FDI技术外溢、技术差距与经济增长的非线性关系

摘要

Based on the assumption of the linear relationship of technological spillovers of inward FDI, technol-ngy gap and economic growth from the majority literatures, this paper studies the nonlinear relationship of tech-nological spillovers of inward FDI, technology gap and economic growth. The authors establish an economic growth model through introducing an inward FDI variable into the physical capital and a technology gap variable into the technological spillover, and then construct the quantitative estimate equation. Moreover, the estimated results of the panel data from 29 provinces in China proves that there is an inverted U-shaped nonlinear relation-ship between technology gap and economic growth, which significantly influences on the growth effect of each region.%针对大多数文献所采用的FDI技术外溢、技术差距与经济增长存在线性关系的假设,本文探讨FDI技术外溢、技术差距与经济增长的非线性关系.通过在物质资本中引入FDI、在技术外溢中引入技术差距建立了增长模型进行理论分析,并在此基础七构建了定量分析的估计方程.基于中国29个省市面板数据的估计结果表明,技术差距与经济增长之间存在倒U型的非线性关系,而且其对中国各地区的增长效应存在显著差异.
