摘要
全球供应链频繁受到各类风险冲击而韧性不足的问题日益突出，数字技术的发展与创新为解决这一难题提供了新方法与工具，两者的关联亟待深入研究。本文选取2010-2022年间沪深A股上市公司为研究样本，构建综合指标体系量化企业供应链韧性水平，采用双向固定效应模型和两阶段最小二乘法（2SLS），从微观层面探讨数字技术创新对企业供应链韧性的影响和内在机制。研究表明，企业数字技术创新显著提升供应链韧性（系数为0.0488，在1%水平上显著），并通过增加企业数据资产与提升价值创造效率间接提高供应链韧性。异质性分析结果显示，数字技术创新对供应链韧性的增强作用在处于东部、中部地区的企业和中小型企业中更为明显。研究结果从动态能力理论视角理解企业数字技术创新强化供应链韧性的过程，为企业通过数字技术创新提升自身竞争力提供了实践依据，同时为数字化背景下助力产业链供应链高质量发展提供理论支撑。

Abstract
The problem of insufficient resilience in global supply chains, which are frequently hit by various risks, has become increasingly prominent. The development and innovation of digital technologies has provided new methods and tools to address this challenge, and the connection between the two needs in-depth research. This paper selects A-share listed companies in Shanghai and Shenzhen from 2010 to 2022 as research samples, constructs a comprehensive indicator system to quantify the resilience level of enterprises' supply chains, adopts the two-way fixed effects model and two-stage least squares (2SLS) method, and explores the impact and internal mechanism of digital technology innovation on enterprises' supply chain resilience from a micro perspective. The research shows that enterprises' digital technology innovation significantly improves supply chain resilience (with a coefficient of 0.0488, significant at the 1% level), and indirectly enhances supply chain resilience by increasing enterprises' data assets and improving the efficiency of value creation. The results of heterogeneity analysis indicate that the enhancing effect of digital technology innovation on supply chain resilience is more obvious in enterprises in the eastern and central regions as well as in small and medium-sized enterprises. The research findings help understand the process of enterprises' digital technology innovation strengthening supply chain resilience from the perspective of dynamic capability theory, provide a practical basis for enterprises to enhance their competitiveness through digital technology innovation, and offer theoretical support for promoting the high-quality development of industrial chains and supply chains in the digital age.
Key words： Digital innovation; Supply chain resilience; Data assets; Value creation efficiency
