Risk Amplification Station Transmutation: A Study On Media Information Mechanism Of African Swine Fever Risk Communication

Risk globalization is an established fact caused by increasingly frequent global exchanges.The emergence of new media has reconstructed the media structure,changed the distribution of communication power in risk communication,and led to the evolution of risk society amplification station.This change is the result of the expansion and redistribution of social communication rights,which brings new changes in variables to the social amplification framework of risk.African swine fever risk is a global risk after the reconstruction of the media structure.As the main body of infection is closely related to people's life,it has received great attention at a specific stage and is a risk event worthy of study.Based on the theory of social amplification of risk,this study uses the method of computational communication to analyze the quantitative characteristics of media articles and the information response mode to risk,the theme of media text information in different stages of risk,the similarities and differences between the actual place of risk occurrence and the place of media discussion,and the emotional inclination of text information Through the analysis of five aspects of how to amplify the risk of African swine fever,this paper studies the information mechanism of African swine fever risk communication in China in recent years,so as to explore the impact of the change of risk amplification station variables on the social amplification framework of risk,and provide possible reference for China to deal with the risk communication in the context of new media.It is found that the non-governmental media composed of multiple subjects become the main body of African swine fever risk amplification station in China;the attention modes of official media and non-governmental media are different at different stages of risk,but the quantity and theme of information reflect that there is a certain correlation between them;the proximity of risk affects the media information response and risk perception with a new mechanism;the dissemination of action information is the key of media The government is regarded as the leader to deal with and solve the risk of African swine fever;the risk picture of the media is different from the actual risk,which leads to regional stigmatization;the media's strengthening of the risk signal of African swine fever is mainly affected by proximity and uncertainty,which weakens the risk in the pre outbreak stage,enlarges the risk in the outbreak stage and normalizes the risk in the normalization stage Relatively weakened and maintained at a certain level.Some of the above findings are the result of changes in the pattern of media,while others are the result of China's social operation mechanism.After thinking and discussing the findings,the main conclusions of this study are summarized as follows: proximity affects information response with new mechanism,and "time eliminates space" changes risk perception;multiple subjects participate in risk construction,and dual discourse space brings new challenges to risk communication;media weakens risk with action information,and the role of government in risk is the action subject;media risk map The negative events lead to regional stigmatization;information influences risk amplification by strengthening or weakening risk signals.According to the research conclusions and research purposes,the following suggestions are put forward: strengthen risk monitoring to enhance the initiative of risk response;strengthen interactive communication to reshape the leading role of the official media;strengthen public opinion monitoring to maintain the image of the region in time;build a positive image of the government to play a leading role in risk management.
