Query: A global snapshot

For people who want to get an overview of global clusters, what they are, what they can do to a nation's innovation system and its economy, what they have in common and how they differ in these global regions.It is easy reading and gives a good global perspective. It highlights the local traits and permits comparisons with other geographical clusters, although it does not go as indepth one may hope for further academic research. Given the interview based research style, however, it keeps it lively and is not as "dry" as many other academics books.The book makes clear that Silicon Valley and Boston's Route 128 are no longer the only innovation clusters.Dr. Martin Haemmig / SwitzerlandAdj.
