区域经济协调发展,而且能够通过提高市场化水平和改善劳动力资源配置缩小区域经济差距。在分地区回归中,数字经济均显著缩小了东中西部区域经济发展差距,并且对东部城市的影响效应最为显著。

As a new economic form,digital economy not only injects new momentum for regional economic growth,but also becomes an important opportunity to promote coordinated regional economic development.Based on the new characteristics of digital economy development,this paper proposes the direct effects of digital economy affecting coordinated regional economic development,including spatial spillover effect,technology generalization effect and driving conduction effect,as well as the indirect effects of digital economy affecting coordinated regional economic development in terms of marketization and labor resource allocation.On this basis,data related to 284 prefecture-level cities in China from 2013 to 2019 were collected and compiled,and empirical tests were conducted mainly by SYS-GMM method and Mediating Effects method.The results show that the digital economy not only promotes the coordinated development of China’s regional economy as a whole,but also can narrow the regional economic gap by increasing the level of marketization and improving the allocation of labor resources.In the sub-regional regressions,the digital economy significantly reduces the regional economic development gap in the east,middle and west of China,and has the most significant effect on the eastern cities.
