资源困境中共同收益延迟的影响：时间折扣的调节效应

通过测量83名大学生的时间折扣率和不同共同收益延迟时距上的金币拿取量，以探讨资源困境中共同收益延迟对个体决策的影响及时间折扣的调节效应。结果表明：（1）金币拿取量随共同收益延迟时距的增长而增加，增加趋势和初始时间点的金币拿取量均存在显著的个体差异；（2）时间折扣率反向调节初始延迟时间点的金币拿取量，正向调节金币拿取量随延迟时距增长而增加的速率。这表明资源困境与跨期选择两个不同研究领域具有紧密联系，对当前资源保护制度的制定与实施具有一定的启发意义。

The Effect of Delay Joint Benefits in Resource Dilemmas: The Moderating Role of Temporal Discounting

To explore the relationship between the delay joint benefits and individual decision in resource dilemmas and the moderating effect of temporal discounting, 83 undergraduates accomplished the inter-temporal choice task and the hypothetical gold-coin-taking tasks in which there are different time intervals. The results showed that:1) the amount of gold coin which was taken increased with interval rising, and the increase rate over time and the amount of gold participants took at the first time interval were significant individual difference; 2) The moderating role of temporal discounting was negative for the amount of gold participants took at the first time interval and was positive for the increasing rate over time. These results indicated that resource dilemmas and inter-temporal choice are two strongly related areas, which is significant for the conservation of resources.
