【Abstract】 Based on the data analysis of urban-rural income gap in Anhui Province from1998 to 2017,a multivariate regression model,aquadratic exponential smoothing model and an ARIMA(1,1,0)model were established.Based on this,an IOWGA operator based on closeness was constructed.The combined forecasting model predicts the urban-rural income gap in Anhui Province from 2018 to 2020.The forecast results show that the urbanrural income gap in Anhui Province will continue to expand,and the average annual growth rate in the next three years is about 5%.更多还原
