경쟁과 기술혁신의 관계 : 첨단산업과 비첨단산업을 중심으로

The study about a relationship between competition and innovation has been a long controversy debate. The relationship between competition and innovation also has been developed academically from a opposition condition between the positive effect and the negative effect to the inverted U shape. In this study, we analyze the relationship between competition and innovation from the perspective of high technology industries and low technology industries by converting from firm-level data to industry-level data. The reason why we watch high technology industries and low technology industries is that they are directly-opposed technology opportunity and technology appropriability in terms of technology regime. After analyzing the linearity and non-linearity of each industry constellation as a linear equation and a quadratic equation, there is a U shape relationship between competition and innovation at the quadratic equation in the high technology industries. The reason is that a assumption of Aghion et al. (2005) which explains there is higher probability of turning up the levelled industry at the initial condition of competition is different from this study because South Korea’s condition of initial competition is showing unlevelled industry because of technology gap between large firms and SMEs. Therefore, Schumpeter effect happen first at the initial condition of competition. In addition to this result, there is a negative relationship between competition and innovation in low technology industry group that supporting Schumpeter hypothesis.
