【摘要】：社交媒体近年来已成为人们发布和获取信息的重要渠道,其中以新浪微博为典型代表。基于微博平台的信息沟通优势,政务微博平台建设日趋成熟,在各类社会事件和日常事务中成为政府官方机构发布及时信息的有效工具,其中就包括各类自然灾害信息。政务微博平台在灾害管理中体现了较高的信息沟通价值,尤其是在灾害事件的应急处理中,作为应急响应的主体,政务微博信息的发布能够有效满足公众信息需求,促进灾害信息流通。而政府部门作为信息供给方,其灾害信息发布模式是否与公众信息需求与反应相协调会显著影响灾害信息沟通效果,了解灾害情境下政务微博的释放规律、相应的公众关注行为,以及其影响机制有助于充分发挥政务微博平台信息沟通潜能,促进自然灾害信息管理。本文首先选取8个近年来典型的自然灾害事件为研究对象,搜集各灾害事件应对过程中政务微博平台的灾害信息与公众关注数据,通过时间流量变化和信息内容差异两个方面对信息发布模式与公众关注进行分析,并且就政务微博互动性干预策略对公众关注的影响作了进一步考察;后搜集了气象政务微博平台的3452条预警信息与公众关注数据,进行公众关注度的影响因素分析,探究日常灾害管理中特定自然灾害信息的发布模式与公众关注的影响机制。主要结论有:1.突发型与常规型自然灾害事件中政务微博平台信息发布趋势不同,公众关注度亦然;2.不同类型自然灾害事件中政务微博平台信息内容框架不同,常规型侧重监测信息,突发型侧重救援行动信息;3.突发型灾害事件中公众对于灾情汇报信息最为关注,另外公众对于政府责任归因感知程度亦影响其信息关注侧重点;4.与公众的互动干预能显著提高关注度;5.灾害预警信息的关注度受到诸多因素影响,如媒体丰富性与发布时间。
[Abstract]:Social media has become an important channel for people to publish and obtain information in recent years, with Sina Weibo as the typical representative. Based on the advantages of information communication based on Weibo platform, the construction of government Weibo platform is becoming more and more mature, and it has become an effective tool for government organizations to release timely information in all kinds of social events and daily affairs, including all kinds of natural disaster information. Government Weibo platform embodies high information communication value in disaster management, especially in the emergency management of disaster events, as the main body of emergency response, the release of government Weibo information can effectively meet the information needs of the public. To promote the flow of information on disasters. As the information supplier, whether the disaster information release mode and the public information demand and response significantly influence the communication effect of disaster information, and understand the release law of Weibo in the disaster situation. The corresponding behavior of public concern and its influence mechanism are helpful to give full play to the potential of information communication in Weibo platform of government affairs and to promote the information management of natural disasters. This paper first selects 8 typical natural disasters in recent years as the research object, collects the disaster information and the public concern data of the government affairs Weibo platform in the process of each disaster event response. Through time flow change and information content difference, this paper analyzes the mode of information release and public concern, and makes a further study on the influence of government Weibo interactive intervention strategy on public concern. After that, it collects 3452 items of early warning information and public concern data from meteorological government Weibo platform, analyzes the influencing factors of public concern, and probes into the release mode of specific natural disaster information and the influence mechanism of public concern in daily disaster management. The main conclusion is: 1. The trend of publishing information on Weibo platform is different from that of normal natural disasters, and so is the public attention. In different types of natural disaster events, the information content framework of Weibo platform is different, the routine type is focused on monitoring information, and the sudden type is focused on rescue information. The public pays the most attention to the disaster reporting information in the sudden disaster event, and the degree of the public perception of the attribution of government responsibility also affects the focus of its information attention. Interaction with the public can significantly increase attention. The attention of disaster warning information is affected by many factors, such as media richness and release time.
