Escaping Product Market Rivalry Through Innovation
研究中国进口竞争如何加剧美国电子电器企业的产品市场竞争，并促使它们增加专利产出、开发新产品并战略性地进入新领域。
This study leverages advanced text-analysis techniques to investigate how increased product market rivalry, induced by Chinese import competition, affects innovation among incumbent U.S. firms in the electronic and electrical appliance industry. We measure the similarity between the product descriptions of U.S. firms and those of Chinese importers, thus capturing firm-level competitive pressure. Employing a continuous difference-in-differences framework, we compare innovation outcomes of U.S. firms more directly competing with Chinese importers to those facing lower competitive pressure over a five-year period before and after initial Chinese market entry. We find that incumbent U.S. firms significantly increase their quality-weighted patent production, create more new-product patents, and strategically diversify into new technological and business segments when confronted with heightened competition. Our findings highlight the role of import-driven rivalry in stimulating strategic innovation and illustrate how text-based similarity measures can effectively quantify firm-level competition, providing novel methodological tools for strategy scholars.
