Environmental expenditures (EX) are made by the government and industries which are either long-term or short-term investments. The principal target of EX is to eliminate environmental hazards, promote sustainable natural resources, and improve environmental quality (EQ). Thus, this study looks at the impact of economic growth (EG), and government finance expenditure (GEX) on EQ in Northern Africa and Southern Africa (NASA) republics from 2000-2016. The panel quantile regression (PQR) and panel vector autoregressive (PVAR) model in a generalized method of moment framework (GMM) were employed as a framework. The PQR results show that; (i) In Northern republics, GEX had a significant positive effect on EQ at 25%, 50%, and 75% quantiles levels. (ii) In the Southern republics, GEX had a significant negative impact on EQ at 25%. Moreover, the PVAR through the GMM established that EG and GEX are significantly positive while the parameter for CO is insignificant and negative in the North. However, in the South, GEX and CO were statistically significant, while EG positively impacts EQ. Lastly, the granger causality report in North indicates uni-directional causation running from LNGEX → LNGDPpc, LNCO → LNGDPpc, LNFF → LNGEX, and LNFDI → LNGEX. Similarly, there is uni-directional causation in South republics from LNGEX → LNGDPpc, LNCO → LNGEX, and LNFDI → LNGEX.
环境支出（EX）由政府和行业进行，这些支出是长期或短期投资。EX 的主要目标是消除环境危害、促进可持续自然资源和提高环境质量（EQ）。因此，本研究考察了经济增长（EG）和政府财政支出（GEX）对 2000-2016 年北非和南部非洲（NASA）共和国 EQ 的影响。面板分位数回归（PQR）和面板向量自回归（PVAR）模型在广义矩方法（GMM）框架下被用作框架。PQR 结果表明：（i）在北方共和国，GEX 在 25%、50%和 75%分位数水平上对 EQ 有显著的正影响。（ii）在南方共和国，GEX 对 EQ 有显著的负面影响，在 25%分位数水平上。此外，通过 GMM 建立的 PVAR 表明，EG 和 GEX 在北方呈显著正相关，而 CO 的参数则不显著且为负。然而，在南方，GEX 和 CO 在统计上是显著的，而 EG 则对 EQ 产生积极影响。最后，北方的格兰杰因果报告表明，从 LNGEX→LNGDPpc、LNCO→LNGDPpc、LNFF→LNGEX 和 LNFDI→LNGEX 存在单向因果关系。同样，在南方共和国，从 LNGEX→LNGDPpc、LNCO→LNGEX 和 LNFDI→LNGEX 也存在单向因果关系。
