The economic fitness of a country shows its capacity to address complex issues, such as climate change and environmental degradation, which are urgent global concerns. Its key function is given less importance in empirical research and has been neglected by existing empirical studies. Concerning this neglect, our study investigates the influence of economic fitness on CO emissions in the context of the environmental Kuznets curve (EKC) for the BRICS nations between 1995 and 2015. The Feasible Generalized Least Squares (FGLS) and Panel-Corrected Standard Error (PCSE) techniques are used to estimate the empirical association. The results suggest that economic fitness and CO emissions have an inverted N-shaped relationship. Furthermore, after accounting for major contributing factor of CO emissions like GDP per capita, financial development, urbanization, and foreign direct investment, our robustness checks produce robust and significant results.
国家的经济适应性表现出其解决复杂问题的能力，如气候变化和环境恶化等全球紧迫问题。在实证研究中，其关键功能的重要性较低，并且已被现有实证研究所忽视。针对这种忽视，我们的研究调查了经济适应性对金砖国家 1995 年至 2015 年间环境库兹涅茨曲线（EKC）中 CO 排放的影响。我们使用可行广义最小二乘法（FGLS）和面板校正标准误差（PCSE）技术来估计经验关联。结果表明，经济适应性和 CO 排放之间呈倒 N 形关系。此外，在考虑人均 GDP、金融发展、城市化和外国直接投资等 CO 排放的主要影响因素后，我们的稳健性检验得出了稳健且显著的结果。
