数字经济是否提升了城市韧性?——来自中国285个城市的经验证据

Is the Digital Economy Making Cities more Resilient?——Empirical Evidence from 285 Chinese Cities

当前世界格局下,加快数字经济发展、提升城市韧性水平对于实现城市可持续发展具有重要意义。基于2011—2020年全国285个地级及以上城市的面板数据,测度数字经济发展水平与城市韧性水平,运用面板固定效应模型、中介效应模型实证分析数字经济对城市韧性的影响,结果表明,数字经济可以有效促进城市韧性水平的提高,地理区位和行政等级的不同会影响数字经济促进城市韧性的效果,作用机制是数字经济可以通过提高城市创业活跃度、技术创新水平和人力资本水平来提升城市韧性。为充分发挥数字经济发展对城市韧性的提升作用,应加快“数字中国”建设进程,释放数字经济发展红利,重视教育水平的提高,注重技术创新,优化城市创业环境。

In the current world situation,it is important to accelerate the development of digital economy and improve the level of urban resilience to achieve sustainable urban development.Based on the panel data of 285 prefecture-level cities and above from 2011 to 2020.This paper measures the level of digital economy development and the level of urban resilience,and empirically analyze the impact of digital economy on urban resilience using panel fixed-effects model,mediating-effects model.The results show that the digital economy can effectively contribute to the improvement of urban resilience,and the difference in geographic location and administrative level affects the effect of the digital economy on urban resilience,and the mechanism of action is that the digital economy can improve urban resilience by increasing urban entrepreneurial activity,technological innovation and human capital.In order to give full play to the role of digital economy development in improving urban resilience,it is necessary to accelerate the process of“Digital China”construction,release the dividends of digital economy development,pay attention to the improvement of education level,focus on technological innovation,and optimize the urban entrepreneurial environment.
