摘要
选取240名大学二年级的学生,通过局域网信息反馈,进行了模拟投资的小组实验。结果发现,1、在连续性公共物品困境和自协调序列规则下,先前决策者的合作行为在决策的早期和中期起到了明显的榜样示范作用,并导致后续决策者的合作行为增加;2、这种示范作用在决策后期不起作用,被试出于搭便车或者担心自己利益受损的心理会表现出较高的竞争行为;3、先前决策者的竞争行为在整个决策过程中都起到明显的示范作用,使后续决策者的合作率保持在较低的水平;4、在没有任何信息反馈的情况下,被试倾向于在初期就做出投资决策,并表现出一定程度的合作行为。
The study investigated the effects of information structure on people's investment behaviors in a Continuous Public Goods Dilemma under a real-time self-paced sequential protocol (SPS) of games. The results showed that information about previous cooperative choices enhanced the followers' cooperation ratio at the beginning and in the middle of the decision process; but at the end of the process, the participants showed an obvious free riding or fearing of being sucked, then behaved very competitively; the information about previous competitive choices reduced the followers' cooperation ratio during the whole decision process; without any information provided, it seemed that the participants all rushed to the beginning of the process to make decisions and showed cooperation behavior to some extent.
