互联网与“观念市场”
The Internet and the Marketplace of Ideas

摘要 在有关表达自由以及媒介责任的论述中，一直存在所谓“观念市场”（marketplace of ideas）的类比，它借用了经济学上的自由市场概念，在这样的一个市场中，真理和谎言相互竞争，人们期待前者终会战胜后者。观念市场的模式不乏天真和误导，然而，从另一角度看，该模式也有其有力的地方，因为它强调表达自由的重要性，以及信息在观念市场中自由交换所带来的益处。本文通过梳理互联网传播的流变，讨论观念市场在互联网语境下是否适用，以及大规模参与对观念市场的影响。

This paper tries to put "marketplace of ideas"in the Internet context, to see its applicability in the new information environment, as well as the impact of large-scale participation upon the concept
