Abstract

An analysis of railroad industry has been insufficient whereas there are lots of analysis of accumulation of technology, economic performances and ripple effects for macroscopic view and other industry of R&D investments. This study decided intellectual rights, patent, and paper as common indicators of scientific and technological performances for setting up performance targets through surveying and analysis of preceding study and verified a appropriateness of scientific and technological performances for railroad R&D 11 projects which were successfully finished. Preceding study has been set up performance targets by research investments as input, but this study made a performance target by model through a cross-sectional and residual analysis of performances of railroad R&D 11 Projects in applying research investments, capital investments and inner labor cost per man and research time as inputs, and verified a validity and a empirical analysis through analysis of other project.

R&D 투자로 인한 기술의 축적, 경제적 성과 및 파급효과에 대한 분석이 거시적인 측면과 타 부문에서는 다양하게 이루어지고 있으나 철도산업에 대한 분석은 미흡한 실정이다. 본 연구에서 성과목표 설정에 대해서는 선행연구에 대한 조사분석을 통하여 과학기술적 성과에 대한 공통지표로 지식재산권, 특허, 논문을 설정하고 성공적으로 종료된 철도 R&D 11개 사업의 과학기술적 성과에 대한 적정성을 검증하였다. 선행연구에서 투입요소로 투자금액에 의한 성과목표를 설정하였으나 정확도를 향상시키기 위해 투입요소로, 투자금액(RI), 자본적 투자금액(RCI), 인당 내부인건비(LCPM)를 적용하였으며 철도 R&D 11개 사업에 대한 횡단면 분석과 잔차 분석을 통하여 성과목표 모형을 설정하고 타 과제 분석을 통하여 실증분석과 타당성을 검증하였다.
