更大未必更好：P2P网络最优成员规则的实证分析
Bigger May Not Be Better: An Empirical Analysis of Optimal Membership Rules in Peer-To-Peer Networks
摘要：
对等网络将成为消费者信息产品越来越重要的分销渠道，并可能在公司内部的信息分销中发挥作用。我们的研究分析了这些网络的最佳成员规则的积极和消极的外部性，额外的用户施加在网络上。使用从六个最大的OpenNap-based网络收集的数据集，我们发现，用户施加一个积极的网络外部性的基础上，他们提供的内容的可取性和负的网络外部性的基础上，他们对网络的要求。此外，我们发现，额外的用户的边际价值是下降的，边际成本是增加的现有用户的数量。这表明，多个小型网络可以比单个单片网络更有效地服务于用户社区，并且网络运营商可能希望专注于其内容并基于容量约束和用户内容期望来限制成员资格。
英文摘要：
Peer to peer networks will become an increasingly important distribution channel for consumer information goods and may play a role in the distribution of information within corporations. Our research analyzes optimal membership rules for these networks in light of positive and negative externalities additional users impose on the network. Using a dataset gathered from the six largest OpenNap-based networks, we find that users impose a positive network externality based on the desirability of the content they provide and a negative network externality based on demands they place on the network. Further we find that the marginal value of additional users is declining and the marginal cost is increasing in the number of current users. This suggests that multiple small networks may serve user communities more efficiently than single monolithic networks and that network operators may wish to specialize in their content and restrict membership based on capacity constraints and user content desirability.
