Specialization as a double‐edged sword: The relationship of scientist specialization with R&D productivity and impact following collaborator change
研究了科学家专业化程度如何影响企业的研发生产力和创新影响力，发现专业化提升生产力但降低影响力，而合作者变动会逆转这一关系，为管理者平衡研发绩效提供策略参考。
Abstract Research Summary Organizational learning studies demonstrate that specialization conditions multiple aspects of firm performance, including productivity and financial returns, through its effect on skill development and coordination. We know little, however, about how specialization may influence a firm's R&D performance, including both R&D productivity and innovation impact. We propose that specialization is a double‐edged sword for R&D performance that can be influenced via changing scientists' collaborators: specialization increases scientist and firm R&D productivity but decreases the impact of innovations, while changing collaborators in a team reverses how specialization relates to productivity and impact. We validate this argument using a long panel (1970–2017) from the biotechnology industry. Specialization and collaborator change may thus serve as mechanisms to manage the trade‐off between productivity and impact in R&D activities. Managerial Summary This article studies how managers in firms may leverage their R&D workers' specialization to optimize their R&D performance. Our study shows that specialization is a double‐edged sword for R&D performance: it facilitates R&D productivity at the detriment of R&D impact, while the trade‐off shifts when collaborators within a scientist's team change. Thus, specialization and collaborator change condition R&D performance, with two implications for strategy. First, a firm's managers can recruit specialists or generalists depending on whether they want to prioritize productivity or impact in R&D activities. Second, job rotation practices that create periodic collaborator change may disrupt R&D productivity, yet invigorate explorative activity and increase the likelihood of impactful innovation.
