明晰数字技术影响农户生计策略选择行为的内在动力机制，对于合理引导其生计策略选择，提高数字技术对乡村建设的支持作用具有重要意义。本文通过构建数字技术、心理状态与农户生计策略选择行为的供给—需求理论框架，基于2018年中国家庭追踪调查(CFPS)3 422份农户样本数据，采用K-means聚类分析、工具变量法、Logit回归分析以及空间差异性分析探究数字技术、心理状态与农户生计策略选择行为之间的关系。研究表明：(1)数字技术使用有助于提升农户非农化生计策略的选择意愿。(2)因循守旧的传统心理与风险规避心理对数字技术和农户生计策略选择行为之间的关系有显著负向调节作用；而农户社会不公感知程度强化了数字技术对其非农化生计策略选择行为的促进作用。(3)政府在强化农村基站建设以及加速宽带提速降费改革的同时，应配合技术培训机制建设，提高农户信任水平，降低其心理状态变化的负面作用，从供需两方面共同提升数字技术对农户合理生计策略选择的支持作用。

Clarifying the internal dynamic mechanism of digital technology influencing the choice of farmers' livelihood strategies is of great significance for reasonably guiding their livelihood strategy selection and improving the supporting role of digital technology in rural construction. Based on the data of 3 422 farmer samples in the 2018 China Family Panel Studies(CFPS), the relationship between digital technology, psychological state and farmer livelihood strategy selection is explored by K-means cluster analysis, instrumental variable method, Logit regression analysis and spatial difference analysis. Studies have shown that:(1)The use of digital technologies can help improve farmers' willingness to choose non-farm livelihood strategies.(2)The relationship between traditional psychology and risk aversion psychology on digital technology and farmers' livelihood strategy selection behavior has a significant negative moderating effect.Farmers' perception of social injustice strengthens the role of digital technology in promoting the choice of their non-farm livelihood strategies.(3)While strengthening the construction of rural base stations and accelerating the reform of broadband speed and fee reduction, the government should cooperate with the construction of technical training mechanisms to improve the trust level of farmers, reduce the negative effects of changes in their psychological state, and jointly enhance the supporting role of digital technology in the choice of reasonable livelihood strategies for farmers from both the supply and demand sides.
