Innovation networks and regional development - Evidence from the European Regional Innovation Survey (ERIS): Theoretical concepts, methodological approach, empirical basis and introduction to the theme issue

A general consensus exists in the debate on innovation-oriented regional de velopment, in which cooperation in innovation between manufacturing firms, service firms and research institutions continues to grow in importance wit h respect to business success and the economic performance of a region-at l east for some region types. The academic discussion, thus far, has been sha ped by a large number of outstanding theoretical studies focusing on this t opic from the perspective of the innovative milieu concept, the network the ory (spatial version), the regional innovation systems approach or the tran saction cost theory. Up to now, comparative empirical studies have not been performed evaluating the significance of innovation networks over a suffic iently large and statistically representative data set for the various type s of regions. This is the goal of this issue of European Planning Studies, which is introduced in this article. Briefly, the basic concepts for explai ning network-oriented regional development are described and the essential features of the European Regional Innovation Survey (ERIS) are presented-de veloped by a research team of German economic geographers and regional econ omists. Between 1995 and 1999 ERIS carried out three extensive surveys in I I European regions with a total return of 8635 questionnaires, in an effort to identify systematize, and quantify linkages between innovative players. The question of the range of such innovative linkages plays a central role in this analysis.
