Abstract: Reviewing the changes in nuptiality and fertility behavior,family structure,and cause of death pattern of the Chinese population over recent decades,the author argues that it is far from complete and difficult to meet the practical demand of our era and population development to have an understanding demographic transition,especially the Chinese demographic transition from merely the conventional basic population dynamic involving birth,death and natural increase. Demographic transition is a multidimensional,dynamic and historical process,involving a combination of a serious of specific demographic transitions. Changes in birth rate,death rate and natural increase rate are only the surface or the "crust" of demographic transition.The "core" of demographic transition is the population behavior and its dynamic mechanism which are held by institutions,culture,and technology.Changes resulting from the "core" represent the intrinsic demographic transition.It is the important perspective and basis to understand the demographic transition with Chinese characteristics by looking at intrinsic demographic transition.Exploring the nature of demographic transition and reviewing the typical studies in demographic transition theory in China,the paper discusses future directions and research innovations in demographic transition theory.
