| Abstract: | A prediction method of per capita net income of rural residents based on grey theory is studied. In this paper an ordinary GM （ 1,1 ） model group with different dimension is established and the simulating rela- tive errors are calculated in order to choose the optimal basic GM （ 1,1 ） model. Based on this a grey renewal GM （ 1,1 ） predicting model is constructed to forecast per capita net income of rural residents in Shaanxi prov- ince. This forecasting method could effectively integrate new information and make up for the shortage of ordi- nary GM （ 1,1 ） model. The computational results of example show that the forecasting result of grey renewal GM （ 1,1 ） model is accurate comparatively. |
