The Human Development–Sustainable Development Nexus: Global Evidence and Policy Implications

Abstract

Human development and sustainable development are closely interconnected, yet the relative contributions of human development components to the achievement of the Sustainable Development Goals (SDGs) remain insufficiently quantified. This study examines the empirical relationship between human development and sustainable development outcomes, with particular attention to education and innovation capacity. Using a global panel dataset covering 167 countries from 2015 to 2022, we analyse how the Human Development Index (HDI) and its core components influence overall SDG performance and selected goal-specific outcomes. Employing panel regression techniques with pooled, fixed-effects, and random-effects estimators, the results reveal a strong and robust positive association between human development and SDG achievement. Improvements in the HDI are consistently associated with higher SDG Index scores, both across and within countries over time. Disaggregated analysis shows that education-related variables, mean years of schooling and expected years of schooling exert the strongest and most immediate impact on sustainable development outcomes, while short-term variations in health indicators play a more limited role. Innovation-related outcomes are particularly sensitive to accumulated human capital, highlighting the importance of long-term investment in education for knowledge-based development. Additional convergence analysis indicates that countries with lower initial SDG performance tend to experience faster progress, suggesting meaningful catch-up potential when human development improves. Overall, the findings confirm that human development, particularly education, is a foundational driver of sustainable development and provide critical policy insights for countries seeking to strengthen sustainability outcomes and competitiveness in education- and innovation-driven sectors.
