全球服务贸易的快速增长及其蕴含的创新知识，构成了开放条件下知识外溢的又一重要源泉。本文基于跨服务行业面板数据，在充分考虑行业研发知识源异质性前提下，经研究证实：中国服务贸易进口下的研发知识外溢效应是存在的，经由外溢结构分解，其不仅表现在产业内知识外溢效应方面，更体现在产业间知识外溢效应方面；由于技术禀赋差异和更高的协同生产要求，服务产业间知识外溢相对服务产业内知识外溢具有更显著的效率水平提升作用；研究最后亦证实，服务产业内、产业间知识外溢效应均存在明显的非线性作用规律，而这并没有妨碍两者的互补效应及其正向影响。

The rapid growth in the service trade and its R＆D knowledge con- stitute another sottrce of knowledge spillover in the open economy. Based on the cross- industry panel data, and fully underscoring the heterogeneity of knowledge source, this paper investigate into significant knowledge spillovers of international service trade, in both intra- industry and inter- industry forms. A further discus- sion shows that under the ＂south- north＂ cooperation mode and for technology- intensive service trade, more apparent knowledge spillovers are seen. Finally, due to the existence of complementary effects between two kinds of knowledge spill- overs, this study also affirms the existence of non- linear influences, which do not obstruct the formation of complementary effects and their positive influence on service productivity.
