Abstract Firms may cooperate in R&D with various types of partners to boost their innovative performance. We model the optimal partnership portfolio breadth and empirically test the model on a panel of Dutch manufacturing firms. We confirm earlier evidence of a curvilinear relationship between breadth of R&D cooperation and a firm’s innovation performance. Two firm-specific factors, firm size and R&D-intensity, moderate this relationship. Small and low R&D-intensive firms tend to benefit more from embarking on R&D cooperation compared to large and/or R&D-intensive counterparts, but such benefits also tend to reduce more quickly when the number of types of cooperation partners increases.

技术合作组合和企业创新绩效：进一步的证据

摘要 企业可以与各种类型的合作伙伴进行研发合作，以提高其创新绩效。我们对最佳合作伙伴投资组合广度进行建模，并在一组荷兰制造公司上对模型进行实证测试。我们证实了较早的证据，即研发合作的广度与公司的创新绩效之间存在曲线关系。两个特定于公司的因素，公司规模和研发强度，缓和了这种关系。与大型和/或研发密集型同行相比，小型和低研发密集型企业往往从开展研发合作中受益更多，但随着合作伙伴类型数量的增加，这种收益也往往会更快地减少。
