摘要翻译：
在以往的空间公共物品博弈研究中，每个参与者都能够建立一个群体。但在现实生活中，一些玩家因为各种原因无法成功组团。本文提出了一种声誉驱动的群体形成机制，只有声誉达到或超过某个阈值的玩家才能组织群体。我们将一个玩家的声誉定义为在最后$T$时间步骤中合作的频率。我们发现，当群只由总是在最后$T$时间步骤中合作的纯合作者建立时，可以获得最高的合作水平。本文还研究了记忆长度$T$对合作的影响。

英文摘要：
  In previous studies of spatial public goods game, each player is able to establish a group. However, in real life, some players cannot successfully organize groups for various reasons. In this paper, we propose a mechanism of reputation-driven group formation, in which groups can only be organized by players whose reputation reaches or exceeds a threshold. We define a player's reputation as the frequency of cooperation in the last $T$ time steps. We find that the highest cooperation level can be obtained when groups are only established by pure cooperators who always cooperate in the last $T$ time steps. Effects of the memory length $T$ on cooperation are also studied.
