This study examines the functional relationship between non-renewable energy (NRE) and life expectancy in four selected oil-producing African countries (Algeria, Egypt, Libya and Nigeria) from 1990 to 2017. The role of income level and institutional quality (captured by control of corruption and regulatory quality) is evaluated to ascertaining the moderating or exacerbating effects of NRE (measured by natural gas, fuel and coal) on life expectancy. The empirical analyses are anchored on a set of preliminary tests consisting of cross-sectional dependence test, panel unit root tests and co-integration test, respectively. In the final analysis, the fully modified OLS panel method is engaged for model estimation. The empirical results reveal the negative effect of NRE on life expectancy both in models. Besides, the positive effects of income level are helpful in subduing the negative impacts of NRE on life expectancy while that of institutional quality further exacerbates it. The impacts of renewable energy and carbon emissions on life expectancy are recorded in a reverse direction. Relevant policy implications are advanced in the light of these emanating outcomes.

收入水平和制度质量在不可再生能源消费和预期寿命关系中的作用：来自非洲选定石油生产经济体的证据

本研究考察了 1990 年至 2017 年四个选定的非洲产油国（阿尔及利亚、埃及、利比亚和尼日利亚）的不可再生能源 (NRE) 与预期寿命之间的功能关系。收入水平和制度质量的作用（由腐败和监管质量的控制）进行评估，以确定 NRE（以天然气、燃料和煤炭衡量）对预期寿命的缓和或加剧影响。实证分析以一组初步检验为基础，分别由横截面相关检验、面板单位根检验和协整检验组成。归根结底，采用完全改进的OLS面板方法进行模型估计。实证结果揭示了 NRE 对模型中预期寿命的负面影响。除了，收入水平的积极影响有助于抑制非可再生能源对预期寿命的负面影响，而制度质量的负面影响则进一步加剧了这种影响。可再生能源和碳排放对预期寿命的影响则相反。根据这些产生的结果，提出了相关的政策影响。
