The impact of the US export controls on Chinese firms' innovation: Evidence from Chinese high-tech firms

Using a sample of Chinese high-tech firms from 2007 to 2020, this study investigates the impact of U.S. export control regulations (ECRs) on Chinese high-tech firms' innovation. The results reveal that U.S. ECRs force Chinese firms to increase their R&D inputs and outputs. Moreover, the findings illustrate that technology dependence and import competition act as mechanisms to mediate such trade effects. Our cross-sectional analyses indicate that the positive relationship between U.S. ECRs and Chinese firms' innovation strengthens in firms importing more high-tech products, with better innovation accumulation, with fewer financial constraints, or with more financial subsidies. Fundamentally, this study complements the literature on the U.S.-China trade war and offers policy implications for the Chinese government.
