“微博实名制”政策自出台起就引发了社会各界的热议。其作为一种政策工具,一方面减少了虚假信息的传播,降低了人际交往成本,保证了公共话语平台的健康发展,另一方面又因不利于公众真实意愿表达,信息安全和认证方式不受信任而饱受争议。但总的来看,如果能够给微博实名制政策配套以相应的制度体系与技术措施,这一政策对公共领域建构来说依然利大于弊。 “Weibo real-name system ” policy since its introduction has triggered a hot debate of all sectors of society. As a policy tool, on the one hand, the spread of false information is reduced, the cost of interpersonal communication is reduced, the sound development of public discourse platform is ensured, and on the other hand, it is not conducive to expressing the true wishes of the public and the information security and authentication methods are not trusted Ren and controversial. However, on the whole, this policy will still outweigh the disadvantages of constructing the public domain if it is able to support the micro-blog real-name system policies with corresponding system and technical measures.
