Abstract: Replacement  of  the  elderly  group  has  gradually  become  a  normal  phenomenon  of  population ageing  in  China． However ，current researches still focus on the size and structure of population of the elderly people． Thus ，it is of high importance to give an account of the replacement of the elderly group and to construct  a corollary  group analysis． This research proposes a theoretical framework for the group analysis including  concepts ，theories ，propositions ，indexes ，and applications．  The elderly group in this research refers to a cohort  group  having  same  experiences ，which  is  a  demography concept． Differences  within  the  elderly group ，which  can be explained by the life － course theory ，dynamism theory and chaos theory ，can be attributed to the effects of the environment and social construction． The differences can be measured by the indexes involving background ，capability ( behavior  and  consciousness) ，and  need． Paying  special  attention  to the group replacement ，caring about its initiatives ，dialectically analyzing its influence and adding a perspective of  group replacement to policies are among the important  areas of  applications of  the research

摘要： 老年群体更替已逐渐成为我国人口老龄化的一种常态化现象。但在已有研究中,重点依然是老年人数量和人口结构。因此,关注老年群体更替并建立一个相应的群体分析视角是必要的。文章提出了包括概念、理论、命题、指标和运用等部分的群体分析视角理论框架。框架中的老年群体是指出生同批和经历同期的人口学群体;老年群体差异是由环境、社会建构及其累积共同作用的结果,体现为生命历程理论、动态老龄化理论和混沌理论等;其差异性,既表现在背景、能动性和需求方面,又表现在影响和政策构建方面;并可通过背景、能力(行为和观念)、需求等指标进行衡量;重视群体更替、关注其能动性、辩证分析影响、增加政策的群体更替视角等均是运用中的重要问题。
