Abstract

Governance for reliability has gained prominence in the post-COVID era. However, it remains unclear whether supplier concentration enhances reliable efficiency amidst supply chain risks, especially during catastrophic risks like the COVID-19 pandemic. Our research leverages the COVID-19 pandemic to assesses the impacts of supplier concentration by analyzing data from 1870 Chinese listed firms from 2017 through 2022. The results reveal a significant decline in operational efficiency as the severity of the pandemic increases, with this decline being more pronounced among firms with high supplier concentration. However, the negative interactive impact of supplier concentration and pandemic severity decreases when firms possess high levels of digitalization or relational ties. These findings highlight the importance of distinguishing between different types of supply chain risks when assessing the impact of supplier concentration and reveals risk-mitigating strategies that firms can adopt to navigate the paradoxical effects of supplier concentration amid catastrophic risks.

灾难性风险期间的供应商集中度和运营效率

在后新冠时代，可靠性治理变得尤为突出。然而，目前尚不清楚供应商集中是否能在供应链风险中提高可靠的效率，特别是在COVID-19大流行等灾难性风险中。我们的研究通过分析2017年至2022年1870家中国上市公司的数据，利用COVID-19大流行来评估供应商集中度的影响。结果显示，随着疫情严重程度的增加，运营效率显著下降，在供应商集中度较高的公司中，这种下降更为明显。然而，当企业拥有高水平的数字化或关系关系时，供应商集中度和流行病严重程度的负面互动影响会降低。这些发现强调了在评估供应商集中的影响时区分不同类型供应链风险的重要性，并揭示了企业可以采用的风险缓解策略，以应对供应商集中在灾难性风险中的矛盾效应。
