Based on the panel data of 108 cities from 2003 to 2016, this paper empirically analyses the effect of FDI on economic growth in the Yangtze River Economic Belt by using threshold regression model. The results show that FDI plays a positive role in promoting economic growth in the Yangtze River Economic Belt, and the effect depends on the increase of FDI utilizing ability, the expanding of FDI scale, the accumulation of human capital and the expanding of firm size. Moreover, the effect and the threshold of FDI on economic growth are different in different regions of the Yangtze River.
