Abstract
En 中文
Organizations have become increasingly ethnically diverse, and this diversity often brings together distinct technological competencies. Understanding how firms can leverage such diversity to produce valuable innovations therefore becomes essential. This study investigates how ethnic integration within inventor collaboration networks, and its interaction with ethnic diversity, influence the economic value of innovation. Using patent and co-inventor data from 890 publicly traded U.S. firms (1990–2015), we construct a network-based index of ethnic integration, defined as the ratio of cross-ethnic to within-ethnic co-invention ties, and link it to stock market reactions surrounding patent grants. We find that ethnic integration significantly enhances patent value, particularly in firms that are both ethnically diverse and engaged in technologically complex innovation. These findings are robust to an instrumental-variables strategy addressing potential endogeneity concerns. By distinguishing between workforce composition and collaborative structure, our study advances the literature on diversity and innovation and underscores the critical role of integration mechanisms in unlocking the full potential of diverse organizations.
