Studies on the environmental impacts of China-African trade relations are scarce. To fill the gap, this research examines the effects of Sino-African trade relations on carbon dioxide (CO) emissions intensity in Africa, employing panel quantile regression for 39 African countries over the period of 1992-2015. The results indicate that imports have a negative and significant effect on CO emissions intensity across all quantile distributions, whereas exports have a positive and significant effect, except at the 25th and 35th quantiles. The findings also confirm the inverted U-shaped environmental Kuznets curve hypothesis, particularly for countries at higher emissions points. The study also demonstrates that urbanisation and energy intensity positively affect CO intensity, while the effect of foreign direct investment is negative and significant, confirming the pollution halo hypothesis. Finally, policy implications are presented based on the findings of the study.
关于中非贸易关系的环境影响的研究很少。为了填补这一空白，本研究利用面板分位数回归方法，考察了 1992 年至 2015 年期间中非贸易关系对非洲二氧化碳（CO）排放强度的影响，研究对象为 39 个非洲国家。结果表明，进口对 CO 排放强度的影响在所有分位数分布中均为负且显著，而出口的影响则为正且显著，除了在第 25 和第 35 分位数处。研究结果还证实了环境库兹涅茨曲线假说的倒 U 型，特别是对于排放水平较高的国家。研究还表明，城市化和能源强度会正向影响 CO 排放强度，而外国直接投资的影响则为负且显著，证实了污染光环假说。最后，根据研究结果提出了政策建议。
