직무분석을 활용한 직무중심 인사관리와 고령화가 기업 성과에 미치는 영향

초록

This paper explores the effects of Job-based HR and ageing, as well as their interaction, on firm performance using the 2011 Workplace Panel Survey(WPS) of the Korea Labor Institute. The results show that Job-based HR measured by the usage of job analysis has a positive effect on labor productivity(sales per employee), but ageing measured by the ratio of employees over 45 years old has a negative effect on productivity. The firm which heavily uses job analysis has 2.38 million won higher sales per employee compared to the firm which doesn't use job analysis at all when other conditions are equal. On the other hand, when the firm's ageing increases by 1%, the sales per employee decreases 1.34 million won when other conditions are equal. Additionally, Job-based HR has positive effects on productivity for the firms with both high and low proportion of older employees, but the positive impact of Job-based HR is significantly stronger at the firm with high proportion of older employees. Therefore, the results of this study suggest that Korean firms of which older employees have heavily increased need to introduce Job-based HR immediately.
