Exploring the Synergistic Impact of Healthcare and Education Investments on Sustainable Economic Development: A Study...

Investments in public health and education are usually examined independently, but in developing countries, both are relevant to Sustainable Economic Development (SED). Within an integrated policy framework, this study aims to examine the complementary relationship between investments in health and education and their relationship with SED. A mixed-method approach was employed, consisting of 465 questionnaire responses from participants, including government officials, and 96 semi-structured interviews. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), quantitative data were analyzed, and to contextualize the statistical results, qualitative findings were involved. Results indicate that healthcare infrastructure, coupled with investment in health and education, communicable disease reduction, mental health services, and coordinated public investment, is positively and statistically related to SED. Explained variance is (R² = 0.100), showing that there is a moderate but meaningful contribution in the broader institution context. Findings contribute to existing literature by incorporating cross-sectoral modeling with qualitative institutional-level findings. It provides a more holistic understanding of the relation between coordinated human capital investments and developmental outcomes. These insights recommend integrating policies between the health and education sectors to support inclusive and sustainable development in low- and middle-income countries.
