This study examines the global growth competitiveness of countries using the dynamics of growth, ICT, and innovation. It also introduces a new dynamic, cybersecurity, and argues that within a growth competitiveness framework, ICT, innovation, and cybersecurity mechanisms allow some countries to achieve higher ranks on the competitiveness ladder than others. Based on a theoretical framework that encompasses the economic growth model, the complementarity theory, and the international law theory, a model that integrates ICT, innovation, and cybersecurity, depicts the relationships amongst them and with growth competitiveness, and incorporates complementary factors with possible moderating effect is presented. The model proposed relationships are then tested using PLS-PM. The model proves to have adequate goodness-of-fit as well as predictive validity. Results support most hypotheses showing: (1) a positive relationship between ICT and innovation; (2) a positive relationship between each of innovation and ICT with growth competitiveness; (3) a mediating effect of innovation has in the ICT – growth competitiveness relationship; (4) a positive relationship between ICT and innovation on one hand and cybersecurity on the other; (5) a mediating role of cybersecurity in the ICT – growth as well as the innovation – growth relationships; and the (6) moderating effect that human capital has in the above relationships. Cyber threats, however, do not have a moderator role in these relationships. These findings are interpreted in relation to the extant body of knowledge related to ICT, innovation, and cybersecurity. Moreover, the theoretical and the practical implications are discussed and the practical significance is shown. Finally, the study limitations are listed, the recommendations are presented, and the direction for future work is discussed.
