Examining the nonlinear impact of human capital on environmental degradation in N-11 countries: an application of the PSTR approach.

The emergence of globalization and human capital has played a crucial role in the economic integration of countries, leading to the growth of the economies and a reduction in carbon dioxide (CO₂) emissions. This study highlights the importance of investing in human capital development to control ecological degradation and promote sustainable economic growth. This paper employs the PSTR method to investigate the threshold impact of GDP, globalization, information communication technology, and energy consumption on CO₂ emissions. The study examines two regimes, with a single threshold to analyze the transition of human capital on these variables. The results reveal that human capital developments play a central role in controlling ecological degradation due to reduced CO₂ emissions. Based on the empirical findings, this research study offers corresponding policy suggestions. [ABSTRACT FROM AUTHOR]
