讲座摘要：

This study examines how firms adapt their supply chain configurations in response to US sanctions on suppliers. Using comprehensive global supply chain data and a difference-in-differences model, we find that firms not only sever ties with sanctioned suppliers but also reduce connections with non-sanctioned suppliers in sanctioned countries. To enhance resilience, firms broaden their supplier bases and increase geographic diversification, often relocating suppliers to countries with regional trade agreements to mitigate trade disruptions. Our analysis reveals significant heterogeneity by firm origin: companies in sanctioned regions frequently reshore, incurring reduced profitability and sales, while those in non-sanctioned regions pursue offshoring and diversification with minimal financial impact. Notably, US-based firms exhibit fewer adjustments and are largely unaffected operationally and financially. By integrating political risk and economic efficiency, this study provides a framework for understanding strategic supply chain reconfiguration under geopolitical constraints, offering insights for global supply chain management.

本研究探讨了公司在面对美国对供应商限制时如何调整其供应链配置的问题。通过使用全面的全球供应链数据和差异化模型，我们发现公司不仅会与受限制的供应商断绝联系，还会减少与受限制国家中非受限制供应商的联系。为了增强韧性，公司拓宽了供应商基础，并增加了地理多样化，通常将供应商迁移到拥有区域贸易协议的国家，以减轻贸易中断带来的影响。我们的分析揭示了显著的异质性：来自受限制地区的公司通常会选择本土化生产，导致利润和销售减少，而来自非受限制地区的公司则通过外包和多元化经营，财务影响较小。值得注意的是，美国公司在调整方面表现较少，且在运营和财务上几乎不受影响。通过结合风险和经济效率，本研究为理解在制约条件下供应链重组提供了框架，并为全球供应链管理提供了洞见。
