中文摘要：

首先分析了现有文献中在测算FDI产业关联指标时的假定（国内资本的直接消耗系数等于FDI的直接消耗系数）与我国现实的相符程度,然后利用相关统计资料推导出适当放宽该假定后测算FDI产业关联的方法,最后利用2003—2010年我国制造业行业的数据,检验了放宽该假定是否显著影响我国FDI产业关联指标的测算结果及FDI垂直溢出效应的研究结论。结果显示：放宽该假定对我国FDI产业关联指标的测算结果和FDI垂直溢出效应的研究结论均有显著影响。据此指出：在研究相关FDI产业关联问题时,适当放宽该假定能得到更可靠的研究结论。

英文摘要：

Starting with the assumption that the direct consumption coefficient of domestic capital equals to that of FDI,this paper,on the basis of literature review on the measurement of FDI intra-industrial linkage,analyzes the agreement of the above assumption with the reality in China.Then,using the Chinese public statistical data,it derives an improved measurement of FDI＇s intra-industrial linkage under the relaxed assumption.Finally,it uses the data of China＇s manufacturing industries from 2003to 2010to test whether the relaxed assumption influence the measurement result of FDI intra-industrial linkage and the research conclusion of FDI＇s vertical spillover effect or not.The result shows that the relaxed assumption affects the research conclusion of FDI＇s vertical spillover effect and the measurement result of FDI＇s intra-industrial linkage significantly.The findings indicate that,relaxing the assumption helps to make the research conclusions more reliable when studying the intraindustrial linkage of FDI.
