【摘要】 通过双固定效应面板模型和差分GMM模型实证检验2007-2019年49个国家的双向国际直接投资对全球价值链地位的影响，论证OFDI与FDI交互项的调节作用，并分析不同水平的双向国际直接投资对全球价值链地位的异质性影响。研究发现：双向国际直接投资对全球价值链地位均呈现显著正向影响，即具有明显的“强链”作用，但FDI的促进作用明显高于OFDI;OFDI与FDI的交互项显著为负，OFDI与FDI存在竞争与对抗效应，削弱彼此对全球价值链的促进作用；高低不同水平的双向国际直接投资对全球价值链地位存在异质性影响，其中高水平OFDI组对全球价值链地位的促进作用显著高于低水平OFDI组；低水平FDI组呈现显著促进作用，而高水平FDI组促进作用不显著。更多还原

【Abstract】 Using the sample data of 49 countries in ADB database from 2007 to 2019, this paper empirically tests the “enhance chain” effect and of two-way foreign direct investment(Two-way FDIs)on global value chain(GVC) position by the dual fixed effect panel model and dynamic GMM model. In addition, it also testifies the effects of interaction terms and two-way FDIs at different levels. The results show that: Two-way FDIs do have a significant positive correlation with GVC position, which are the “enhance chain” effects, but the positive promotion effect of FDI is higher than that of OFDI; The interaction terms show a siginificant negative effect of GVC position, that is, FDI and OFDI have competitive and antagonistic effects that weaken each other′s contribution to global value chains; There are heterogeneous effects of different levels of Two-way FDIs on GVC position. The group of higher-level OFDI shows a stronger positive effect than the low-level OFDI group, low-level FDI shows a siginificant positive effect on GVC position, while the high-level FDI does not show any significant effect.更多还原
