본 연구는 스마트공장 도입의 효과와 관련 요인을 분석하였다. 이를 위해 도입기업과 비도입기업의 표본 데이터를 median-size-industry matching method로 각각 110개, 325개를 수집했다. 도입 전년부터 도입 후 4년도까지 재무제표 데이터(ROA 등)를 활용했는데 event study method에 따른 abnormal operating performance, annual abnormal changes를 구한 뒤 Wilcoxon signed-rank test와 t-test로 분석했다. ROA와 매출증가율은 도입 후 단기적인 효과가 나타났으나 장기적으로 이어지지는 않았다. 또한 도입효과에 인력비중, 연구개발 수준, 이전 재무 성과 세 가지 요인이 조절효과로 영향이 있는지 회귀분석을 한 결과 연구개발 수준과 이전 재무 성과의 조절효과를 확인했다. 도입 효과에 도입시기의 영향과 이와 관련된 요인으로 이전 재무 성과와 기업규모의 조절효과가 있는지 회귀분석을 한 결과 장기에 도입시기가 늦을수록 도입효과가 더 커졌고, 이전 재무 성과와 기업규모의 조절효과를 확인했다.

Abstract ▼ AI-Helper

We analyze the effects and related factors of Smart Factory adoption. 110 and 325 samples were collected by median-size-industry matching method, respectively, of adopting and non-adopting companies. We use financial statement data (ROA, etc.) from the year before adoption to the fourth year after adoption. Abnormal operating performance and annual abnormal changes are obtained according to event study method, and analyzed by Wilcoxon signed-rank test and t-test. ROA and sales growth rate demonstrate short-term effects after adoption, but not long-term effects. As a result of regression analysis to examine if the three factors of labor intensity, R&D intensity, and prior financial performance have moderating effect, the moderating effect of R&D intensity and prior financial performance is confirmed. In addition, we perform regression analysis to confirm performance effects of early and late adoptions and whether prior financial performance and organization size have moderating effect. It is confirmed that the later the time of adoption, the greater the effect of adoption in the long term and the moderating effect of prior financial performance and organization size is confirmed.
