英文文献摘要：
This work evaluates the effect of the Generalised System of Preferences (GSP1) on EU’s fruit imports from Southern African Development Community (SADC) member countries during 2005-2014, using a new and advanced micro-econometric tool known as the Triple-Difference estimator. The estimator is advantageous given that it is robust to policy endogeneity and it uses a very flexible benchmark to which the intensive margin and extensive margin of trade performance are compared. Two preference margin measures are used as proxies for the preferential treatment granted to SADC member countries by the EU. Furthermore, highly disaggregated data at HS 6-Digit level, for 12 SADC member countries and 27 EU member states are used for the analysis. The analysis employed takes into consideration of zero-trade flows. Empirical results suggest that the EU-GSP scheme generally has a significant positive impact on EU’s fruit imports from SADC member countries. Notably, the Least Developed Countries (LDCs) benefited more from the scheme as compared to the non-LDCs.

本研究使用一种被称为三差估计器的新型先进微观计量工具，评估了2005-2014年期间GSP1对欧盟从南部非洲发展共同体(SADC)成员国进口水果的影响。该估计器具有优势，因为它对政策内生性具有鲁棒性，并且它使用了一个非常灵活的基准来比较贸易绩效的密集边际和广泛边际。两种优惠幅度措施被用来代替欧盟给予南共体成员国的优惠待遇。此外，还使用了12个南共体成员国和27个欧盟成员国在HS 6位水平上高度分类的数据进行分析。所采用的分析考虑了零贸易流。实证结果表明，欧盟-普惠制对欧盟从南共体成员国的水果进口总体上具有显著的正向影响。值得注意的是，最不发达国家比非最不发达国家从该计划中获益更多。
