In this paper, the intervention analysis model has been generalized in the sense that its intervention function either being a jumping function used to describe the continuing intervention or a unit impulse function used to describe the transient intervention has been replaced with a unified function, , which represents an intervention process, denotes the amplitude (or strength) of the impact of intervention events at intervention time, denotes the decay factor of continuing process. Applying the generalized model to predict the Gross Domestic Product (GDP) of Hainan province from 1989 to 2016, as a Government intervention was introduced in 2010, results in a 60% of improvement in terms of the Root Mean Square Error (RMSE), when compared with the original model.
