本文研究了撒哈拉以南非洲地区贸易平衡的可持续性，使用了Im等人（2003）提出的面板单位根（Im - Pesaran - shin (IPS)）检验和Pesaran（2007）提出的IPS的横截面增强版（Pesaran横截面IPS (CIPS)）检验，其中前者检验基于横截面独立性的假设，后者实际上考虑了横截面独立性。尽管基于IPS检验的实证结果表明撒哈拉以南非洲地区的贸易平衡是可持续的，但基于CIPS检验的实证结果表明，该地区的贸易平衡是不可持续的。由于横截面依赖（CD）是使用Pesaran（2004）开发的CD测试来识别的，因此基于IPS测试的实证结果有可能是虚假的。
This article investigates the sustainability of trade balances in the sub-Saharan African regions, using both the panel unit root (Im–Pesaran–Shin (IPS)) test proposed by Im et al. (2003) and the cross-sectionally augmented version of the IPS (Pesaran Cross-sectional IPS (CIPS)) test suggested by Pesaran (2007), where the former test is based on the assumption of cross-section independence and the latter actually considers cross-section independence. Although the empirical results based on the IPS test indicate that the balance of trade in the sub-Saharan African regions is sustainable, the empirical results of the CIPS test reveal that it is not sustainable. Since Cross-section Dependence (CD) was recognized using the CD test developed by Pesaran (2004), there is a possibility that the empirical results based on the IPS test are spurious.
