Abstract: Based on data published by WIOD and its relevant database, this paper studies the effect of import of productive services on export value added of manufacturing and also the character that servitization of manufacturing plays during this process. The study shows a significant positive effect of import of productive services on export value added of manufacturing, and the higher the level of servitization of manufacturing is, the more productive effect of import of productive services will be. Moreover, the smaller the relative gaps between the level of servitization of manufacturing and import of productive services on export is, the more positive and significant the import of productive services will be. Further study shows that under the certain level of servitization, the growth of both quality and quantity are the main drive of this effect. Chinese's government should attach importance to this positive effect, and specified the pivotal role from both servitization of manufacturing and the different origins of import's growth. Moreover, government should improve the effect by three critical channels:to carry forward the strategy of servitization of manufacturing, to coordinate the development of industry and import trade, and to make the adjustment of import of service trade strategy etc.

Key words: productive services import, servitization, domestic value added in manufacturing export
