This study answers an important policy question related to energy efficiency transition tendencies and the role that control of corruption and regulatory quality can play, using the Stochastic Frontier and Panel Markov-Switching techniques with panel data from 46 African countries. We have demonstrated in this study that African countries have been locked in a low energy-efficient state, with tendencies to transition out considered low to moderate with a 21-24% chance and more likely in the long term (i.e., after a decade). This raises serious concerns about the robust nature of current energy efficiency policies implemented and the kind of investment in technology undertaken in Africa. The results further illustrate that improving regulatory quality and controlling corruption can increase African countries' likelihood to leapfrog out of the low energy-efficient state. Thus, the findings underscore the importance of developing better and proper institutions to achieve the UN SDG target 7.3.
本研究利用随机前沿和面板马尔可夫切换技术，结合46个非洲国家的面板数据，回答了一个与能源效率转型趋势以及控制腐败和监管质量所能发挥的作用相关的重要政策问题。我们在本研究中表明，非洲国家一直被困在低能源效率状态，向低到中等程度的转型倾向概率为21%-24%，且从长期来看（即十年后）更有可能实现转型。这引发了对非洲当前实施的能源效率政策的稳健性以及所进行的技术投资类型的严重担忧。结果进一步表明，提高监管质量和控制腐败可以增加非洲国家摆脱低能源效率状态的可能性。因此，研究结果强调了建立更好、更合适的制度以实现联合国可持续发展目标7.3的重要性。
