Mobility of Research Workers and Knowledge Diffusion as Evidenced in Patent Data The Case of Liquid Crystal Display Technoloy
Michael Stolpe
Abstract: This paper analyses the nature of knowledge spillovers
from research and development (R&D) in the field of liquid crystal display
technology by estimating the impact of inventors changing organizational
and collaborative affiliations on the probability of citations in US
patents filed between 19761995, while controlling for geographic
localization effects. It is argued that technology policy towards a
particular industry must take the role of inventors mobility in
facilitating the flow of ideas across space and innovating organizations
into account. Policy implications for the display industry are discussed
against the background of previous experiences with government-sponsored
R&D collaborations.
