This study examined the impact of regional economic integration on economic upgrading in global value chains (GVCs), of the East African Community (EAC), Southern African Customs Union (SACU) and the Economic Community of West African States (ECOWAS), from 2000 to 2015. Using the Least Square Dummy Variable (LSDV) technique, the results showed that regional economic integration is not a significant driver of the economic upgrading of their Members, in GVCs but one-period lagged backward participation in GVCs is. Considering labour productivity as an alternative measure of productivity in the place of productivity linked with participation in GVCs (economic upgrading), regional economic integration turned out to be a weak positively significant determinant. At a disaggregated level, regional economic integration significantly determined labour productivity in both EAC and SACU but not in ECOWAS. More regional efforts are needed to sufficiently aid the contribution of these African RECs to their Members' economic upgrading in GVCs.
本研究考察了2000年至2015年期间东非共同体（EAC）、南部非洲关税同盟（SACU）和西非国家经济共同体（ECOWAS）的区域经济一体化对全球价值链（GVCs）中经济升级的影响。运用最小二乘虚拟变量（LSDV）技术，结果表明，区域经济一体化并非其成员国在全球价值链中经济升级的重要驱动因素，而滞后一期的全球价值链逆向参与则是。将劳动生产率作为生产率的替代指标，以取代与参与全球价值链（经济升级）相关的生产率，结果表明区域经济一体化是一个微弱的正向显著决定因素。在细分层面上，区域经济一体化显著决定了东非共同体和南部非洲关税同盟的劳动生产率，但对西非国家经济共同体则不然。需要更多的区域努力来充分帮助这些非洲区域经济共同体推动其成员国在全球价值链中的经济升级。
