Abstract
This study empirically investigates the export structure change of OECD countries in the field of information technology from 1995 to 2005. We used Between and Within Entropy index to estimate the difference of export structure change rather than RCA index(simple export structure change). In addition, we also estimate the relationship between R&D activities and export difference. First, empirical findings showed that IT export market concentration is decreasing gradually, and changing to more competitive market structure. Second, compared to other OECD countries, Korean exports weight of information and communication industry can be seen higher than that of bio-industry. Third, Entropy index was increased from 1995 and then gradually decreased as the starting point of 2000. Finally, the relationship between R & D activities in the telecommunications industry and impact of the export structure changes was a positive.
