基于博弈分析的网络版权保护研究

Research on the Protection of Network Copyright Based on Gambling Analysis

网络版权保护旨在权衡网络版权利益相关方的公平利益,定价策略方面利用网络外部性原理和数字产品的特征进行合理定价,网络版权利益的分配策略可以分为两种情况:一种是在作者未申请版权保护情况下,网络版权保护策略达不到"帕累托最优"状态;另一种在有网络版权的情况下,版权利益分配实质上是一个关于作者、出版商和用户的三阶段博弈模型。因此,作者是否创作与出版商是否出版取决于他们对收益回报的预期,用户是否盗版取决于盗版带来的风险损失与购买正版之间的成本估量。

Netword copyright protection is to balance the benefits of copyright beneficiary.Price strategy is that to use principles of network externality and characters of digital products to price reasonable.The strategy of benefits distribution is divided into two aspects：One is under the condition of lacking protection of network copyright,in which the strategy can not achieve the Pareto＇Optimality.The other is actually a three-stage game model about authors,publishers and users.As a result,whether authors to create or not and publishers to publish of not depend on the expecting rewards,and whether users to pirate or not depend on estimating between risk loss and purchasing cost.
