外商直接投资的技术溢出效应研究——技术差距视角下的—个理论模型

本文通过将Barro和Martin的领导者一追随者模型扩展至包含外商投资部门，构建了技术差距对FDI溢出影响的理论模型，并得出如下结论：外资企业通过技术溢出效应提高了东道国企业的生产效率，即FDI的技术溢出效应是存在的；对于存在不同程度技术差距的内外资企业，技术差距对FDI溢出效应的作用不同；当内外资企业技术差距过大时，外资企业技术水平的提高不会产生更显著的技术溢出，反而由于东道国企业难以吸收而抑制外资企业的技术溢出。

Technology Spillover Effect of Foreign Direct Investment The Technology Gap Perspective of a Theoretical Model

This paper extends Barro and Martin＇s leader-follower model to include the foreign-invested sector, and build the theoretical model of technology gap on FDI overflow effect. This paper draws the following conclusions： first, Foreign- funded enterprises raise production efficiency of the host countries through technical spillover effects; in the second place, the role of FDI spillovers is different between different degrees of technology gap.When technology gap between domestic and for- eign enterprises is too large, Technology gap suppresses technology spillover of foreign-funded enterprises because of the host country enterprises is difficult to absorb.
