It is primarily understood that clusters are the sources of innovation and therefore, of late, the focus of researchers and practitioners has been increasingly to ascertain the factors driving innovation among the firms in a cluster, especially in a high-tech cluster. Researchers have identified that the dynamism of a firm in terms of degree of interactions of a firm with other firms and related institutions as one of the key drivers of innovations in a firm residing in a cluster. However, this has not been empirically validated considering the gamut of interactions of a firm with all the stakeholders within and outside a cluster. It is in the context of Bengaluru (erstwhile Bangalore) cluster which houses densely interconnected network of high-tech manufacturing firms this paper probes the influence of degree of cluster linkages on the firm-level innovation.
