风险沟通中数字赋能的不对称放大效应——基于“两微一抖”平台的疫情信息传播图谱分析

Asymmetric Amplification Effect of Digital Empowerment in Risk Communication:Analysis of Epidemic Information Transmission Map Based on the Data from“WeChat,Weibo and Tiktok”

风险沟通是公共安全治理模式转型的关键环节,而当前数字赋能已广泛应用于风险沟通过程。数字赋能会不会放大风险沟通中信息传播和获取的不对称性?从公共安全治理角度该如何回应?基于微信公众号、微博、抖音三个新媒体平台疫情风险防控信息的传播数据,运用Gephi软件绘制传播图谱,验证了风险信息获取的不对称放大现象。研究发现,数字赋能风险沟通的不对称放大以风险信息不对称为前提,通过技术工具、个体选择和风险认知三方面催化,形成了信息传播和获取的不对称放大效应。并在政策导向、治理工具与扩散路径等方面就如何保障信息公平提出了政策优化建议。

Risk communication is a key link in the transformation of public security governance model,and digital empowerment has been widely used in the process of risk communication.Will digital empowerment amplify the asymmetry of information transmission and acquisition in risk communication?How should the public security governance respond to this asymmetric amplification?Based on the data of epidemic risk prevention and control information transmission on three new media platforms,i.e.,WeChat,Weibo and Tiktok,the paper uses Gephi software to draw the transmission map,and verifies the asymmetric amplification of risk information acquisition.It is found that the asymmetric amplification of risk communication of digital empowerment is on the premise of the asymmetry of risk information,which forms the asymmetric amplification effect of information transmission and acquisition through the catalysis of technical tools,individual choice and risk perception.In addition,the paper puts forward policy optimization suggestions on how to ensure information equity in terms of policy orientation,governance tools and diffusion paths.
