User cooperation effects on firm's innovation outputs

We analyzed the effects of R&D cooperation with users and the intensity/continuity of such cooperation on firms' innovation output—whether radical or incremental. We also examined the moderating effect of firm size on these relationships. Results show that cooperation with users favours the development of both radical and incremental product innovations. In addition, we found that the higher the intensity/continuity of the relationship with users, the more likely radical innovations are to develop when compared with incremental innovations. We note that the positive effect of cooperation on the development of innovation is especially significant for small firms. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.
