| By using the data concerning China's urban-rural residents' income gap from 1978 to 2010, this paper mainly researches the application of several kinds of models in predicting China's urban-rural residents' income gap. By conducting empirical analysis, we establish ARIMA prediction model, grey prediction model and quadratic-polynomial prediction model and conduct accuracy comparison. The results show that quadratic-polynomial prediction model has excellent fitting effect. By using quadratic- polynomial prediction model, this paper conducts prediction on trend of China's urban-rural residents' income gap from 2011 to 2013, and the prediction value of income gap of urban-rural residents in China from 2011 to 2013 is 14 173.20, 15 212.92 and 16 289.67 yuan... |
