To analyze rural residents’ income growth in Heilongjiang province, the “quasi-stepwise regression” variable selection method is proposed. This method is based on the regression estimate of minimum sum of absolute errors. In its application to rural resident revenue forecast, household business revenue model and wage revenue model are established. The total relative error of the fitted model is about 8 %. According to these models, factors affecting rural resident revenue are analyzed, and some proposals are given for the increase of rural resident revenue.
