Special economic zones are geographical regions that have more liberal economic laws than a country's typical laws. They are intended to be engines of economic growth. India's SEZ policy aims to enhance foreign investment, promote exports, and create opportunities for domestic businesses. As of 2007, India had over 200 functional SEZs. West Bengal passed a SEZ law in 2003 to accelerate economic reforms. SEZs in West Bengal have grown industries like jewelry production and provided employment opportunities, but they also face issues like criticisms of land acquisition practices.
