Research on the Impact of Digital Technology Innovation on the Resilience of High-Tech Industrial Chains

本文利用2010~2023年省份层面数字技术专利数据，并构建高技术产业链韧性指标体系，系统研究了数字技术创新与高技术产业链韧性之间的关系。研究发现：数字技术创新能显著提升高技术产业链韧性，且这种影响在区域和技术演进阶段层面存在异质性。实证研究还表明，数字技术创新通过专利知识宽度和新型基础设施建设正向影响高技术产业链韧性。据此，本文提出了聚焦技术类型与关键环节、强化技术演进阶段适配与区域协同和紧扣“以数强链”数字化转型关键抓手等针对性政策建议。This paper utilizes digital technology patent data at the provincial level from 2010 to 2023 and constructs a high-tech industry chain toughness index system to systematically study the relationship between digital technology innovation and high-tech industry chain toughness. The study finds that digital technology innovation can significantly enhance the resilience of high-tech industrial chains, and this impact varies across regions and stages of technological evolution. Empirical research also indicates that digital technological innovation positively influences the resilience of high-tech industrial chains through patent knowledge breadth and the construction of new infrastructure. Based on this, this paper proposes targeted policy recommendations that focus on technology types and key links, strengthen the adaptation of technology evolution stages and regional coordination, and closely follow the key drivers of digital transformation “to strengthen the chain with data”.
