【Purpose/significance】The information capability is the direct embodiment of the endogenous motive force of farmers' infor⁃

mation income increase, and contributing to the healthy development of digital rural revitalization.【Method/process】Based on the sci⁃entific definition of information capability, this paper uses DID and DDD model to evaluate the information capability and its compo⁃nents of farmers since the policy of network precision poverty alleviation in our country.【Result/conclusion】the results showed that the information capability, information awareness capability, information searching capability, information judgment capability and infor⁃mation using capability of the registered card poverty alleviation households increased by 7% , 17.3% , 8.9% , 3.9%and 6.6%, but the information mining capability is not significant. According to the analysis of heterogeneity, the information capability, information awareness capability and information mining capability of male group is stronger than that of female group; The older they are, the weaker their information searching capability and using capability is, but their information judgment capability is significantly stron⁃ger; Contrary to common sense, the information mining capability is stronger with smart terminals and home internet access, but other capabilities are weaker; The higher the per capita income, the stronger the information capability; The more the household labor force, the weaker its information capability, information searching capability and information using capability are; The information capability of the northwest region is relatively weaker; The higher the level of regional development, the stronger the information capability, infor⁃mation awareness capability and information using capability; The greater the regional platform support, the stronger the information searching capability and information using capability.【Innovation/limitation】This paper discusses the information ability of farmers and its components, and makes an empirical evaluation but the conduction relationship between the components needs to be further studied.
