This research documents facts and offers an empirical appraisal of the contribution of trade in services for African participation in global value chains. It adopts a comparative approach among flows, service categories and positions in a global value chain, using data for a panel of 36 sub‐Saharan African countries from 2000 to 2017. The empirical analysis, using generalized method of moments in system, leads to three main results on the trade in services and global value chain nexus in Africa. First, the relationship is linear and positive. Secondly, exportations of services have a lower effect than importations of services, whatever the position in a global value chain. Thirdly, some services have a positive outcome on both backward and forward participation in global value chains, while others have a one‐sided effect. Those results give African countries tools to set a comprehensive and rationalized strategy to deepen and upgrade their participation in global value chains using trade in services.

服务贸易会改善非洲对全球价值链的参与吗？

这项研究记录了事实，并提供了服务贸易对非洲参与全球价值链的贡献的实证评估。它采用了全球价值链中流量，服务类别和位置之间的比较方法，使用了2000年至2017年撒哈拉以南非洲36个国家/地区的面板数据。使用系统中矩的广义方法进行的实证分析得出三个非洲服务贸易和全球价值链联系的主要成果。首先，该关系是线性和正的。其次，无论在全球价值链中的地位如何，服务出口的影响都低于服务进口。第三，某些服务对全球价值链的后向和前向参与都有积极的结果，而其他服务则具有单方面的影响。
