This study examines the industrial transmission mechanisms between producer services imports and manufacturing advantages in RCEP economies. Based on the framework of GVCs'decomposition, we establish a hierarchical linear model (HLM) withthe data from 2007 to 2017 in the ADB MIRO, WTO BaTiS and WITS databases to analyze the impact of producer services imports in RCEP economies on the value-added domestic exports of manufacturing in countries around the world, and the conclusions are as follows: (1) Producer service imports have a significant positive impact on the domestic value-added of manufacturing exports through direct effects, upstream effects and downstream effects. The downstream effect is the main driving force for the improvement of manufacturing. After using instrumental variables to resolve endogeneity, the conclusion remains stable; (2) The downstream effect of insurance imports is the largest among producer services imports. After the outbreak of the world financial crisis, the transmission effect of the industry chain was higher in 2008 than before the crisis. (3) Due to the high degree of specialization of industrial division in developed economies, the transfer effect of the three major industrial chains is greater than that of developing countries and regions.
