六、内容简介：

We examine the impact of the China-U.S. tech war on Chinese domestic corporate innovation. We use the China-U.S. tech war as a natural experiment, which bans American firms from exporting high-tech products and technologies to sanctioned Chinese companies by adding nearly 500 Chinese entities to the Entity List. However, as for the domestic potential suppliers of the entity-listed Chinese companies, the China-U.S. tech war reduces import competition and expands domestic market size from American suppliers, which spurs corporate innovation. We first employ a difference-in-differences identification strategy to show that the domestic potential suppliers, especially those far from the frontier, see an increase in R&D since the China-U.S. tech war, driven by reduced import competition and market expansion. Further analyses show that the positive effect is stronger in firms with higher human capital, and non-state ownership. Second, we also find that the domestic potential suppliers see an increase in invention patents granted. In addition, the positive effect translates into significant firm value gains. We suggest our results as evidence that the positive impact of the tech war propagates through the global supply chain. Although the China-U.S. tech war deals a severe blow to the entity-listed firms, it stimulates innovation and brings unexpected benefits to upstream Chinese firms.
