生产性服务进口、服务化与制造业出口增加值

基于WIOD及相关数据库公布的数据，探究生产性服务进口对制造业出口增加值的影响以及制造业服务化在此过程中的作用。研究发现，生产性服务进口对制造业出口增加值的提升有显著的促进作用。并且，在此过程中，制造业服务化发挥着关键影响；制造业服务化水平越高，越有助于生产性服务进口影响的发挥；制造业服务化水平与生产性服务进口水平相对差距越小，生产性服务进口的正向影响也越明显。进一步分析显示，在一定的服务化水平下，生产性服务进口质量和数量边际的增长是其发挥作用的主要动力。中国应当重视生产性服务进口的正向效应，明确制造业服务化和进口增长来源差别所形成的关键作用，从制造业服务化战略推进、产业发展与进口贸易协调、服务进口贸易战略调整等方面促进生产性服务进口作用的发挥。

Productive Services Import,Servitization and Domestic Value Added in Manufacturing Export

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.
