AfCFTA Seven Years: The Capital Paradox of Intra-African Trade

2025年6月，纳米比亚向尼日利亚发运了2.5万吨盐。这不是一单普通的贸易，而是AfCFTA框架下纳米比亚的首笔出口。大洋彼岸的全球贸易正在经历特朗普关税带来的震荡，非洲大陆却试图用一船盐证明：一个覆盖55个成员国的单一市场正在从纸面走向现实。

然而，从资本市场的角度看，这艘盐船更像一面镜子，映照出非洲内部贸易和资本流动的深层悖论。非洲大陆自由贸易区（AfCFTA）自2018年签署以来，已有48国批准，但只有19国公布了关税减让表。政策与执行之间的鸿沟，折射出非洲资本布局的核心问题：资本为何不流向非洲内部？

资本不愿进入的“单一市场”

AfCFTA的目标是打破非洲内部关税与非关税壁垒，让商品、服务、资本和人员在成员国之间自由流动。但七年过去，非洲内部贸易占其全球贸易的比重始终在15%至21%之间波动。作为对比，世界银行数据显示，2025年亚洲内部贸易已占其总贸易的60%。这意味着非洲国家之间的经济联系仍然远弱于它们与外部世界的联系。

从资本流动的视角看，这一数据揭示了一个尴尬的事实：非洲的原材料仍在以前所未有的规模流向中国、欧洲和美国，而非洲内部的资本交易和产业投资却因市场碎片化而受阻。资本习惯于沿着最可预测的路径流动，而AfCFTA尚未提供足够可预测的规则和基础设施。

资金流向：基础设施赤字的“中国答案”

基础设施是AfCFTA能否落地的物理前提。但整个大陆的铁路网络依然稀疏，港口投资长期不足。为了弥补缺口，不少非洲国家转向中国，通过双边合作或中国主导的基础设施融资获得港口、铁路和公路建设资金。这并非没有代价：基础设施融资中国化，反而强化了非洲对单一外部伙伴的依赖。

这种融资结构产生了双重效应：一方面，中国资金填补了非洲基础设施的投资缺口；另一方面，基础设施的建设和运营往往绑定中国标准、中国设备和中国企业，使得非洲内部的互联互通并未因此提升。更关键的是，港口和铁路的布局更多服务于资源出口和矿产运输，而非满足区域内制造业供应链的需求。资本在物理上被引向外部，而非内部。

政治经济学的资本逻辑

AfCFTA的实施还包括国家不愿意放弃关税收入。对于财政脆弱的国家，关税是重要的财政收入来源。打开国门迎接区域内竞争者，意味着短期内财政收入下降，而区域内贸易带来的长期收益又高度不确定。这种不确定性让资本更加谨慎。Additionally, the ruling blocs of some African countries rely on "clientelist" trade relationships with external partners to maintain domestic power structures. Genuine free trade requires domestic legal and regulatory frameworks to be opened up to regional partners, which touches on vested interests. Therefore, when capital flows within Africa, it faces not only physical barriers but also political barriers.

Regional investment centers remain unchanged, but a competitive landscape has emerged

Even though the AfCFTA is not yet fully operational, its existence is already reshaping regional investment expectations. Regional mechanisms such as the Southern African Customs Union (SACU) and the Common Market for Eastern and Southern Africa (COMESA) face pressure to be integrated into or displaced by the AfCFTA. For investors, this brings both risks and opportunities—if the AfCFTA truly takes hold, countries with more developed infrastructure and legal systems may become new regional capital hubs.

But the reality is that regional investment centers have not undergone a fundamental shift. South Africa still attracts the most capital in Southern Africa, while resource-rich and populous countries such as Nigeria continue to dominate capital inflows. Namibia's salt exports show that small countries can participate in continental trade, but without supporting logistics and financial services, such participation is difficult to expand into large-scale industrial investment.

Long-term capital trends: Will Africa be re-evaluated?

Over the next five to fifteen years, whether Africa can benefit from the AfCFTA depends on two variables: first, whether domestic reforms can eliminate tariff and non-tariff barriers; second, whether the external environment continues to deteriorate, forcing African countries to forge internal solidarity. The Trump administration's punitive tariffs have already caused African economies to feel the pain firsthand, which may accelerate the implementation of the AfCFTA.

From a capital markets perspective, Africa's most attractive long-term story remains its demographic structure: young, fast-growing, and accelerating urbanization. If the AfCFTA can reduce cross-border trade costs, manufacturing may gradually shift from Asia to Africa, particularly in textiles, automobile assembly, and agricultural product processing. However, this prospect currently faces the dual constraints of infrastructure deficits and political inertia.

Africa's capital story is being rewritten, but it is far from its finale. Seven years of the AfCFTA serve as a mirror, showing global investors that Africa's potential and obstacles coexist. Whether capital will re-evaluate Africa's investment value on a large scale depends on whether African countries are willing to translate political commitments into market rules. And that, perhaps, is a longer journey than the road traveled by ten thousand tons of salt.
