中文摘要：

为探究多元社会认同如何通过群体情绪、自我和群体效能路径，影响现实或网络集体行动参与，研究者分别以中日撞船事件、利比亚事件和就业性别歧视现象为背景蓝本，开展问卷调查和实验研究，结果发现：群体愤怒情绪主要对现实集体行动有显著影响，效能感对现实和网络集体行动皆有显著影响；与事件相关的、更大范畴的社会类别认同，通过情绪路径或效能路径影响集体行动参与，与集体行动组织方的认同则只通过效能路径影响集体行动参与；两类社会认同与两条路径之间是调节而非中介关系。不同事件背景与不同行动场域下的综合分析表明网络集体行动参与决策更具工具理性特征。

Social identity, group-based emotions and efficacy are three major social psychological factors that affect people＇s participation in a collective action. Previous researches, focusing largely on the disadvantaged groups, examined a single factor at a time and/or explored the relationships among these factors in the offiine collective action.

Both surveys included demographics in the first part, followed by a questionnaire on different social identities, group-based emotions and efficacies. Study 3 was an experiment 135 female undergraduates were randomly assigned to three different conditions, female identity primed group, school identity primed group and the control group. Participants then completed a questionnaire on their attitudes toward potential gender discriminations faced by job applicants. Data was collected and analyzed using SPSS 13.0 and Lisrel 8.70. Results indicated that group anger had a significant positive effect on offline collective action participation; and efficacy had a significant positive effect on both offline and online collective action participation. The above effects were further moderated by different social identities. Specifically, identification with a large social category of event affected behavior tendency by moderating emotional path （and rational path
