This article examines the effect of Aid for Trade (AfT) flows on services export diversification in recipient countries. The empirical analysis has relied on a sample of 100 recipient countries (of which 31 least developed countries [LDCs]) over the period 2002–2014, and used the two-step system generalised methods of moments (GMM) approach. It shows that total AfT as well as its components—AfT for services sectors and AfT for non-services sectors—exert a positive effect on services export diversification over the full sample. Additionally, over the full sample, there is a positive effect of the cumulative AfT flows over time (for both total AfT flows and its components) on services export diversification. However, findings are different for LDCs and NonLDCs. Specifically, AfT for services sectors exerts a positive effect on services export diversification in both LDCs and NonLDCs, although the magnitude of this positive effect is higher for NonLDCs than for LDCs. Furthermore, the effect of the cumulative AfT flows for services sectors and that of the cumulative AfT flows for services sectors are positively associated with services export diversification in both LDCs, and NonLDCs, with the magnitude of the positive effects being higher in LDCs than in NonLDCs.

受援国贸易和服务出口多样化援助

本文研究了贸易援助 (AfT) 流动对受援国服务出口多样化的影响。实证分析依赖于 2002-2014 年期间 100 个受援国（其中 31 个最不发达国家 [LDC]）的样本，并使用了两步系统广义矩法 (GMM) 方法。它表明，总的 AfT 及其组成部分——服务部门的 AfT 和非服务部门的 AfT——对整个样本的服务出口多元化产生了积极影响。此外，在整个样本中，累积 AfT 流量随着时间的推移（对于总 AfT 流量及其组成部分）对服务出口多样化有积极影响。然而，最不发达国家和非最不发达国家的调查结果不同。具体来说，服务业的贸易援助对最不发达国家和非最不发达国家的服务出口多样化产生积极影响，尽管这种积极影响对非最不发达国家的影响程度高于最不发达国家。此外，服务部门的累计 AfT 流量和服务部门的累计 AfT 流量的影响与最不发达国家和非最不发达国家的服务出口多样化呈正相关，最不发达国家的积极影响程度高于非最不发达国家.
