技术差距的门槛与FDI技术溢出的非线性——理论模型及中国企业的实证研究

Threshold of Technology Gap and Non-linearity of Technology Spillovers of FDI

本文通过引入内外资技术差距的"双刃性"改进质量阶梯型内生增长模型,从理论上证明了存在内外资技术差距的门槛值,使得外商直接投资技术溢出受技术差距的影响而呈现非线性动态演进规律;进一步结合我国14474家微观企业面板数据,证明了存在两个技术差距的门槛值,使得外商直接投资企业对于落在不同技术差距范围内的内资企业具有不同的技术溢出效应。

By introducing double-edged roles of technology gap into the quality- ladder endogenous growth model, this paper shows that there may exist the threshold value, which results in the non-linear evolution property of technology spillovers of FDI. Based on 14474 firms level panel date in China, the empirical results are robust to support there are two technology gap＇s threshold values, which lead to the FDI spillover effects vary cross firms who belong to different range of technology gap.
