Social networks across spatial agglomerations : the paradox of high-tech clusters. A critical revision of clusters

This paper analyzes a fundamental gap research in high-tech clusters surveying literature in a critical perspective: the paper evidenced the taken-for-granted assumption that knowledge spillovers (KS) are unique assets conveying flows of knowledge in clusters, arguing the importance of traded interactions based on market transaction conditions which occur in clusters, even beyond spatial social networks. In the case of high-tech clusters: which is the type of interactions occurring in clusters when there is a manifested lack of local social networks? Results suggest that under analytical (versus synthetic) knowledge base in clusters, the formal and traded commercial partnerships are also interactions (assets) available in clusters, beyond the traditionally claimed un-traded KS and not being restricted to spatial conditions but to global circuits of knowledge which complement the lack of local resources in high-tech clusters. High-tech clusters surveyed do not show the high levels of inter-firm collaboration that cluster theory predicts
