内容简介:

The use of economic sanctions as a means of addressing international disputes has become increasingly prevalent in recent years, causing significant uncertainty within global supply chain networks. This study examines the impact of economic sanctions on the restructuring of global supply chains, leveraging the United States' sanction activities as quasi-natural experiments. Employing a difference-in-differences model, we investigate how firms connected to sanctioned entities through supply chains adjust their global supplier networks. Our findings reveal several stylized effects. Firstly, firms demonstrate a tendency to increase both the number and geographic diversification of their suppliers, featuring a combination of more termination and establishment of suppliers. Secondly, we observe heterogeneity in supply chain adjustment strategies. Firms located in sanctioned countries, such as China and Russia, tend to relocate suppliers to their home countries. In contrast, firms situated in non-sanctioned countries, such as the United States and the United Kingdom, tend to reallocate suppliers to countries that maintain favorable political relationships with the U.S. or their main revenue-generating countries. Lastly, we find that firms politically connected with the United States government experience minimal disruptions compared to other firms.
