Cluster development aims to enhance the productivity and competitiveness of small and medium enterprises through economies of scale. India has over 350,000 small enterprises clustered in sectors like textiles, metals, food processing and others. Clusters provide opportunities for mutual learning, knowledge sharing and access to common facilities. However, clusters require state intervention for long-term sustainability since benefits may not be immediately visible. The Ministry of Small Scale Industries initiates various programs to promote technology upgrades, access to finance, skills and market linkages for clusters across India.
