本文提出基于居住地的国内增加值出口概念和贸易测度方法，分析G20经济体的出口活动，发现新测度下发达经济体持续获益，而发展中经济体贸易顺差大幅减少，表明大量额外价值从发展中流向发达经济体。
Abstract This paper examines flow of value that goes with trade flows in global value chains (GVCs) by a residence‐based domestic value‐added trade measure. Accordingly, the paper puts forward a concept of residence‐based domestic value‐added exports from activity domains and develops a corresponding trade measure. Export activities of G20 economies are scrutinized empirically, with which sizeable differences are observed between figures in the proposed residence‐based domestic value‐added trade measure and the conventional domestic value‐added trade measure. This calls for new measures, to which the present study responds. It has been demonstrated that the developed G20 gains persistently in residence‐based domestic value‐added exports, increasing from the conventional domestic value‐added exports measure. Whereas trade performance of the developing G20 deteriorates with considerably reduced surpluses in the new measure. Considerable additional value flows out from developing to developed economies in GVCs. Developed economies continue to gain from international trade as a matter of fact.
