A Cluster is neither a sector nor an industry. It is a geographical concentration of interconnected companies, specialized suppliers, and service providers, businesses in related industries, and associated public agencies and institutions.
By their nature of being closely located, clusters are considered to increase the productivity with which companies can compete, and encourage innovation, and the stimulation of new business.
It is based on a triple helix innovation model, which is led by business, supported by public agencies and donors, and underpinned by academia.
