本文通过四川省宣汉县对当地学校某些问题学生的实地调查，提出假设:问题学生与街角青年之间存在着密不可分的关系，前者成为后者重要的社会基础。问题学生的学校生活、家庭生活、街角生活等状况，已经显示出一些导致他们街角化倾向产生的因素。而社会经济发展模式、社会价值观以及大众传媒等的影响，更使得他们极易将街角青年的价值观内化，从而成为真正的街角青年。

The present study, based on the investigation into students from local schools in Xuanhan County in Sichuan province, poses the hypothesis that there is a close relation between problem students and street rascals, with the former group being the main social foundation of the later. Life of problem students in schools, families and around street corners has already indicated several factors responsible for their tendency of degenerating into street rascals, while the social pattern of cconomical development, social values and mass media's impact make problem students extremely liable to internalize values of street rascals and at last genuinely convert into them.
