The relationship between the economic growth and foreign direct investment (FDI) has been the concern of the researchers. The grey Lotka-Volterra model is employed to analyze the relationship between the gross domestic products (GDP) and FDI in Ningbo from 1999 to 2007. The discrete Lotka-Volterra model is applied to predict the GDP and the FDI in Ningbo respectively. The results demonstrate that there is mutually beneficial relationship between the GDP and the FDI in Ningbo in the long run, and the FDI of current year restricts economic development.
