中文摘要：

不同于国内外既有基于贸易角度的国际研发知识外溢研究，文章在价值链国际分工背景下，重点关注了制造业细分行业研发知识存量异质性对国际知识外溢的影响。主要结论表明：只有在与国际研发知识存量资源相结合的情况下，价值链国际分工网络渠道的进一步扩张及由此形成的研发知识溢出，才能够真正体现出价值链国际分工对我国制造业部门劳动生产率水平提升的促进作用，且是价值链国际分工影响我国制造业部门效率水平提升非常稳定的作用机制。

英文摘要：

Different from the domestic and foreign researches on the international knowledge spillover from the perspective of trade, this paper, under the background of international division of value chain, mainly focuses on the influence of heterogeneity of knowledge stock of manufacturing industry on international knowledge spillover. The main results indicate that： only Combined with international knowledge stock resources can the channel expansion of global production network and the knowledge spillover formed by it truly promote the productivity of manufacture, which is also a very stable mechanism.
