Abstract
To enhance country competitiveness, we can improve the function of national innovation system and the exercise of policy instruments for S&T indexes. Despite the great importance to national development, scholars have paid little attention to this policy agenda, in particular the understanding of the linkages of national systems, policy instruments and S&T indexes. In this study using data from WEF and IMD, we draw on the questionnaire survey and Fuzzy Delphi methods to explore such linkages in Taiwan. We identify the missing linkages in Taiwan's national innovation systems, based upon which policy implications are drawn out.
