We can seek the answer from our own past experience. India has introduced many schemes and policies to develop clusters across industries. The schemes have been launched for promotion of both greenfield and existing clusters. However, the focus of the government has always been on new greenfield clusters. Governments, both at the Centre and states, have promoted SEZs, mega food parks, IT investment regions, mega leather clusters and the like. However, most of these clusters have fizzled out after the initial euphoria. For example, the government has thus far approved 30 mega food park projects, of which two projects, in Andhra Pradesh and Uttarakhand, are partially operational. Similarly, SEZs, which were lapped up eagerly by both the government and the private sector, have now lost their favour with developers and industries alike. Of the 588 SEZs approved since 2005, only 79 are operational (19 were already functional prior to the SEZ Act!). In fact, many developers are surrendering their approvals. The board of approval on SEZs has denotified 58 zones as of July 2013 and many more are in the offing.
