摘　　要：产业链韧性是现代化产业结构发展的根基,交通是要素流动的主要载体,高铁作为交通运输现代化的重要标志,其网络发展水平将直接影响产业链韧性。基于新经济地理学、交通外部性以及产业组织等理论,利用2012−2021年中国287个地级及以上城市面板数据,检验高铁网络对城市产业链韧性的作用效果及数字化水平对这一作用效果的调节效应。结果表明:高铁网络发展能够有效提升地区产业链韧性,其提升效果为1.68%,同时数字化发展作为调节效应强化了该作用的影响效果;高铁网络发展通过提升创新集聚与创业活跃度增强了产业链韧性;异质性分析还发现,当城市位处西部地区、北方地区或者非国家中心城市时,高铁网络对产业链韧性的提升作用更强。基于此,各地应因地制宜,积极融入中国内生发展时代的高铁网,大力推动地区数字化建设,充分发挥创新集聚和创业活跃度的渠道作用,为企业创造更包容的发展环境,为实现产业链高质量发展提供新的动力机制。The resilience of the industrial chain underpins the development of modern industrial structures.Transportation serves as the primary carrier for factor mobility,and high-speed rail,as a pivotal maker of transportation modernization,exerts a direct influence on industrial chain resilience through its network development.Drawing on new economic geography,transportation externalities,and industrial organization theories,this study utilizes panel data from 287 Chinese cities at the prefecture level and above from 2012 to 2021 to examine the impact of high-speed rail network on urban industrial chain resilience and the moderating role of digitalization.The results indicate that the development of high-speed rail network effectively enhances regional industrial chain resilience by approximately 1.68%.Moreover,digital development amplifies this positive effect as a moderating factor.Specifically,the development of high-speed rail network strengthens industrial resilience by fostering innovation agglomeration and boosting entrepreneurial activity.Furthermore,a heterogeneity analysis indicates that the positive impact of high-speed rail on industrial resilience is even more pronounced in cities located in western and northern regions or those that are not national central cities.Consequently,regions should tailor their strategies to leverage China’s high-speed rail network in the era of endogenous development,vigorously promote regional digitalization,and fully exploit the benefits of innovation agglomeration and entrepreneurial activity.This approach will create a more conductive environment for enterprises and provide fresh momentum for achieving high-quality development of the industrial chain.
