Human capital investment has emerged as a critical determinant of long-term economic growth, particularly in the context of knowledge-driven and innovation-based economies. Sustainable Development Goal 8 (SDG 8) emphasizes sustained, inclusive, and sustainable economic growth, productive employment, and decent work for all. This paper examines the role of human capital investment—specifically education, skill development, health, and lifelong learning—in fostering long-term economic growth aligned with SDG 8. Drawing upon theoretical foundations, empirical evidence, and global policy frameworks, the study integrates human capital theory with the decent work agenda. The paper adopts a conceptual and analytical approach using secondary data from international organizations and prior empirical studies. Findings suggest that economies that prioritize inclusive and quality human capital investment experience higher productivity, employment quality, and resilience to economic shocks. However, challenges such as skill mismatches, inequality in access to education, and underinvestment in health hinder optimal outcomes. The paper concludes with policy implications for governments, educational institutions, and industry stakeholders, emphasizing the need for integrated human capital strategies to achieve sustainable and inclusive economic growth.
