정보화 지수 모형의 평가: 네트워크 준비지수(NRI)모형의 타당도 및 신뢰도를 중심으로

초록

The purposes of this study are to investigate the reliability and validity of the Network Readiness Index (NRI) and to make suggestions for improving the NRI. The reliability tests show that the Cronbach alpha coefficients of the three network readiness components are relatively high. The principal component factor analyses reveal that environment, readiness and usage have low convergent and discriminant validity. The overall results indicate that the NRI has serious problems on the validity. Furthermore, the results of higher order factor analyses (using structural equation modeling) indicate that the fit indices of the NRI model are low and suggest a bad fit to the data. Based on these findings, this study discusses some considerations to improve the NRI.
