| 目的 在“健康中国”战略深入实施背景下，推进食物系统转型对改善居民膳食健康具有重要意义。方法 文章基于安徽、湖南和广西3省区934份实地调查数据，综合运用PLS-SEM、Ordered Logit等模型探究了智能终端使用对自留口粮农户膳食健康意识的影响，并进一步揭示这种意识向健康型食物系统转型实践即绿肥稻作系统采纳行为转化的机理。结果 （1）智能终端使用可以通过消除信息不对称，对农户绿肥稻作系统价值认知、口粮健康感知和健康关注程度具有正向强化作用；（2）口粮健康感知与健康关注可分别与绿肥稻作系统价值认知构成链式中介因子，在智能终端使用和采纳行为之间发挥中介作用。结论 应通过进一步提高智能终端在农村的普及率、增加绿肥稻作系统的在线曝光率来推进绿肥稻作系统在中国南方稻区的推广扩散，并注重改善农户的采纳持续性和采纳质量，以改善农村居民膳食健康。 |

| Abstract: |
| Under the background of the in-depth implementation of “Healthy China” strategy, it is of great significance to promote the transformation of food system to improve residents' dietary health. Based on 934 field questionnaires from Anhui, Hunan and Guangxi provinces, the PLS-SEM model and Ordered Logit model were used to explore the effects of intelligent terminal use on the dietary health awareness of self-ration farmers, as well as the mechanism of the transformation of this awareness into a practice of food system transformation, namely the green manure-rice cropping system adoption behavior. Results showed that: the use of intelligent terminal had a positive effect on farmers' value cognition of green manure-rice cropping system, food health perception and health concern degree by eliminating information asymmetry; food health perception and health concern degree formed chain mediators with the value cognition of green manure-rice cropping system, respectively, and played a mediating role between intelligent terminal use and adoption behavior. Therefore, it is suggested that the popularization of green manure-rice cropping system in southern China should be promoted by further increasing the penetration rate of intelligent terminals in rural areas and increasing the online exposure rate of the innovative farming system. Besides, attention should be paid to improving the sustainability and quality of adoption of farmers, so as to improve the dietary health of rural residents. |
