摘要

本研究的主要目的是分析煤炭价格变化的影响。学者们暗示,建设火电厂和煤矿的大量资金需求导致电力生产成本大幅下降,超出了许多经济参与者的承受能力。这些上涨的成本在煤价和电力生产成本上升的情况下,电力零售价格一直没有调整,导致这个行业的很多参与者都出现了亏损。本研究将采用统计多元回归和相关分析来检验两个变量之间的关系,其中煤价变化为自变量,电价变化为因变量。研究结果显示,南非煤炭价格的变化和电价之间存在很强的依赖性。人们争相采煤是一个令人担忧的问题,因为没有适当的监管会导致土地退化。此外,由于NERSA监管电价,矿工被迫使用更便宜的方法开采煤炭,以保持低成本。

Impact of coal prices changes on prices of electricity in South Africa
The main purpose of this research is to analyze the impact of changes in coal prices. Scholars insinuated that the extensive capital requirements of building thermal power stations and coal mines lead to power production costs parachuting beyond the reach of many economic players. These rising costs in coal prices and power production costs, the retail price of electricity has not been adjusted, resulting in many players in this industry incurring losses. This study will use Statistical multiple regression and correlation analysis to test the relationship between two variables, coal price changes being an independent variable and changes in the price of electricity being the dependent variable. The findings show a strong dependence between changes in coal prices and electricity pricing in South Africa. People scrambling to coal mining is a concern since no proper regulations lead to land degradation. Moreover, since NERSA regulates electricity prices, miners are forced to use cheaper methods of extracting coal to keep the costs low.
