RETRACTED: Study of Xiamen's Economic Growth Based on the Stochastic Time Series Model (Retracted Article)

Based on the stochastic time series model, in order to study the correlation between Xiamen's investment in fixed-asset and GDP, this paper establishes the transfer function model of them and analyses the lagging effects of fixed asset investment for GDP on the basis of the model. The result shows that investment in fixed assets has a positive lag effect for economic, and for a long time, can stimulate economic growth. Finally, on forecast analysis of Xiamen's GDP by ARIMA model and transfer function model respectively, it can be obtained that the transfer function model has higher precision of prediction.
