Semiconductors and modern industrial policy

Semiconductors have emerged as a headline in the resurgence of modern industrial policy. This paper explores the political economic history of the sector, the changing nature of the semiconductor supply chain, and the new sources of concern that have motivated the most recent turn to government intervention. It also explores details of that turn to industrial policy by the United States, China, Japan, Europe, South Korea, and Taiwan. Modern industrial policy for semiconductors has included not only subsidies for manufacturing, but also new import tariffs, export controls, foreign investment screening, and antitrust actions.
