本研究基于2009-2015年我国116家A股上市的制造业跨国企业面板数据,从投资广度和投资深度视角研究ODI对我国制造业跨国企业生产率的影响效果,研究结果表明:总体来说,我国制造业跨国企业ODI投资区域越广泛,对企业生产率的提升效果越明显,增加ODI投资深度对企业生产率无显著影响;此外,不同ODI进入模式对我国制造业跨国企业生产率的影响效果存在明显差异性,绿地投资模式下ODI投资广度的正向影响效果比跨国并购模式更明显,而跨国并购模式下增加ODI投资深度比绿地投资模式更能促进企业生产率提升;独资经营模式下ODI投资广度和投资深度对企业生产率的正向影响效果均比合资经营模式更显著。 Based on panel data of 116 multinationals manufacturing MNCs listed in China from 2009 to 2015, this study studies the effect of ODI on the productivity of MNCs in China from the perspective of investment breadth and investment depth. The results show that: Overall, The more extensive the ODIs of manufacturing MNCs are, the more obvious the effect is to enhance the productivity of enterprises. Increasing the investment depth of ODI has no significant effect on the productivity of enterprises. In addition, the effects of ODI entry modes on the productivity of manufacturing MNCs in China are significantly different , The positive effect of ODI investment in greenfield investment mode is more obvious than that in cross-border M & A, while the increase of ODI investment in cross-border M & A mode can promote the productivity of enterprises more than the greenfield investment mode. The investment scope and investment depth of ODI in sole proprietorship mode The positive effect on enterprise productivity is more significant than that of joint venture.
