Abstract

National Innovative Capability (NIC) is an important decisive factor where economic growth is concerned. As such, it is very important to measure and manage NIC. The composite index approach is one of the widely used approaches to measuring NIC, but there have been insufficient reviews of its feasibility and reliability. This paper conducted an analysis of the feasibility and reliability of the report on the last three years (i.e. 2011 through 2013) of the Innovation Union Scoreboard (IUS) of the EU, which is the most representative means of measuring NIC. It turned out that its reliability meets the recommended criteria as a result of Chronbach's alpha-based test of the models of IUS-related composite index. However, neither the absolute fit index nor the incremental fit index was found to meet the recommended criteria in a construct validity analysis. It also turned out that predictive validity is very low as a result of panel linear regression analysis of sectors and items of IUS-related composite index. This paper presents a number of considerations to be made when measuring national innovative capability using the composite index approach, as well as major policy suggestions based on the results of the analysis.

국가혁신역량은 경제성장의 중요한 결정요인으로 이에 대한 측정과 관리는 매우 중요하다. 국가혁신역량을 측정하는 다양한 접근방법 중 복합지표 접근법이 널리 활용되고 있지만, 그 타당성과 신뢰성에 대한 검토는 부족한 실정이다. 따라서 국가혁신역량을 측정하는 가장 대표적인 유럽연합 IUS(Innovation Union Scoreboard)의 최근 3개년 보고서('11년~'13년)를 중심으로 신뢰성과 타당성을 분석하였다. 분석결과 IUS 복합지표 측정모형의 크롬바흐(Chronbach's) ${\alpha}$ 검정 결과 신뢰도는 권고기준을 충족하였다. 하지만 구성타당도와 예측타당도를 분석한 결과, 구성타당도에서는 절대적합지수와 증분적합지수 모두 권고기준을 충족하지 못하였다. 또한 IUS 복합지표의 각 부문과 항목에 대한 패널선형회귀분석 결과, 예측타당도가 매우 낮게 나타났다. 이러한 분석결과를 토대로 복합지표 접근법으로 국가혁신역량을 측정할 때 고려사항과 주요 시사점을 제시하였다.
