Abstract: This article calculates the “chain leader” index of the industrial chain based on the input-output table and the list of leading manufacturing enterprises, and uses the data of listed companies from 2007 to 2022 to evaluate the impact of the “chain leader” of the industrial chain on the resilience of the enterprises. The results show that the “chain leader” of the industrial chain significantly improves the resilience of local enterprises, and the conclusion is still valid after further considering the robustness issues such as sample range, index measurement, and endogenous problems. The mechanism research shows that the “chain leader” of the industrial chain can improve the resilience of enterprises by reducing their operating costs, improving their innovation capacity, and promoting supply chain integration, and digital reform will strengthen their resilience with increasing effect. The extended analysis shows that the resilience improvement of coastal areas, high-tech enterprises and enterprises participating in the domestic cycle is more significant. The research in this paper is of great and practical significance for cultivating “chain leader” enterprises and exploring the governance path of industrial chain and supply chain security.

Key words: Industry Chain Leader, Enterprise Resilience, Innovation Level, Supply Chain Collaboration, Digitalization

摘要： 本文结合投入产出表和制造业龙头企业名单测算产业链“链主”指标,采用2007—2022年上市公司年报数据评估产业链链主对企业韧性的影响。研究发现,产业链链主显著提升企业韧性,在考虑样本范围、指标测度等稳健性及内生性问题后结论依然成立;产业链链主通过减少企业经营成本、提高企业创新水平、降低供应链集中度等渠道提升企业韧性,数字化转型强化企业韧性的提升效应;沿海地区、高技术水平及参与国内大循环的企业韧性提升更显著。这一研究对培育链主企业、探索产业链供应链安全的治理路径具有重要的现实意义。
