引入常数相对风险规避效用函数，构建信息消费增速变动的福利效应模型，采用1993-2011年中国农村居民信息消费数据，从总体和收入分层视角对农村居民信息消费增速变动的福利效应进行数值模拟，分析表明信息消费增速变动具有相当大的福利效应：信息消费增速提升1％，相当于在农户无限生命期界内每年增加0．39％～17．73％的信息消费产品或服务；而信息消费增速下降1％，相当于在其无限生命期界内每年减少0．52％～22．28％的信息消费产品或服务。同时，信息消费增速变动的福利效应具有明显的群体差异性，对高收入农户的影响比对低收入户的影响更为显著。因此，在促进农村居民信息消费总量增长的同时，应稳步推进制度改革，从而缩小不同收入水平农户间的信息消费鸿沟。
引入常數相對風險規避效用函數，構建信息消費增速變動的福利效應模型，採用1993-2011年中國農村居民信息消費數據，從總體和收入分層視角對農村居民信息消費增速變動的福利效應進行數值模擬，分析錶明信息消費增速變動具有相噹大的福利效應：信息消費增速提升1％，相噹于在農戶無限生命期界內每年增加0．39％～17．73％的信息消費產品或服務；而信息消費增速下降1％，相噹于在其無限生命期界內每年減少0．52％～22．28％的信息消費產品或服務。同時，信息消費增速變動的福利效應具有明顯的群體差異性，對高收入農戶的影響比對低收入戶的影響更為顯著。因此，在促進農村居民信息消費總量增長的同時，應穩步推進製度改革，從而縮小不同收入水平農戶間的信息消費鴻溝。

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.
