The Impact of Subscription Reciprocity on Charitable Content Creation and Sharing: Evidence from Twitter on Giving Tuesday
研究推特上“给予星期二”慈善运动中，用户关注的对象（互惠与非互惠）如何影响其创作和分享慈善内容，发现互惠关注者促进创作，而非互惠关注者更促进分享。
Social broadcasting sites have grown from an information diffusion channel to a public medium that facilitates public conversations of charitable social movements. Two mechanisms foster user participation in charitable social movements: content creation and content sharing. Users can create original content to express their attitude of giving and promote their most valued nonprofit organizations, enriching the depth of the conversation. They can also share others’ content to expedite the diffusion of high-quality content, expanding the breadth of the discussion. This paper investigates the impact of reciprocal and nonreciprocal followees (i.e., a followee is an account to which other users subscribe) on followers’ decisions to create and share content. Analyzing the charitable movement of Giving Tuesday on Twitter, we find that original charitable content creation is prompted by reciprocal followees’ participation but not nonreciprocal followees’ participation in this movement. We also find that charitable content sharing is evoked by both reciprocal and nonreciprocal followees, with nonreciprocal followees having a greater impact. We discuss the theoretical and practical implications of these findings.
