Semiconductor Export Controls and Innovation in the U.S.-China Technology War

简介 |
<p>We document new empirical facts on how semiconductor innovation affects downstream innovation in the United States and China. Motivated by these facts, we develop and estimate a two-country endogenous growth model in which semiconductor firms innovate strategically and downstream firms use semiconductors as essential inputs into innovation. We use the model to quantify the effects of U.S. semiconductor export controls. Export controls raise innovation in U.S. semiconductor and downstream sectors in the short run, but reduce innovation in both sectors in the long run, regardless of whether the United States widens its technological lead over China. The short-run gains reflect greater domestic semiconductor supply and stronger escape-competition incentives, while the long-run losses arise from reduced access to the Chinese market. Export controls also narrow the U.S. downstream trade deficit, and AI-driven downstream productivity growth amplifies short-run gains while mitigating long-run losses.</p> |
