Digital Technology, Demographic Dividend, and Sustainable Economic Growth in Fiji

High population growth across developing Pacific countries has increased the share of young people, creating potential for a demographic dividend alongside accelerating digitalisation driven by technology transfer. This study empirically investigates the dynamic relationship between the demographic dividend, digitalisation (ICT access), and economic growth. An endogenous growth framework is employed and extended to incorporate demographic change and information technology adoption, along with education (human capital) and renewable energy use to capture the broader dimensions of sustainable economic growth. The results show that both the demographic dividend and ICT are positively associated with per capita income. Moreover, technology adoption and the demographic dividend exhibit a complementary relationship, implying that improvements in one reinforce the growth effects of the other, while education exerts a positive and statistically significant impact on economic growth. In contrast, renewable energy shows a positive but statistically insignificant effect, suggesting its role is emerging but important for long-term sustainability. In assessing the determinants of digitalisation, the findings indicate that demographic structure and urbanisation contribute positively; however, a substantial share of variation in digitalisation is explained by income levels and mobile phone technology. These results highlight the importance of policies that leverage demographic transition through education and digital technologies, and sustainable energy transitions to accelerate sustainable economic growth and improve welfare outcomes in Pacific developing economies.
