自十八世纪末开始，“成长”主题经久不衰。总的说来，在一水之隔的台湾，二十世纪七十年代以来的成长小说是立体化和多样化的，没有被限定在某一种类型之中。作家具有自觉的成长意识，创作也比较自由。通过窥探青少年的行为和心理，能够看到时代和社会的光影。“家庭”可能就是青少年主体性生成需要突破的第一个牢笼，离开家，是个人成长中必不可少的一环。离家出走，可能是走向了曙光，但也有可能迷失、甚至死亡。二十世纪七十年代以来台湾成长小说中，青少年“离家”主要有三种叙事模式：①苦痛—接受—融入；②苦痛—反抗—死亡；③苦痛—放纵—流浪。三种叙事模式下的成长小说有各自独特的书写背景、情节模式以及审美意义。

The theme of growth is enduring in literary creation since the end of the eighteenth century. Generally speaking, the initiation story is tridimensional and multiple since 1970s'in Taiwan, just across the border from China. It is not limited in a certain type. The writer has the consciousness of the growth and the creation is free. From the youth's psychology and behaviors, we can see the changes and faces of the time and society. In the process of teenager growing up, their subjectivity have generated. In the same time, the family may be the first cage to be break. Leaving home is a necessary link in the growth of a person. After the youth runs away from home, he may owe a bright future, but may also be lost even die. There are three different narrative patterns about the youth leaving-home in the initiation story since 1970s'in Taiwan: ①suffer-accept-integrate;②suffer-revolt-die;③suffer-indulge-wander.
