rKnowledge: The Spatial Diffusion of rDNA Methods

Maryann Feldman, Dieter Kogler () and Dabid Rigby

No 1311, Papers in Evolutionary Economic Geography (PEEG) from Utrecht University, Department of Human Geography and Spatial Planning, Group Economic Geography

Abstract: The 1980 patent granted to Stanley Cohen and Herbert Boyer for their development of rDNA technology played a critical role in the establishment of the modern biotechnology industry. From the birth of this general purpose technology in the San Francisco Bay area, rDNA-related knowledge diffused across sectors and regions of the U.S. economy. The local absorption and application of rDNA technology is tracked across metropolitan areas with USPTO patent data. The influence of cognitive, geographical and social proximity on the spatial diffusion of rDNA knowledge is explored using event history and panel models.
