协调问题是社会生活中普遍存在的问题，学者们将其抽象成协调博弈。协调博弈具有多个严格的纳什均衡，且这些均衡可形成帕累托序，因而存在效率极低的均衡。学者们利用各种博弈模型进行实验，研究出影响均衡的因素，试图促进协调的成功。研究发现：推举领导者，控制群体规模，进行局部互动，引进激励和惩罚措施等，都有助于均衡向高效率发展，从而促进协调的成功。 本文以Van Huyck的最弱链博弈实验为基础，旨在研究不同信息反馈量对协调博弈结果的影响。通过实验数据的对比，分析基础信息反馈以及大量信息反馈（文中定义为全信息反馈）条件下协调博弈的最终结果。结果表明，其他条件不变时，增强信息反馈有助于推动均衡向高水平发展，同时也使协调的成功率大大提升。

In social life , the problems of coordination exist everywhere. Scholars make them an abstract model called coordination game. A coordination game has multiple Nash equilibrium , which can form a Pareto order. Thus, it is quite difficult to get ideal results that indicate successful coordination. Scholars experiment with various game models to study the factors that affect the result and to promote coordination. Researches find that it is helpful to elect a leader, control the group size, share information or introduce rewards and punishments measures. This paper is based on Van Huyck’s weakest-link game, aimed at studying the influence of information feedback. Comparing data of different experiments, we analyzed the influence of information feedback. Results show that subjects performed better with more information in that they can reach higher equilibrium and cooperate successfully.
