It is no doubt that low fertility is now shaping China's population dynamics，and China's
population policy is at a crossroad. Singapore，Japan，Korea and Taiwan are quite similar to China in
terms of cultural traditions and policy trajectory，and all choose pro-natal policies，yet the results were
not satisfactory. The procedures of their policy transition can provide reference for China's policy op-
tions. This paper conducts an in-depth analysis of the motivation，process and features of policy change
in these countries /regions，explains the influencing factors，and compares the characteristics and out-
comes of population policy before and after the change. On such a basis，this paper recommends Chi-
na to adopt gradual policy transition and reform the supplementary policies in line with population con-
trol in order to maintain suitable fertility level.
