摘要翻译：
送礼是一种普遍存在的社会现象，红包作为货币礼物在亚洲国家已有几千年的历史。近年来，通过微信平台，网络红包在中国变得普遍。利用一个由6100万个群组红包和700万用户组成的独特数据集，我们进行了一项大规模的、数据驱动的研究，以了解红包的传播以及红包对群组活动的影响。我们发现，各省之间的现金流与各省GDP排名基本一致，例如，红包从南方用户发送到北方用户。通过区分自发红包和互惠红包，我们揭示了发红包的行为模式：男性、老年人和群内好友较多的人更倾向于自发发红包，而女性、年轻人和群内好友较少的人更倾向于互惠发红包。进一步，我们利用倾向得分匹配研究了红包对群体动力学的外部效应。我们发现，红包增加了群体参与，加强了群体内的关系，这部分解释了发送红包的好处和动机。

一级分类：Computer Science        计算机科学
二级分类：Social and Information Networks        社会和信息网络
分类描述：Covers the design, analysis, and modeling of social and information networks, including their applications for on-line information access, communication, and interaction, and their roles as datasets in the exploration of questions in these and other domains, including connections to the social and biological sciences. Analysis and modeling of such networks includes topics in ACM Subject classes F.2, G.2, G.3, H.2, and I.2; applications in computing include topics in H.3, H.4, and H.5; and applications at the interface of computing and other disciplines include topics in J.1--J.7. Papers on computer communication systems and network protocols (e.g. TCP/IP) are generally a closer fit to the Networking and Internet Architecture (cs.NI) category.

英文摘要：
  Gift giving is a ubiquitous social phenomenon, and red packets have been used as monetary gifts in Asian countries for thousands of years. In recent years, online red packets have become widespread in China through the WeChat platform. Exploiting a unique dataset consisting of 61 million group red packets and seven million users, we conduct a large-scale, data-driven study to understand the spread of red packets and the effect of red packets on group activity. We find that the cash flows between provinces are largely consistent with provincial GDP rankings, e.g., red packets are sent from users in the south to those in the north. By distinguishing spontaneous from reciprocal red packets, we reveal the behavioral patterns in sending red packets: males, seniors, and people with more in-group friends are more inclined to spontaneously send red packets, while red packets from females, youths, and people with less in-group friends are more reciprocal. Furthermore, we use propensity score matching to study the external effects of red packets on group dynamics. We show that red packets increase group participation and strengthen in-group relationships, which partly explain the benefits and motivations for sending red packets.
