摘　　要：在信息构成的世界里，每天都会有大量的网络信息被生产并得到快速的传播和利用。信息世界体现出来的生命延续和消亡现象，实际上是其价值老化作用的结果。然而，已有研究鲜有将“信息生命现象”与“信息价值老化”这二者之间关联梳理清晰的。因此，本文在理清当前学术界对信息老化问题的认识误区的基础上，结合信息的生命周期过程，从信息价值的产生、实现与损耗这三个方面，对信息老化的机理进行了深入讨论，提出了“信息价值变化”的概念模型，并得出了“熵增决定老化”、“价值损耗加快老化”、“知识存量决定寿限”等重要结论。In the world of information,a large amount of Web information is produced and then gains transferred and utilized speedily every day. Life and death （phenomenon） reflected in the information world, in fact, is the result of information obsolescence （value）; however, there were few researches that have made clear the relationship between ＂information life phenomenon＂ and ＂ information value obsolescence ＂. Therefore, on the basis of recognizing the misunderstanding on information obsolescence in current academic fields and combining with the viewpoint of information lifecycle,this paper investigates the mechanism of information obsolescence from three aspects - ＂production,realization and loss of information value＂. Finally ,the paper puts forward a conceptual model named as ＂information value change＂, and also makes some important conclusions ,such as ＂entropy determines information obsolescence＂ ,＂ information value loss increase obsolescence＂ and ＂knowledge stock determines the life span＂.
