Policy Implications of the Biden Administration’s Global Supply Chain Reorganization

This study indirectly estimates the impact of implementation of the Biden government’s supply chain restructuring policy on the U.S. and Korean economies, and derives policy implications accordingly. For the first analysis to indirectly examine the economic impact of the global supply chain reorganization of the semiconductor and battery industries, we estimate the impact of changes in the export share of the semiconductor or battery industry by country on the change in GDP per capita. Our results show an increase in the export share of semiconductors or batteries has a statistically significant increase in GDP per capita. These results support the reason why the Biden administration is moving to expand its exports through the reorganization of the U.S.-centered supply chain in the industry. By reorganizing the supply chain centered on the U.S., President Biden intends to attract production facilities in weak sectors such as memory semiconductors, foundries, and lithium-ion battery manufacturing to the U.S. through cooperation with partner countries such as Taiwan and Korea in the short term. In conclusion, this policy promotion seems to be part of a strategy to discover sustainable economic growth engines for the U.S. while checking China’s technological rise in key industries, and restoring U.S. leadership. Secondly, we estimate the impact of changes in export concentration or import concentration by semiconductor or battery item in the U.S. and Korea on the change in net exports by the two countries. First of all, in the case of the U.S. semiconductor industry, changes in export concentration and import concentration did not have a statistically significant effect on changes in net exports of the corresponding item. However, in the case of the Korean semiconductor industry, an increase in export concentration had a negative impact on the net export of the item, whereas a change in import concentration did not have a statistically significant effect on the change in Korea’s net export of the same item. In the case of the U.S. battery industry, as the import concentration by item increases, the U.S. net export of the same item decreases. However, we find that both the increase in the concentration of exports and the concentration of imports in the Korean battery industry decrease net exports of the product.
