혁신적 ICT 산업에 있어 한일기업 간 협력의 새로운 모델 연구 - ICT 산업에서 NTT in Japan과 CMI in Korea 간의 협력 사례 연구 -

초록

We investigate to what extent productivity of large firms is influenced by productivity growth of small and medium-sized enterprises(SMEs). Our main findings from the analysis of Granger causality, cointegration and error-correction model are as follows. First, we cannot reject that SME labour productivity increases Granger causes labour productivity increases of large firms both in Korea and in Japan. Second, we find evidence for a positive effect of SME labour productivity increases on labour productivity increases of large firms not only in the long-run but also in the short-run both in Korea and Japan. This empirical findings is judged to be from the fact that Korea has benchmarked Japanese industrial development in the form of cooperative relation between large firms and SME. However, we have note that the productivity gap between large firms and SME in Japan decreased rapidly compared to Korea due to the cumulative effort of Japanese policy authority and industrial sectors to increase economic efficiency.
