Research On Transgenic Network Public Opinion Analysis And Governance

Transgenic technology has broad development prospect,but it has faced such a situation since its emergence: On the one hand,it is regarded as the commanding height of technology and the focus of modern agricultural technology development by various countries,and has been developed rapidly;On the other hand,it has been accompanied by constant controversy and has maintained a high degree of public opinion for a long time.Starting from the safety of transgenic,it has caused a series of fierce debates,the topic involves various aspects such as economics,politics,and environment.Coupled with the appearance of a series of negative events,which has seriously affected the public's perception and cognition of transgenic.Public opinion is full of irrational remarks,which affects the further development of transgenic and even affects the formulation and implementation of transgenic strategies and policies in China.With the development of the mobile Internet,new media platforms represented by Weibo,We Chat and so on have further broken the time and space limitations of information dissemination,attracted a large number of users,and become an emerging public opinion position.With the help of the network,public opinion increases in geometric multiples and has a greater influence.Network public opinion has become a barometer of social sentiment and public opinion,plays an important role in social governance.The popularity of Genetically modified(GM)public opinion in the network is higher,the participants and topics are wider.Whenever new relevant information appears,each platform will generate a large number of fierce speech.Once it is not guided in time,will lead to the spread of negative emotions,serious or even affect social harmony and stability.Therefore,exploring GM,a highly sensitive and emotional public opinion,and understanding its performance and influencing factors in the network are of great significance for optimizing the environment of GM public opinion,promoting the safety and sustainable development of GM.This paper focuses on the research of GM network public opinion.First of all,the relevant research background,the current research status at home and abroad,research purpose and significance,the main content and methods are expounded,and the possible innovative points of research are proposed.Secondly,the core concepts such as geneticmodification,network public opinion,and emotional tendency involved in the research are defined,to make the research content more clear;and the relevant theoretical basis are explained,the theory of public governance,agenda setting is used to provide theoretical support for the research.Then,the GM network public opinion is explored from both qualitative and quantitative aspects.On the one hand,the causes,manifestations,participants and the main features of public opinion are analyzed.On the other hand,taking Sina Weibo platform as an example to carry on the empirical analysis from the emotional perspective.Collect big data through the Python crawler program,use word segmentation and keyword extraction,topic clustering and sentiment analysis to perform text processing,then through descriptive statistical analysis,comprehensively understand the public opinion sentiment,information dissemination and user characteristics in Weibo.Further exploring the factors influencing public opinion through the multiple logistic regression model,it was found that the variables in the topic type of Weibo,the characteristics of communication effects,the characteristics of text information and the characteristics of comments have different effects on the sentiment of public opinion.Finally,combined with the analysis results,from the perspectives of government behavior and the characteristics of new media on the Internet,countermeasures and suggestions for guiding and governing the public opinion of GM networks are proposed.Improving the environment of GM public opinion requires the joint efforts of the government,various media,opinion leaders and other multi-subjects.In addition,the full text is summarized and prospected.
