Optimal Model of Forecasting the Per Capita Disposable Income of Urban Residents

The per capita disposable income of urban residents reflects the people's living standards and spending power. In this paper, we study the problem of forecasting the per capita disposable income of urban residents, and present an optimization forecasting model based on the grey system theory, i.e., an improved GM(1,1) model with the power function transformation. Moreover, an application example of forecasting the per capita disposable income is provided to highlight the implementation, practicality, and effectiveness of the presented model.
