摘　　要：在集体物品逐渐损耗过程中,个体是否能够采取捐赠的合作供给行动以维护更新该集体物品,属于多人困境问题的一种具体情况。通过在个体跨期均衡模型中引入集体物品初始存量和衰减速率,考察集体成员间主观贴现率差异与捐赠的合作供给关系。分析发现,集体物品被个人捐赠供给的主要因素之一是成员对集体物品的主观贴现率有较大差异;且初始存量和衰减速率不同的情况下,主观贴现率差异对集体物品捐赠供给的影响是有区别的。In the gradual loss process of collective goods, the individual is able to take donatives cooperative action to maintenance or update the collective goods belonging to a specific circumstance of N-person＇ dilemma. By introducing collective goods initial stock and decline rate in the inter-period equilibrium model, this paper investigates the relationship between the collective members＇ subjective discount rate differences and donatives cooperative supply. The analysis finds that one of the main factors the collective goods donated by the individuals lie in the fact that collective members＇ subjective discount rates are different; and with the different initial stock and the decline rate, there are distinctions between the impacts of the subjective discount rate differences to the collective goods donatives supply.
