目前,国内学者大多从网络传播形态及其传播特质的角度,研究网络空间对于公共领域的建构意义。本文试从卡斯特的网络社会理论入手,讨论当网络成为定义某种空间概念的新兴力量时,公共领域之于网络空间的实现可能性,即在网络空间作为流动空间、以议题为节点、促进社会认同这些方面对于公共领域实现的意义所在。 At present, most scholars in China study the constructional significance of cyberspace in the public domain from the perspective of the form of network dissemination and its transmission characteristics. This paper tries to start with Custer’s social theory of network to discuss the possibility of realization of the public sphere in cyberspace when cyberspace becomes an emerging force that defines some kind of spatial concept, that is, cyberspace is used as a mobile space, Promote social acceptance of these aspects of the public sphere of significance.
