Special Economic Zones (SEZs) are specifically delineated duty-free enclaves deemed to be foreign territory for trade purposes. They aim to provide a competitive environment for exports by offering tax exemptions, subsidies, and relaxed regulations. SEZs started in the 1960s and have expanded over the years. Currently there are over 150 approved SEZs in India focused on sectors like IT, pharmaceuticals, and textiles. SEZs generate economic activity and promote investment but also face criticism around loss of government revenue, land acquisition issues, lack of infrastructure planning, and potential exploitation of labor. Oversight and an exit policy for developers are suggested to address some of these concerns.
