This book provides a comprehensive review of the evolution and performance of SEZs from a historical and comparative perspective by tracing the experiences of SEZs in 23 developing countries, including Korea, Taiwan, and China. Using a framework that integrates the basic tenets of theindustrial cluster approach with existing theories, it proposes a set of evaluation criteria for SEZs. Analysing quantitative data provided by the Ministry of Commerce and qualitative evidence based on field surveys conducted during 2004-9, the book assesses the economic contribution in the pre- and post-SEZ Act periods in India. Exploring the impact of SEZs on employment, trade, foreign exchangeearnings, government revenue, and technology transfers, it also examines evidence of social effects vis-a-vis land acquisition, human development, regional inequities, and environmental protection. Discussing the impact of internal dynamics and external forces on future prospects of SEZs, it offersconstructive suggestions to make policy investor-friendly and successful.
