在这项研究中，各种形式的数据共享公理化。提出了一种研究竞合，特别是数据共享竞合的新方法。观察到信号依赖于动作的贝叶斯博弈问题，并提出了一种处理这种依赖的方法。我们专注于固定路线的过境服务市场。首先建立了一个离散模型，分析了存在外部性效应时寡头垄断公交市场的数据共享合作竞争。给定一个固定的数据共享结构，贝叶斯博弈被用来捕捉不确定性下的竞争，而联盟形成模型被用来确定稳定的数据共享决策。提出了一种研究有效市场的新方法--复合联盟法。提出了一种替代的连续模型，以处理大型网络使用模拟。我们将这些模型应用于各种类型的网络。实验结果表明，完全信息可能导致完全自私。分享更多的数据并不一定能改善所有群体的过境服务，至少如果过境运营商仍然不合作的话。服务的互补性并不一定能保证一个大的数据共享联盟。这些结果可以为政策制定提供见解，例如城市当局是否应该在运营商之间合作的情况下实施强制性数据共享沿着，或者建立一个自愿的数据共享平台。
In this study, various forms of data sharing are axiomatized. A new way of studying coopetition, especially data-sharing coopetition, is proposed. The problem of the Bayesian game with signal dependence on actions is observed; and a method to handle such dependence is proposed. We focus on fixed-route transit service markets. A discrete model is first presented to analyze the data-sharing coopetition of an oligopolistic transit market when an externality effect exists. Given a fixed data sharing structure, a Bayesian game is used to capture the competition under uncertainty while a coalition formation model is used to determine the stable data-sharing decisions. A new method of composite coalition is proposed to study efficient markets. An alternative continuous model is proposed to handle large networks using simulation. We apply these models to various types of networks. Test results show that perfect information may lead to perfect selfishness. Sharing more data does not necessarily improve transit service for all groups, at least if transit operators remain noncooperative. Service complementarity does not necessarily guarantee a grand data-sharing coalition. These results can provide insights on policy-making, like whether city authorities should enforce compulsory data-sharing along with cooperation between operators or setup a voluntary data-sharing platform.
