每一个身在科层体制当中的个体都被设计沿着科层向上层流动,然而众多研究发现科层对于普通人而言存在着“看不见的天花板”。本文试图通过深究L的读研动机来追溯L关于普通个体如何定义自我向社会上层流动的意义脉络。本文运用现象学社会学的理论来解读L个案的生平历程。通过深挖,发现个案L不但具有其个人独特的职业晋升困境,而且将其作为一种类型化的普通人群体来看待,实际上普通人群体面临着无能为力的晋升困境。 Every individual in the hierarchy has been designed to move up the hierarchy, but many studies have found that there are “invisible ceilings” for ordinary people in the hierarchy. This paper attempts to trace the meaning of L about how ordinary individuals define themselves to flow to the upper classes of society by studying L’s motivation for further studies. This paper uses the theory of phenomenological sociology to interpret the life cycle of L cases. Through deep digging, it was found that case L not only possessed its own unique career promotion predicament, but also regarded it as a type of ordinary people. In fact, the general population faced the helpless promotion difficulties.
