农业农村信息化是创新驱动农业农村现代化、带动农业增效与农民增收的先导力量与重要引擎。基于2000—2019年全国31个省域的面板数据，视国家农村农业信息化示范省建设试点项目的开展为准自然实验，运用多期DID模型评估农业农村信息化政策的农民增收效应。研究结果表明：农业农村信息化政策对农民人均可支配收入具有显著而稳健的提升作用；农业农村信息化的农民增收效应存在区域异质性，即西部地区农民增收效应显著强于中部与东部地区；农业农村信息化政策主要通过提供满足农民需求的信息技术和服务，促进农民增收。对此，应该进一步健全政策体系、明确政策导向、抓好政策执行、注意政策倾斜，以提升新时期农业农村信息化政策的农民增收效应。

Agricultural and rural informatization is the leading force and important engine to drive agricultural and rural modernization, promote agricultural efficiency and increase farmers ' income. Based on the panel data of 31 provinces across the country from 2000 to 2019, and taking the construction pilot project of the national rural and agricultural informatization demonstration province as a quasi-natural experiment, the multi-period difference-in-differences model is used to evaluate the income increase effect of agricultural and rural informatization. The results show that the implementation of agricultural and rural informatization policy can significantly improve the per capita disposable income of rural residents. The effect of agricultural and rural informatization on farmers' income has regional heterogeneity, which is embodied in the promotion effect of agricultural and rural informatization policy in the western region on farmers' income significantly stronger than that in the central and eastern regions. Therefore, we should further improve the policy system, clear the policy direction, do a good job in policy implementation and pay attention to the policy tilt, so as to enhance the effect of the agricultural and rural informatization policy on increasing farmers' income.
