Special Economic Zones Across the Globe
According to World Bank estimates, as of 2007 there are more than 3,000 projects taking place in SEZs in 120 countries worldwide. SEZs have been implemented using a variety of institutional structures across the world ranging from fully public (government operator, government developer, government regulator) to 'fully' private (private operator, private developer, public regulator). In many cases, public sector operators and developers act as quasi-government agencies in that they have a pseudo-corporate institutional structure and have budgetary autonomy. SEZs are often developed under a public-private partnership arrangement, in which the public sector provides some level of support (provision of off-site infrastructure, equity investment, soft loans, bond issues, etc) to enable a private sector developer to obtain a reasonable rate of return on the project (typically 10-20% depending on risk levels). Owing to the success of SEZ in China, various developing countries are trying to emulate the model for economic growth of the respective countries.
