摘要: 提升产业链供应链韧性是经济高质量发展的重要内容。建设数字中国是数字时代推进中国式现代化的重要引擎,而数字基础设施作为数字经济的支撑,如何赋能产业链供应链韧性有必要深入考察。基于2007—2021年中国A股上市公司数据,采用双重差分模型考察数字基础设施建设对产业链供应链韧性的影响及作用机制。研究发现,数字基础设施建设显著提升了产业链供应链韧性。机制分析发现,数字基础设施建设通过供应链网络拓展效应、企业创新效应、空间距离挤压效应推动产业链供应链韧性提升。异质性拓展分析发现:数字基础设施的产业链供应链韧性提升效应具有空间非均衡性,东部地区数字基础设施建设的产业链供应链韧性提升效应更明显;数字基础设施建设对小企业、低研发强度企业、数字化转型程度低的企业、劳动密集型企业的产业链供应链韧性的提升效应更强;数字基础设施建设显著降低了产业链供应链集中度。

Abstract: Enhancing the resilience of industrial and supply chains is a key element in achieving high-quality economic development. The construction of a Digital China serves as a crucial engine for advancing Chinese-style modernization in the digital era. As the backbone of the digital economy, the role of digital infrastructure in empowering the resilience of industrial and supply chains warrants in-depth investigation. Based on the data from Chinese A-share listed companies from 2007 to 2021, this paper applies a difference-in-differences (DID) model to examine the impact of digital infrastructure development on enhancing the resilience of industrial and supply chains, as well as the underlying mechanisms. The findings reveal that digital infrastructure can significantly improve the resilience of industrial and supply chains. The mechanism analysis indicates that digital infrastructure promotes the resilience through the expansion effect of supply chain networks, the innovation effect of firms, and the compression effect of spatial distance. The heterogeneity extended analysis shows spatial non-uniformity in the resilience enhancement effect of digital infrastructure, with a more pronounced effect in the eastern region. Furthermore, digital infrastructure development has a stronger resilience-enhancing effect on the small firms, the firms with low R&D intensity, the firms with low degrees of digital transformation, and the firms in labor-intensive industries. The construction of digital infrastructure has significantly reduced the concentration of industrial and supply chains.

Key words: industrial and supply chain resilience, digital infrastructure, supply chain network, industrial and supply chain concentration
