대·중소기업 간 생산파급효과 분석: 낙수효과와 분수효과의 실증분석을 중심으로

Social polarization in Korea has been intensified. A trickle-down and -up effects have been recently highlighted as solutions of social polarization. The trickle-down effect has been discussed before, while researches focusing on the trickle-up effect have been cited relatively low. Thus, this study shows that the production structure of industry is based on a close relationship among agents, and it is appropriate to look at the trickle-down and -up effects at the same time. For a comprehensive analysis of the trickle-down and -up effects, the scope of activity was limited to production, and the scope of producers was limited to large and SMEs (small and medium enterprises). In addition, the study analysed the path and scale of the ripple effect by separating production ripple effects into the direct effect and the cross(trickle-down and –up) effect. Furthermore, it examined how labour and capital, primary economic production factors, can impact on the direct effect and the cross(trickle-down and –up) effect. The results of this study show that the direct effects are significantly higher than the cross effect, which is divided into the trickle-down and -up effects, and that the linkage between large and SMEs has been gradually weakening. In addition, it cannot find the one-way effect that the economic ripple effect caused by production toward either one of the large and SMEs. It cannot be a realistic growth strategy for economy that one-sided growth and investment spread through other sides.
