摘　　要： 本研究通过公共物品实验，发现与决策者无利益关系的负面和正面的信息冲击均导致显著的合作“重启效应”，没有信息内容的停顿没有统计上显著的“重启效应”。信息冲击只在短期内提升了合作水平，之后合作水平依旧延续了之前的下降趋势。该“重启效应”无法用“战略动机”或“学习”来解释。正面信息冲击对合作的短期影响要比负面冲击的大很多，这是因为正面信息冲击不仅提高了参与者自身的合作意愿，同时也提高了与他人合作水平的信念，而负面信息冲击和无信息内容的停顿不能提高参与者对他人合作水平的信念。 This paper shows that both negative and positive information shocks that are unrelated to decision makers can result in a significant restart effect compared to their counterparts in the control groups in linear public good games. No significant restart effect is found in the pause（ shock）-without-information treatment. Exposure to information shocks only has very short-term effect on cooperation, which continues to decline after a transient restart. Such a restart effect cannot be explained by strategic motives or learning. Positive shocks have much larger effects on cooperation than negative ones, because they not only in- crease subjects＇ willingness to cooperate, but also make subjects more optimistic about others＇ average contribution, while negative shocks or pause（shock） without information can＇t alter subjects＇ believes of other＇s average contribution.
