| The essay positions the Micro-Blogging-the most representative medium tool into the study field of communications, sociology, and cultural studies. Meanwhile, it combines the most influential public social events in recent years, and explains the reality and the influence of mechanism public opinion in Micro-Blogging by quantitative and qualitative research. Further more, it analyses the appearance of discourse for social public events in reality and people’s network, in order to discuss the speed of trends and regulations of Micro-Blogging. In addition, it puts forward the construction of media public area, and to build a harmonious society of the spirit of the citizens by reveal the conception and outlook, which provided a participation of theoretical model for Micro-Blogging in social public events.First of all, Micro-Blogging is mass communication, also interpersonal communication, both macro-public dissemination of information, but also microscopic information, ideas and emotional communication between individuals. In China, rapidly developing and in the gaming of traditional and modern, Micro-Bloggingging’s open, sharing, and personalized features authorizes voice to the public, being a dynamic information dissemination network, it is given to carrying different interests the possibility of the main discourse because of its unique diffusion structure. In the series events, such as Wenzhou CRH accident, Guomeimei event, Handy shot to rescue the children beggars, Micro-Blogging played an important role. It empowers the public to communicate, agenda-setting, changes the traditional info communication environment, promotes the events directly with the social action. Micro-Blogging reflects the reality, also the public opinions.Also, what we should point out is, there are so many disadvantages of Micro-Blogging in the spread process of public events. The umcertainty of participants makes the information being largely produced that caused the fragmentation of information, also "Information-mazing" and "Information Overloading". The fragmented information and their audiences which were very much aligned with the characteristics of postmodern culture, but since then, the spread of Micro-Blogging that being lack of integrity and systemic. Meanwhile, people can easily get lost while they are traveling between the world of social reality and the virtual internet. The grass-roots spirits of Micro-Blogging eliminate the rules and the identity. However, Micro-Blogging is also characterized by irrationalism which brought increasingly polarized opinion and false information. People are pushed to the activity of unconscious population celebration through the subversion of great sensation. Consequently, it raised the high spread of uncommon and irrational information either. Besides, the influence and restriction of economic and political power can not be ignored by Micro-Blogging. Until now, Micro-Blogging still can not develop a reasonable and effective business model which made it had to be the product appendages of economic capital. So, once the social pubic events related to some sensitive topic discussion that would be result from the collision and conflict with the policy audit by relevant government departments.Finally, we believe that with the benign guidance and development, Micro-Blogging will make the construction of public domain of media to reality. The integration of the advantages of neutrality, objectivity and authority of traditional media, Micro-Blogging will better enable dissemination and interpretation of the information of social public events. The comparatively freedom and deep discussion about the social issues and the participation of all the people on Micro-Bloggings satisfies the inner demands in public. In the meantime, the government departments at all levels have opened Micro-Blogging. The participation of the authority is also given Micro-Blogging legitimacy on the authorities, that has become the power promoting the development of social public affairs and political democratization process. Being the public in Micro-Blogging age, the public of must raise new media literacy, develop critical thinking skills and civic spirit, to further promote the healthy development of the Micro-Blogging, and promote social progress. |
