This is a list some of technology centers throughout the world. Government planners and business networks often incorporate "silicon" or "valley" into place names to describe their own areas as a result of the success of Silicon Valley in California. Metrics may be applied to measure qualitative differences between these places, including:
How much and to what extent public and/or private research and development (R&D) funds are spent in the zones
What percentage of local employment is technology related
If the zone is mainly government funded or is mainly corporate driven (or is it a mix of both)
If mainly corporate, how much revenue and profit and which corporations have headquarters there
If mainly corporate, how much venture capital has been made available to companies in the zone
What supporting higher educational institutions (e.g., universities or colleges) are located nearby
