本文厘清了数字反哺的理论渊源和概念维度，并在家庭传播视域下考察其现状及影 响因素。以全国54座城市954个家庭3291位祖孙三代样本的问卷调查数据为基础，我们 在数字接入反哺、技能反哺和素养反哺的三大维度上进行了不同世代的分析与对比。就 反哺现状而言，年轻世代“给出去的反哺”与年长世代“接受到的反哺”大体能达成 共识，但仍有三成左右互相矛盾。在年长世代中，祖代（老年人）虽然在数字媒体的采 纳、使用与素养方面都显著低于亲代（中年人），但他们各维度数字反哺的接受程度都 显著高于亲代。进一步的影响因素分析也印证了上述发现，个体特征上处于弱势（年龄 大、教育程度低、女性、自我效能感低、心理障碍多）但在家庭结构中位居核心（与家 人互动频繁深入且关系亲密）的人越有可能接受数字反哺。

This study examines the theoretical origins and conceptual dimensions of digital back-feeding and explores its overview and influential factors in the perspective of family communication. Based on survey data from 3291 samples of three generations of 954 families from 54 cities of China, we conduct analyses and comparisons between different generations along the three dimensions of digital back-feeding (i.e., access, skill, and literacy). As the data demonstrate, the “back-feeding given” by the young generation and the “back-feeding received” by the old generation are largely consistent, and the rate of inconsistence is about 30%. Among the old generation, the grand parents are signifcantly inferior to the parents in adoption, use and literacy of digital media, but they received signifcantly more digital backfeeding in all three dimensions. This fnding is verifed by further analyses of the in?uential factors of digital back-feeding. Those who are weak in individual characteristics (i.e., older, less-educated, female with low self-effcacy and high psychological concerns) but act a center role in family structure (i.e., interact more frequently, profoundly, and have intimate relations with family members) are more likely to receive digital back-feeding.
