This paper introduces constant relative risk aversion utility function to construct a welfare utility model with information consumption growth rate changes, by using the information consumption data of Chinese rural residents during 1993~2011, makes numerical simulation on the welfare effect of rural residents information consumption growth rate changes from overall and income-stratified angle, indicates that information consumption growth rate change has relatively big welfare effect by analysis, i.e., when information consumption growth rate increases 1 percent, per rural household in its unlimited lifetime increases 0.39~17.73 percent information consumption products or service annually, however, when information consumption growth rate decreases 1 percent, per rural household in its unlimited lifetime decreases 0.52~22.28 percent information consumption products or service annually, and meanwhile, the welfare effect of information consumption growth rate changes have obvious group difference and have more significant effect on the rural households with higher income than the rural households with lower income. Thus, China should stably push forward institutional reform to narrow the information consumption gap of the rural households with different income levels while boosting total quantity growth of information consumption of the rural residents.
