摘　　要：本文以2006—2016年257个城市的面板数据为样本,基于面板门槛模型,以城市工资水平为门槛变量,实证分析了FDI对城市创新能力的非线性影响。结果表明:FDI对城市创新能力的影响存在显著的以工资水平为门槛的双门槛效应,即当工资水平未跨越第一门槛值时,FDI流入显著抑制了城市创新能力的提升;当工资水平跨越第一门槛值后,FDI流入对城市创新能力的影响由负转正,但不显著;只有当工资水平跨越第二门槛值后,FDI流入才显著促进了城市创新能力的提升。This paper takes the panel data of 257 cities in China from 2006 to 2016 as the sample and uses the wage level as the threshold variable to analyze the nonlinear impact of FDI on urban innovation capabilities.The result shows that:the impact of FDI on urban innovation capability has a significantly double threshold with the wage level as threshold.When the wage level fail to cross the first threshold,FDI could significantly inhibits the promotion of urban innovation abilities.However,when the wage level crosses the first threshold,the significantly negative impact of FDI on urban innovation capabilities will be turned into a positive impact but not significant.Only when the wage level crosses the second threshold can FDI have a significantly positive impact on the cities'innovation abilities.
