Abstract
This paper studies the effect of inter-firm R&D network ties on the technological performance of companies in high-tech industries. Tie strength is analysed through a multidimensional perspective. We find that strong ties in terms of the dimensions time and depth, measured by length and multitude of partnerships, degree of cooperation and similarity of ties, do indeed improve technological performance. However, our findings on cultural closeness support a weak ties perspective. Our research suggests that a combination of stronger and weaker R&D ties, with elements of both social embeddedness and international diversity, is most beneficial for the technological performance of companies.
