High Tech Specialization

Many cities around the United States have clusters of high tech industries, but this 2001 report, published by the Brookings Institution, shows that each of these clusters exhibits distinctive technological specializations.  The development and persistence of these specializations over time is indicative of the path-dependent character of the development of knowledge-based industry clusters, and is a critical factor in designing effective economic development policies.
