Increased global sourcing and reorganization in high value-added-centered industries make parts and material industry, which forms 46% of total production and 40% of total exports in manufacturing sector, more important. In a sense that parts and material industry is . vulnerable in spite of its consequence, a lot of policy support was given. Parts and material industry, however, has never been researched empirically in firm level, therefore in this research we would like to analyze the competitiveness of parts and material firms compared with manufacturing sector, and to inquire into their current R&D position. Consequently, we suggest how to make value-added products more efficiently through R&D.

Information and communication technology (ICT) has been recognized as one of the alternative source of productivity growth and, in turn, economic growth. However, there has not been much literature reporting that the benefit of ICT has materialized in countries other than United States. Since the Korean economy has allocated a large amount of resource to develop ICT capacity after the mid 1990s, it is time to investigate whether the invested resource has done something to boost the productivity. This study performs various regressions to analyze the relationship between ICT and productivity at the sectoral level. The basic methodology relies upon the framework developed by Griliches in the field of R&D. The study also examine the causality among ICT, R&D and industrial productivity based on the time-series analysis. The empirical results show that the ICT has not provided much positive effect in productivity improvement so far, and more attention should be paid to the efficient utilization of invested capital.
