近年来,全球化趋势逆转或减缓,显现出贸易保护主义兴起、全球价值链重构和地缘政治紧张等特征,给国际贸易带来更多不确定性与风险,对我国产业链和供应链安全性构成挑战。在这复杂环境下,提升产业链韧性已成为保障我国经济健康发展的要求。数字经济的崛起成为21世纪全球经济的重要动力,其广泛应用正深刻改变传统产业链格局,同时带来新的挑战和机遇。本文基于2010年至2021年我国30个省份和各地市的面板数据,旨在探讨数字经济对产业链韧性的影响。本研究的边际贡献在于拓展了数字经济对产业链韧性影响的实证研究,采用固定效应模型考察各地级市和年份对模型的影响,为政府提供了促进产业链韧性提升的依据,同时为数字经济助力经济高质量发展提供启示。实证分析结果显示,数字经济发展水平与高新技术产业链的韧性呈正相关,验证了数字经济对产业链韧性的赋能作用。In recent years, the trend of globalization has reversed or slowed down, showing the rise of trade protectionism, the reconstruction of global value chain and geopolitical tension, which brings more uncertainty and risks to international trade and poses challenges to the safety of China’s industrial chain and supply chain. In this complex environment, improving the toughness of industrial chain has become a requirement to ensure the healthy development of China’s economy. The rise of digital economy has become an important driving force for the global economy in the 21st century, and its wide application is profoundly changing the traditional industrial chain pattern, while bringing new challenges and opportunities. Based on the panel data of 30 provinces and cities in China from 2010 to 2021, this paper aims to explore the impact of digital economy on the toughness of industrial chain. The marginal contribution of this study lies in expanding the empirical research on the impact of digital ec
