本文讨论了无限水平下代际福利路径集合上二元关系的存在性。我们表明，任何二元关系，满足匿名性和超规范连续性是不敏感的福利水平的变化，目前的几代人。这一结果推广了Diamond [Econometrica 33（1965）170-177]和Sakai [Social Choice and Welfare，16（2003）176-167]的不可能性定理。
This paper discusses the existence of binary relations on the set of intergenerational welfare paths in an infinite horizon setting. We show that any binary relation that satisfies anonymity and sup norm continuity is not sensitive to changes in welfare levels of the present generations. This result generalizes the impossibility theorems by Diamond [Econometrica 33 (1965) 170-177] and Sakai [Social Choice and Welfare, 16 (2003) 176-167].
