Examines how clusters of industrial and technological innovation such as Silicon Valley get started.The contributors study how centers of industrial and technological innovation such as Silicon Valley get started. These clusters have many entrepreneurial high tech firms in a small area which give rise to rapid economic growth. No other analysts have studied systematically how such clusters start, though many earlier works have studied Silicon Valley in its mature phase. The contributors show that the key public and business policy elements of starting up a cluster are common across many regions, countries, and time periods.The contributors study how centers of industrial and technological innovation such as Silicon Valley get started.

No other analysts have examined how such clusters start, although many earlier works have studied Silicon Valley. The study's contributors conclude that the key public and business policy elements of starting a cluster are common to many regions, countries, and time periods.Preface; List of contributors; 1.
