# 17.15 Co-inventor Networks and Knowledge Production in Specialized and Diversified Cities

Why do some cities produce more knowledge than others? The standard explanation rests upon the social networks that connect economic actors, within and between cities, and that structure the quantity and the quality of interactions from which new ideas are generated. These interactions are increasingly understood as shaped by different forms of proximity that congeal, at different times in different places, in complex assemblies that give rise to different forms of competitive advantage. Recent research focusing on the U.S. urban system has shown that metropolitan regions characterized by more extensive local and non-local network ties outperform cities where economic agents are isolated. However, across most of this work, little attention is given to the character of the local knowledge base and whether that is related to the structure of co-inventor networks. In this paper, we show that the social networks linking co-inventors differ between cities that produce specialized knowledge and those that produce diversified knowledge. These ideas are extended in models of tie-formation that show inventors in specialized cities value spatial proximity less and cognitive proximity more than inventors in diversified cities as they partner with collaborators from other urban areas.

# 16.09 Not too close, not too far: testing the Goldilocks principle of ‘optimal’ distance in innovation networks

This paper analyses how the formation of collaboration networks affects firm-level innovation by applying the ‘Goldilocks principle’. The ‘Goldilocks principle’ of optimal distance in innovation networks postulates that the best firm-level innovation results are achieved when the partners involved in the network are located at the ‘right’ distance, i.e. ‘not too close and not too far’ from one another, across non-geographical proximity dimensions. This principle is tested on a survey of 542 Norwegian firms conducted in 2013, containing information about firm-level innovation activities and key innovation partners. The results of the ordinal logit regression analysis substantiate the Goldilocks principle, as the most innovative firms are found amongst those that collaborate with partners at medium levels of proximity for all non-geographical dimensions. The analysis also underscores the importance of the presence of a substitution-innovation mechanism, with geographical distance problems being compensated by proximity in other dimensions as a driver of innovation, whilst there is no support for a potential overlap-innovation mechanism.

# 13.24 Do inventors talk to strangers? On proximity and collaborative knowledge creation

This paper investigates how physical, organisational, institutional, cognitive, social, and ethnic proximities between inventors shape their collaboration decisions. Using a new panel of UK inventors and a novel identification strategy, this paper systematically explores the net effects of all these ‘proximities’ on co-patenting.  The regression analysis allows us to identify the full effects of each proximity, both on choice of collaborator and on the underlying decision to collaborate. The results show that physical proximity is an important influence on collaboration, but is mediated by organisational and ethnic factors. Over time, physical proximity increases in salience. For multiple inventors, geographic proximity is, however, much less important than organisational, social, and ethnic links. For inventors as a whole, proximities are fundamentally complementary, while for multiple inventors they are substitutes.

#10.11 An investigation of the relation between cooperation and the innovative success of German regions

Concepts like regional innovation systems, innovative milieu, and learning regions emphasize the positive contribution of intra-regional cooperation to firms’ innovation performance. Despite substantial numbers of case studies, the quantitative empirical evidence for this claim is thin. Using data on the co-application and co-invention of patents for 270 German labor market regions the study shows that intra-regional cooperation intensity and regional innovation efficiency are associated. In contrast to the negative influence of inter-regional cooperation, medium levels of intra-regional cooperation stimulate regional innovation efficiency.
