为了减缓气候变化，许多研究已经进行，以确定二氧化碳排放的决定因素。然而，在这个问题上还没有达成共识，因为过去的工作往往没有考虑到未观察到的个体异质性。因此，本研究通过采用面板分位数回归，将可再生能源消费和技术创新的影响纳入1980-2014年全球30个国家的研究背景中，重新审视环境-能源-增长关系。该方法的优势在于考虑了区域分布的异质性，能够详细描述不同排放水平下CO2排放与驱动因子之间的联系。结果表明，各影响因素对CO2排放的影响具有异质性。对于高排放国家而言，由于可再生能源使用比例较小，可再生能源消费在减少CO2排放方面的作用有限。此外，技术创新对二氧化碳排放量相对较高的国家影响很大。因此，一种选择是在财政上支持和应用技术创新，以较低的成本生产可再生能源，并提高能源效率。此外，转变经济增长方式有助于从不可再生能源转向可再生能源，以满足能源需求。
To mitigate climate change, many studies have been conducted to identify the determinants of CO2emissions. However, a consensus has not been reached yet on the issue because past work has often not considered the unobserved individual heterogeneity across countries. Therefore, this study revisits the environment-energy-growth nexus by employing a panel quantile regression to incorporate the effects of renewable energy consumption and technological innovation within the research background of global 30 countries over the period 1980–2014. The advantage of this method is considering the distributional heterogeneity to provide a detailed description of linkage between the CO2emissions and driving factors at different emissions levels. The results show that the effects of determinants on CO2emissions are heterogeneous. For high-emissions countries, the function of renewable energy consumption is limited in reducing CO2emissions due to the smaller proportion of renewable energy use. Moreover, technological innovation greatly affects countries with relatively higher CO2emissions. Therefore, one option is to financially support and apply technological innovations to generate renewable energy at lower costs as well as increase energy efficiency. Moreover, transforming the economic growth mode is helpful to transfer from non-renewable to renewable sources of energy to meet energy demand.
