Why are specific places so often the nexus for new inventions? For instance San Jose, California well outpaces other U.S. cities in absolute and even relative numbers of patents. This presentation uses ideas from the geography of technology to better understand technology emergence. Features of the physical, social and institutional environment provide strong clues. Nonetheless strongly innovative regions rarely persist over time. And other technologies, including general purpose technologies, lack any strongly regional focus at all. These elements of geography and emergence present both a challenge and opportunity for measuring emergent technologies using science and technology indicators.
