Abstract
Intellectual capital, through strengthening human capital, structural capital, and relational capital, can lay the groundwork for innovation, enhance resource productivity, and drive the development of clean technologies; however, its effectiveness is also contingent upon the institutional conditions of countries. Hence, the present study aims to investigate the impact of national intellectual capital on green economic growth and the moderating role of institutional quality in selected BRICS+ countries over the period 2000–2025. In this research, national intellectual capital is measured using three components—human capital, structural capital, and relational capital—and the Principal Component Analysis (PCA) method. Additionally, financial development, trade openness, government expenditure on education, renewable energy consumption, and foreign direct investment are considered control variables. Following an examination of the data characteristics, the model is estimated using the robust regression method. The results indicate that both national intellectual capital and institutional quality have a significant positive effect on green economic growth at the 5% significance level. In contrast, the interaction effect of national intellectual capital and institutional quality is negative and statistically significant at the 5% level. Thus, under the investigated circumstances, institutional quality does not necessarily strengthen the effect of intellectual capital on green economic growth. Furthermore, at the 5% significance level, financial development, trade openness, government expenditure on education, and renewable energy consumption exert significant positive impacts on green economic growth, whereas the effects of foreign direct investment are not statistically significant
