用博弈论方法公平分配流媒体平台版税，解决艺术家收益难题
The Shapley index for music streaming platforms
- 基于合作博弈的谢林值设计新指数，兼顾公平性与可解释性
- 相比行业常用按播放量或用户偏好分配的方式，该指数更符合公平原则
- 适合关注平台收益分配机制、数字版权经济的研究者与从业者
我们研究一种用于衡量音乐流媒体平台中艺术家受欢迎程度的指标。该指标基于合作博弈论中的谢林值，可用于将订阅收入在参与艺术家间进行分配。通过结合多个形式化公理，我们对这一谢林指数进行了特征刻画，使其在理论文献中具有明确定位，可作为目前行业中广泛使用的按比例分配和用户中心型指数的替代方案。
原文摘要 · Abstract (English)
We study an index to measure the popularity of artists in music streaming platforms. This index, which can be used to allocate the amount raised via paid subscriptions among participating artists, is based on the Shapley value, a centerpiece in cooperative game theory. We characterize this Shapley index combining several axioms formalizing principles with normative appeal. This permits to place the index in the literature, as an alternative to the well-known (and widely used in the industry) pro-rata and user-centric indices.
