Technological communities and the diffusion of knowledge

The external acquisition of technological knowledge is a central theme in research on technology management. In this paper it is argued that technological communities may provide a useful unit of analysis to study information and knowledge exchange among scientists and engineers working on a particular research agenda. Based on a worldwide survey of more than 700 individuals engaged in the research and development of neural network technology, the dynamics within that particular community are explored. The primary focus is to compare the characteristics of academic and industrial researchers, with special attention given to the timing of their entry into the field.
