风险沟通视角下突发事件融媒体信息生态系统要素关系识别研究

Research on the Identification of Element Relationships in the Convergence Media Information Ecosystem of Emergencies from the Perspective of Risk Communication

[目的/意义]风险沟通视角下突发事件融媒体信息生态系统构成要素的识别、要素的因果序与关键性的识别有助于该系统进行有序、分级优化,助力应急工作。[方法/过程]探讨突发事件融媒体信息生态系统结构框架,并识别其构成要素,采用模糊集理论—DEMATEL研究方法,计算各构成要素“四度”,探讨突发事件融媒体信息生态系统构成要素的因果序及关键性,并以此为依据对构成要素进行聚类分析。[结果/结论]研究识别出38个构成要素中包含17个原因要素、21个结果要素;构成要素中包含14个关键要素;聚类分析将构成要素划分为6级。研究结果为突发事件融媒体信息生态系统有序、分级优化提供参考依据。

[Purpose/Significance]From the perspective of risk communication,the identification of the constituent elements of the emergency convergence media information ecosystem,the causal sequence and criticality of the elements are helpful to optimize the system in an orderly and hierarchical manner,and help the emergency response work.[Method/Process]This paper discussed the structural framework of the emergency convergence media information ecosystem,identified its constituent elements,calculated the“four degrees”of each component by using the Fuzzy Set Theory—DEMATEL research method,discussed the causal order and criticality of the constituent elements of the emergency convergence media information ecosystem,and conducted cluster analysis on this basis.[Result/Conclusion]The study identifies 17 cause elements and 21 effect elements among the 38 constituent elements,and 14 key elements among the constituent elements,and the cluster analysis divided the constituent elements into six levels.The research results provide a reference for the orderly and hierarchical optimization of the emergency convergence media information ecosystem.
