講座摘要:
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.
本研究探討了公司在面對(duì)美國對(duì)供應(yīng)商限制時(shí)如何調(diào)整其供應(yīng)鏈配置的問題。通過使用全面的全球供應(yīng)鏈數(shù)據(jù)和差異化模型,我們發(fā)現(xiàn)公司不僅會(huì)與受限制的供應(yīng)商斷絕聯(lián)系,還會(huì)減少與受限制國家中非受限制供應(yīng)商的聯(lián)系。為了增強(qiáng)韌性,公司拓寬了供應(yīng)商基礎(chǔ),并增加了地理多樣化,通常將供應(yīng)商遷移到擁有區(qū)域貿(mào)易協(xié)議的國家,以減輕貿(mào)易中斷帶來的影響。我們的分析揭示了顯著的異質(zhì)性:來自受限制地區(qū)的公司通常會(huì)選擇本土化生產(chǎn),導(dǎo)致利潤和銷售減少,而來自非受限制地區(qū)的公司則通過外包和多元化經(jīng)營,財(cái)務(wù)影響較小。值得注意的是,美國公司在調(diào)整方面表現(xiàn)較少,且在運(yùn)營和財(cái)務(wù)上幾乎不受影響。通過結(jié)合風(fēng)險(xiǎn)和經(jīng)濟(jì)效率,本研究為理解在制約條件下供應(yīng)鏈重組提供了框架,并為全球供應(yīng)鏈管理提供了洞見。
