This paper employed the autoregressive distributed lag (ARDL) methodology to examine the effect of electricity transmission and distribution losses (ETL) on the economic growth of South Africa over the period 1971-2014. After controlling for foreign direct investment (FDI) and financial development, the results of the study show long-run negative relationship between ETL and economic growth. For robustness checks, we account for non-linearities/asymmetries in our model and find that a percentage increase in ETL decreases economic growth from 3.786% to 2.245%. The correction of the distortions of the convergence to long-run equilibrium by temporary shocks is reduced from 30.4% to 25.1%. Additionally, financial development and gross fixed capital formation promote growth while FDI and trade have insignificant effect.
本文采用自回归分布滞后（ARDL）方法，研究了1971 - 2014年期间输电和配电损耗（ETL）对南非经济增长的影响。在控制了外国直接投资（FDI）和金融发展因素后，研究结果表明ETL与经济增长之间存在长期负相关关系。为进行稳健性检验，我们在模型中考虑了非线性/非对称性，发现ETL增加一个百分点会使经济增长从3.786%降至2.245%。由临时冲击对长期均衡收敛扭曲的修正从30.4%降至25.1%。此外，金融发展和固定资本形成总额促进了增长，而FDI和贸易的影响不显著。
