构建农户数字素养-行为响应-粮食生产脆弱性的三位一体分析框架，理论探析数字素养对农户粮食生产脆弱性的影响，并采用2020年中国乡村振兴综合调查数据（CRRS）进行实证分析，结果表明：农户数字素养提高可以降低粮食生产脆弱性，进一步用工具变量估计、倾向得分匹配、遗漏变量检验后结论依然成立；异质性检验结果表明，中青年和较高学历的户主家庭具有显著性行为响应效果；中介效应表明，农户数字素养通过资本配置效率提高、生产行为创新、市场空间拓宽，降低粮食生产脆弱性。

By adopting the 2020 China Rural Revitalization Survey (CRRS), a triadic analysis framework (digital literacy+behavior response+grain production vulnerability) was constructed, and the influence of digital literacy on the vulnerability of farmers’ grain production was researched empirically. The study shows that enhanced digital literacy of farmers could significantly reduce grain production vulnerability, and the conclusion still stands after estimating instrumental variables, matching propensity scores and verifying missing variables. Heterogeneity test results demonstrate that young and middle-aged farmers and farmers with a higher educational background have significant behavioral response effect. Mediation analysis further reveals that enhanced digital literacy could reduce grain production vulnerability by improving the capital allocation efficiency, innovating production behavior, and expanding market space.
