数字经济对长三角地区城市经济韧性的影响研究

The Impact of Digital Economy on Urban Economic Resilience in the Yangtze River Delta Region

新发展格局下,加快数字经济发展、增强城市经济韧性是实现区域经济高质量发展的重要途径。基于2011—2019年长三角地区41个城市的面板数据,实证研究数字经济对长三角城市经济韧性的影响效果及作用路径,结果表明:(1)基准检验发现,数字经济发展能够显著提升长三角城市的经济韧性,并且对城市经济抵抗与恢复力的提升效果最明显。(2)异质性分析发现,数字经济发展对长三角都市圈内城市经济韧性的促进效果显著。(3)中介效应检验发现,数字经济发展可以通过促进创新创业和改善社会保障两条路径来提升城市经济韧性。(4)空间效应检验发现,数字经济发展对长三角城市群内邻近城市经济韧性存在正向溢出效应。由上可见,为了更好地发挥数字经济发展对经济韧性提升的作用,有关方面应当推动数字经济与实体经济融合发展,促进数字经济与社会保障体系联动发展,加快都市圈人才引进,以及加强非都市圈城市数字经济建设力度。
