Inter-temporal patterns of R&D collaboration and innovative performance

While prior studies have investigated the effect of collaborative RD with different partner types suppliers, customers, competitors and research institutions universities on firms innovative performance, the implications of dynamic patterns in these collaborations have not received attention. In a large panel of Spanish innovating firms operating in a broad range of industries during the period 2004-2011, we examine the differential effects of recently formed, persistent, and recently discontinued collaboration on innovative performance. Persistence is the most common pattern of collaboration, while discontinuities are most often observed for competitor collaboration. We find that it is persistent collaboration that has a systematically positive effect on performance. With the exception of recently formed collaboration with universities and research institutes, other temporal patterns of collaboration do not significantly improve performance. Implications of these findings are discussed.
