中文摘要：
社交网络中单纯的线上交互已经无法满足用户的需求,一些新型的融合用户线上和线下体验的社交网络服务开始出现.文中基于国内知名的豆瓣同城活动网站,探索用户线下活动和线上行为的特点,进而研究线上线下的社交影响.通过对44天内采集到的6545个活动和近10万次参与用户的统计分析,结合对活跃用户的问卷调查和真实数据实例验证两种方式,发现线上社交影响在一定条件下推动了活动的开展,而活动的开展对用户线上社交关系的建立也有一定的促进作用.该研究有助于理解基于线下活动的社交网络及其参与者的行为特点,并验证了线下活动与线上关系的相互影响,该研究成果对于广告投放、活动组织和好友推荐等应用有重要现实意义.
