中文摘要：

考察三个广受关注的社会事件个案,从情境空间的视角对群体性利他行为的发生机制进行探究。发现情景空间的制度化程度是解释群体性利他行为的关键因素;在特定的情境空间中,施暴者的负面标定、受害者的＂嵌空间＂身份、制度化角色的干预以及旁观者的人口特征等因素都是抑制或催发群体性利他行为的影响变量。

英文摘要：

Based on the case study upon three widely concerned social events,this paper explores the mechanism of mass altruistic behavior.It finds that the degree of institutionalization of textured space is the critical factor to explain the occurrence of mass altruistic behavior.In a specific textured space,perpetrators′ negative labeling,victims′ status in embedded-space,disposal of institutionalized role and demographic feature of bystanders are important explanatory variables,which may restrain or arouse the occurrence of mass altruistic behavior.
