Interindustry Knowledge Transfer and Absorption via Two Channels: The Case of Korea

Won-Sik Hwang and Jeong-Dong Lee ()

Global Economic Review, 2014, vol. 43, issue 2, 131-152

Abstract: This paper investigates interindustry knowledge spillovers using input-output (IO) data and patent information, since spillovers can arise from different types of sources and linkages. Economic transactions of intermediate goods are used to track embodied knowledge flows with the data derived from Korean IO tables. In terms of disembodied knowledge flows, a technology proximity matrix is constructed using patent information. The empirical results show that patterns of interdependences among industries are different and this implies that policy-makers should take into account the interdependences between industries even when planning industry-specific policies. Moreover, excessive concentration of R&D investment needs to be improved.
