随着互联网的发展,微博等新媒体异军突起,便捷的操作、即时的传播为公民参政、民主表达、舆论监督开辟了新的渠道。然而,由于网络的虚拟和匿名性、网民自律意识的缺乏、监管机制的不到位,网络言论处于一种开放无序的自由状态,致使网络舆论危机频发。本文在分析微博条件下网络舆论传播的新特点基础上,通过案例剖析深入探讨了微博对网络舆论危机产生的正负影响,展望了微博在网络治理方面的发展前景。 With the development of the Internet, new media such as Weibo have emerged in the wild. Convenient operation and instantaneous communication have opened up new channels for citizen participation in politics, democratic expression and public opinion supervision. However, owing to the virtual and anonymity of the Internet, the lack of awareness of Internet users’ self-discipline and lack of regulatory mechanisms, the online speech is in an open and disorderly state of freedom, resulting in frequent cybercrime crises. On the basis of analyzing the new features of the internet public opinion dissemination under Weibo, this article explores the positive and negative impact of Weibo on the internet public opinion crisis through case analysis, and looks forward to the development prospects of Weibo in network governance.
