Types of innovation and inter-firm co-operation

The paper presents the results of an empirical study that aims to investigate the impact of interfirm co-operation over innovation on four different types of innovation: product, process, incremental and radical innovation. Drawing on the innovative milieu literature, the impact on the above four types of innovation was tested for both external and internal factors of innovation such as inter-firm co-operation over innovation, production networking, as well as R&D investment and R&D personnel. Four probit models were run by using a unique data set compiled as part of the Regional Innovation Strategy for the West Midlands (UK) Project. The main findings of the paper seem to provide substantial evidence that, for any of the four types of innovation considered, firms' capacity to innovate could greatly improve if they co-operated with other firms over innovation in addition to or instead of investing in R&D. Innovation policy should not overlook, therefore, the systemic component of innovation and ought to attempt to initiate and support inter-firm co-operation. This would mean a renewed and more focused analysis of firms' clusters as part of a multi-faceted approach to innovation policy.
