자동화기술과 생산기능 직무의 지적숙련 요건

This study carries out an empirical analysis of how various aspects of automated technology such as the level of automation, the level of performing operating and setting tasks, the frequency of changes in products, and the frequency of breakdown affects intellectual skills requirement of manufacturing production jobs, utilizing a worker survey data collected in association with Workplace Panel Data by Korea Labor Institute. The regression models are OLS whose dependent variables are basic cognitive skills and uncertainty-coping intellectual skills.
The results of this study indicate the following. First, semi-automation has a significantly positive effect on intellectual skills requirement, and full automation has a weakly positive one. Mechanization of manual works and semi-automation of manual machines have significantly positive effects, while full automation does not. Second, the level of operating and setting tasks has a significantly effect with inverted U-shapes on intellectual skills requirement. As compared to none-automation works, it has a significantly positive effect, while supporting tasks does not. Third, the high frequency of change in product has a significantly positive effect on intellectual skills requirement, while the moderate one has a weakly effect. Fourth, the high and the moderate frequency of breakdown have significantly positive effects on intellectual skills requirement, As compared to none-automation works, the low frequency does not have a significant effect. Finally the empirical results are outlined and their implications are discussed.
