National Investment & Manufacturing Zones (NIMZs) are one of the important instruments of National Manufacturing Policy, 2011. NIMZs are envisaged as large areas of developed land with the requisite eco-system for promoting world class manufacturing activity. So far, three NIMZs namely Prakasam (Andhra Pradesh), Sangareddy (Telangana) and Kalinganagar (Odisha) have been accorded final approval and 13 NIMZs have been accorded in-principle approval. Besides these, eight Investment Regions along the Delhi Mumbai Industrial Corridor (DMIC) project have also been declared as NIMZs.
The main objective of Special Economic Zones is promotion of exports, while NIMZs are based on the principle of industrial growth in partnership with States and focuses on manufacturing growth and employment generation. NIMZs are different from SEZs in terms of size, level of infrastructure planning, governance structures related to regulatory procedures, and exit policies.
