Clusters are important drivers of regional economic growth. Although their benefits are well recognized, research into their evolution is still ongoing. Most real-world clusters seem to have emerged spontaneously without deliberate policy interventions, each cluster having its own evolutionary path. Since there is a significant gap in our understanding of the forces driving their evolution, this study uses a quantitative approach to investigate the role of inventor collaboration networks in it. Inventor collaboration networks for 30 top-performing American metropolitan clusters were constructed on the basis of patent co-authorship data. The selected clusters operate in hi-tech fields: information technology, communications equipment and the biopharmaceutical industry. Starting from a widely accepted hypothesis that the 'small-world' structure is an optimal one for knowledge spillovers and promotes innovation effectively, the authors statistically tested the impact of 'small-world'network properties on cluster innovation performance proxied by patent output. The results suggest that the effect of the small-world structure is not as significant as theorists hypothesized, not all clusters benefit from the presence of inventor collaboration networks, and cluster performance can be affected by policy interventions. Our analyses also suggest that cluster typology moderates the impact of inventor network properties on cluster innovation performance.

“…degree distribution and clustering coefficients), and these features were studied to understand the behaviour of social networks. For instance analysing degree distribution and clustering coefficients can identify regions where innovations occurred and thus find ways to accelerate development of innovations (Fleming et al, 2011). Thus understanding social network properties and network behaviour may help people to design such networks more effectively and efficiently.…”

Purpose -Most studies on tie strength have focused on its definition, calculation and applications, but have not paid much attention to how tie strength can help analyse online social networks. Because ties play different roles in a network depending on their strength, the purpose of this paper is to explore the relationship between tie strength and network behaviours. Design/methodology/approach -The authors propose a simple metric for tie strength measurement and then apply it to an online social network extracted from a blog network. These networks are massive in size and have technology for efficient data collection, thereby presenting the possibility of measuring tie strength objectively. From the results several key social network properties are studied to see how tie strength may be used as a metric to explain certain characteristics in social networks. Findings -The online networks exhibit all the structural properties of an actual social network, not only in following the power law but also with regard to the distribution of tie strength. The authors noted a strong association between tie strength and reciprocity, and tie strength and transitivity in online social networks. Originality/value -This paper highlights the importance of analysing online social networks from a tie strength perspective. The results have important implications for the development of efficient search mechanisms and appropriate group leaders in virtual communities.

“…Knowledge is assumed to flow between people who know each other from joint research projects rather than between the innovators. Therefore, it is common to link the inventors of patents directly (Balconi et al, 2004;Fleming et al, 2004Fleming et al, , 2006Singh, 2005), but these connections can also be used to identify channels of knowledge transmission between the innovators in linking them via common inventors (Breschi and Lissoni, 2003;Cantner and Graf, 2006;Graf and Henning, 2006). While the function of a gatekeeper could in principle be served by individuals as well as by organisations, we find it more appropriate to pursue the latter approach and study organisations as they are are less mobile than individuals and are therefore more easily identified as local or external actors.…”

Gatekeepers in regional networks of innovators

The internal density of a local network is said to increase the regionspecific knowledge-stock and might lead to a comparative advantage. However, it might also lead to a lock-in situation, if local trajectories are directed towards inferior solutions. Accordingly it is argued that successful clusters are characterised by the existence of gatekeepers, i.e. actors that generate novelty by drawing on local and external knowledge. We attempt to answer questions related to the role and characteristics of gatekeepers within regional innovation systems by applying social network analysis based on patent data for four East-German regions. The regional networks appear to be significantly different with respect to the overall degree of interaction and with respect to their relative outward orientation. Concerning the characteristics of gatekeepers, we find that size does not play the major role for being a gatekeeper. It is rather absorptive capacity that matters for gatekeepers. It also shows that public research organisations serve the functions of a gatekeeper to a higher degree than private actors.
