本研究借用文化反哺概念，將代間家庭的年輕世代願意協助老年世代進行上網，或解決上網所遇到困難的現象，稱為「網路反哺」。本文目的主要在調查代間家庭的大學生對祖父母的網路反哺意願、實踐現況，以及反哺過程實際遭遇的阻礙因素。本研究採用自編之代間家庭網路反哺問卷，並以大學生為研究對象進行調查，總計發出1,200份問卷，回收統計有效問卷1,015份，有效問卷率達85%。經統計分析及討論後獲得如下結論：（一）大學生對於家庭網路反哺的意願有餘但行動不足；（二）大學生偏愛以代理反哺方式進行家庭網路反哺活動；（三）大學生實踐代間家庭網路反哺阻礙之一：上網對祖父（母）產生負面影響；（四）大學生在實踐家庭網路反哺阻礙之二：祖父母輩不想學上網或不需要上網；（五）大學生在實踐家庭網路反哺遇到阻礙之三：學校活動或學業繁重；（六）維持好的關係或定期回家才有實踐家庭網路反哺的可能。最後並提出若干建議作為推動代間家庭網路反哺之參考。

We adopted the cultural feedback concept in this study. In the inter-generational family, the younger generation can assist or help the older generation to access the Internet and solve the difficulties known as ＂digital culture feedback.＂ The purpose of the paper is as follows: (1) to investigate and analyze the desire and practice of digital cultural feedback from the younger generation; (2) to analyze the obstacles of digital cultural feedback from the older generation; For these objectives, a questionnaire survey was conducted. The results showed that: (1) university students have the willingness but lack of action in the family digital culture feedback; (2) university students prefer the way of proxy feedback in family digital culture feedback activities; (3) one of the biggest obstacles encountered by students in the practice of family digital culture feedback is that the internet environment is not suitable for the elderly to learn; (4) one of the biggest obstacles encountered by students in the practice of family digital culture feedback is that older people don't need or want to access the Internet; (5) one of the biggest obstacles encountered by students in the practice of family digital culture feedback is too much school activities and heavy homework; (6) keeping a good relationship or going home periodically provides family digital culture feedback. Some suggestions were offered.
