The first target of Goal 17 of the Sustainable Development Goal (SDG) emphasizes the need to strengthen domestic resource mobilization and improve revenue collection. However, the average tax‐to‐GDP ratio is much lower than the optimal threshold required to finance development. Meanwhile, Africa is losing a significant amount of its capital through illicit financial flows, primarily driven by trade misinvoicing, but at the same time offering fiscal incentives and improving governance to create an environment for increased domestic revenue. Using random and fixed effects models, the study examines the tax revenue effects of trade misinvoicing, and further examines the extent to which tax holidays and regulatory quality dilute or deepen the revenue effects of trade misinvoicing for 13 African countries over the period 2000 to 2015. The results suggest that trade misinvoicing reduces tax revenue. While tax holiday strengthens the effect of trade misinvoicing, regulatory quality dilutes the effect of trade misinvoicing on tax revenue. The study, therefore, recommends that the governments of SSA should promote good governance, reduce trade misinvoicing and review existing tax incentives as critical components of the ongoing efforts to increase domestic resource mobilization for development.

贸易发票错误对撒哈拉以南非洲地区税收的影响：免税期和监管质量的作用

可持续发展目标（SDG）的目标17的第一个目标强调需要加强国内资源动员和改善税收。但是，平均税收与GDP的比率远低于为发展筹集资金所需的最佳门槛。同时，非洲主要通过贸易发票错误导致的非法资金流失大量资本，但同时提供财政激励措施并改善治理，以创造增加国内收入的环境。该研究使用随机效应和固定效应模型，研究了贸易虚假发票的税收影响，并进一步研究了2000年至2015年期间免税期和监管质量在多大程度上稀释或加深了13个非洲国家贸易虚假发票的税收影响。结果表明，贸易虚假发票会减少税收。免税期加强了贸易发票错误的影响，而监管质量却削弱了贸易发票错误对税收的影响。因此，该研究建议，撒哈拉以南非洲国家的政府应促进善治，减少贸易错误开具发票，并审查现有的税收优惠政策，将其作为不断努力增加国内资源调动发展的重要组成部分。
