This paper examines how Korean technological development is linked with scientific activities and spreads to industrial fields
through knowledge flows. It empirically assesses the linkages between scientific and technological knowledge flows and technological
innovation by determining whether the quantity and quality of scientific papers cited by, and the knowledge being absorbed
in, Korean patents filed in USPTO varied over time, and between technology fields. We conducted MANOVA and then canonical
discriminate analysis. Our findings are: the patterns of both the absorption of scientific knowledge and the diffusion of
technological knowledge differ by period and by field, and the speed of knowledge diffusion differs by technology field. This
implies that the time required for Korean investment in basic and applied research to impact her industrial innovation differs
by technology field.
