探究跨文化传播视角下多语言用户信息分享行为影响因素组态，有助于提升其跨文化信息分享意愿，促进跨文化信息资源流动。文章以多语言用户为对象，围绕信息主体、内容、技术和环境四个维度提取研究变量。通过问卷调查收集数据，并采用模糊集定性比较分析和回归分析，识别多语言用户信息分享行为影响因素的关键组态。研究发现，跨文化传播视角下多语言用户信息分享行为发生的必要条件为社交环境，产生显著正向影响的关键因素包括语言环境、文化环境、社交环境、系统质量，且核心影响因素组态主要有三种类型即多元环境导向型、文化环境沉浸型和语言环境敏感型。研究结果不仅验证了信息分享行为多维度因果结构的基本稳定性，而且揭示了其在动态变化过程中特定因素的可变性和情境依赖性特征。这些发现既丰富了对于跨文化传播视角下信息分享行为影响机制的理论认识，也为制定跨文化传播策略提供了实践参考依据，可针对性地强化或调整干预措施以优化多语言用户的信息分享效果。

This study aims to explore the configuration of factors influencing information sharing behavior among multilingual users from the perspective of cross-cultural communication, with the goal of enhancing their willingness to share information across cultures and promoting the flow of intercultural information resources. This study selects multilingual users as the subject and extracts research variables based on the dimensions of information subject, content, technology, and environment. Data were collected through a questionnaire survey and analyzed using fuzzy-set qualitative comparative analysis and regression analysis to identify the core configurations of factors affecting information sharing behavior. It is found that the social environment is the necessary condition for the occurrence of information sharing behavior, and significant positive influence relationships are found with language environment, cultural environment, social environment, and system quality. The configurations of influencing factors are categorized into three types. The findings not only verify the stability of the multidimensional causal structure of information sharing behaviors but also uncover the variability and context-dependent characteristics of specific factors in their dynamic process. These discoveries contribute to theoretical insights into the mechanisms influencing information sharing behaviors from the perspective of cross-cultural communication and provide practical references for the development of cross-cultural communication strategies. Interventions can be tailored or adjusted accordingly to optimize information sharing effects among multilingual users.
