“…I specify the geography of biotechnology co-patenting by attributing each co-patent to the locations where the inventors reside. A co-patent with multiple inventors living in different cities is fractionally allocated, which is consistent with Maggioni et al [7], Ó hUallacháin and Lee [24], Lee [25], Ejermo and Karlsson [97]. If a co-patent was invented by three inventors residing in different cities, one-third of the co-patent is allotted to each city.…”

Knowledge creation involves social and collaborative processes with local and extra-local partners. The space of knowledge flows functions as a system of networks where knowledge is transmitted around different alignments of agents in distant places. Scholars argue that the concept of urban resilience combines local and extra-local competencies to develop an inter-city system, this is a major strategy for cities to mitigate and adapt to climate change and economic recession. Little attention has been given to the role of networks in co-invention and few empirical studies have been conducted. This article provides insights into the structure of inter-city networks of co-invention by examining the relative importance of the network compared with spatial proximity in biotechnology co-patenting across 150 American cities from 1983 to 2013. Results show that the U.S. inter-city structure gradually becomes more explicit, apparent, and identifiable in the network-based system. Network proximity better defines the biotechnology co-patenting relationships among the U.S. cities compared with spatial proximity. The current inter-city networks of co-invention are mostly regional, with some national but few local ties. This structure provides a way to develop mitigation and adaptation policies for climate disasters or economic recessions.

“…In consequence, the best-positioned actors in the network rapidly gain reputation because they are frequently cited, which contributes to their aura (Giuliani, 2013). Whenever identification of these leaders is easily obtained via observation or local broadcasting, the actors reduce their search costs and uncertainty by addressing them directly when establishing new collaborations (Ejermo and Karlsson, 2006). As a result, highly reputed actors may be considered more valuable and therefore more popular exchange partners (Ebbers and Wijnberg, 2010) because these relationships provide valuable resources and generate spillover effects by improving the status of the weaker companies (Podolny, 1993).…”

Purpose -The purpose of this paper is to explore the degree to which absorptive capacity and previous innovative performance affect network dynamics, specifically in the creation or destruction of inter-business relationships.Design/methodology/approach -The empirical study has drawn on the data collected in an industrial cluster located in the Valencian Community in Spain. This population of firms allowed us to test various roles played by network endogenous forces, absorptive capacity and former performance in the creation and dissolution of inter-organisational linkages. We followed an evolutionary approach and applied network analysis techniques.Findings -Empirical evidences suggest that absorptive capacity and previous innovative performance are predictors of inter-business relationships. Absorptive capacity affects the emergence of linkages in the technological network, due to the tacit nature of technological knowledge. On the other hand, previous innovative performance is an indicator to identify leaders companies. These companies tend to increase the reception of request for advice from local firms. Moreover, prestigious companies tend to be more selective in choosing collaborators.Practical implications -This study helps researchers and managers better understand network dynamics. The generation of inter-organisational relationships in clusters can be determined by cognitive proximity and prestigious status in the network. These evidences are relevant in a mature cluster where knowledge is asymmetrically distributed.Originality/value -Over the last few decades, studies on industrial clusters have evolved from the "canonical" standpoint. Nowadays, researchers usually take a more sophisticated and richer view of this reality, mainly as a consequence of the inclusion the proximity concept, intracluster heterogeneity and advanced analysis of overlapping between networks and territory. Thus, we try to add some empirical evidence along these lines.

“…Co-publications among regions have been analysed by Katz (1994) for the UK regions, Danell and Persson (2003) for Swedish regions, Liang and Zhu (2002) for Chinese regions, and Ponds et al (2007) for Dutch regions. Co-inventorships among Swedish regions using patent data have been analysed by Ejermo and Karlsson (2006). At the European level, we know of only one patent study by Maggioni and Uberti (2007) who analysed the effect of geographical distance on inter-regional collaborations based on co-inventorships between NUTS2 regions for six countries.…”

The geography of collaborative knowledge production in Europe

2008

We analyse inter-regional research collaboration as measured by scientific publications and patents with multiple addresses, covering 1316 NUTS3 regions in 29 European countries. The estimates of gravity equations show the effects of geographical and institutional distance on research collaboration. We also find evidence for the existence of elite structures between excellence regions and between capital regions. The results suggest that current EU science policy to stimulate research collaboration is legitimate, but doubt the compatibility between EU science policy and EU cohesion policy.
