Abstract
This thesis examines the domestic innovation effects of the October 2022 U.S. semiconductor export controls, focusing on the tradeoff between national security objectives and firm-level competitiveness. By restricting exports of advanced chips and semiconductor manufacturing equipment to China, these controls may limit cross-border revenue opportunities and natural channels of knowledge transfer. However, the innovation response of affected firms is theoretically ambiguous: reduced access to foreign markets may depress revenues and lead firms to scale back R&D expenditures as a percentage of gross revenue, thus dampening innovation intensity, or, alternatively, firms may sustain or even increase R&D allocations to overcome trade barriers, preserve technological leadership, and adapt to a more fragmented global market. To test these competing hypotheses, this study employs an econometric difference-in-differences framework, estimating the effect of treatment status—exposure to the October 2022 controls—on two firm-level outcomes: Other Intangibles (including patents, trademarks, and copyrights) and R&D expenditure, both of which are log-transformed to account for skewness and enable within-firm comparison. The analysis finds that export controls do not have a significant impact on firm-level innovation inputs or outcomes.
