【摘要】 [目的 /意义]探究社交媒体用户隐私策略的选择与影响，明晰信息披露不同阶段用户隐私管理策略选择的差异，为加强用户个人隐私保护及完善社交媒体平台隐私设置提供参考。[方法 /过程]基于沟通隐私管理理论，将社交媒体平台用户的隐私管理策略划分为披露前的预防策略、披露阶段的审查策略以及披露后的纠正策略，通过准实验方法采集数据，采用2×2析因设计方法分析探究隐私管理策略的选择差异与影响机制，并结合路径分析方法对社交意识、隐私关注、自我披露和隐私管理策略之间的关系进行实证检验。[结果 /结论 ]实验结果表明，感知隐私风险和感知隐私控制对隐私管理策略的选择存在显著的主效应和交互效应，隐私关注程度高的用户，倾向于披露较少的个人信息，而自我披露经历较丰富的用户，则采取较为宽松的隐私管理策略。研究结果可为社交媒体平台依据用户的心理和认知特征提供灵活丰富的隐私管理策略与加强隐私保护提供理论参考和实践启示。更多还原

【Abstract】 [Purpose/Significance] This paper aims to explore the selection and influence of privacy strategies for social media users, and clarify the differences in user privacy management strategy choices at different periods,to provide reference for strengthening user personal privacy protection and improving privacy settings on social media platforms. [Method/Process] Based on the communication privacy management theory(CPM), the paper divided privacy management strategies on social media platform into prevention strategies before disclosure, review strategies during disclosure, and correction strategies after disclosure. Through quasi-experimental method, it explored the influence of different perceived privacy risk levels and perceived privacy control degrees on users’ privacy management policy selection. With path analysis, it empirically tested the relations between social awareness,privacy concerns, self-disclosure, and privacy management strategies. [Result/Conclusion] The results show that perceived privacy risk and perceived privacy control have a significant effect and interaction effect on the selection of privacy management strategies. Users with a high level of privacy concern tend to disclose less personal information, while users with more self-disclosure experience adopt more lenient privacy management strategies. It provides theoretical references and practical implications for how social media platforms can provide flexible and rich privacy management strategies based on users’ psychological and cognitive characteristics, thereby strengthening privacy protection.更多还原
