[目的/意义]未成年人互联网利用行为的形成过程相较于成年人而言更具复杂性和特殊性，探寻其形成原因有助于提升未成年人数字素养、引导其互联网利用行为良性发展并避免未成年人群体中新数字贫困的生成。[方法/过程]在扎根理论研究方法论指导下，对中国中部、东部、北部、南部、西部城乡共20个田野点展开以访谈为主的田野调查，借助三级编码分析方法，对未成年人互联网利用的行为、行为的影响因素构成和作用机制进行扎根理论分析。[结果/结论]人际网络、媒介空间和技术资本是未成年人互联网利用行为的外在客观动因，个体资本则是未成年人互联网利用行为的内在主观动因；初中阶段以前的未成年人互联网利用行为首先受到人际网络中父母、老师和家庭成员的影响，而初中阶段以后的未成年人互联网利用行为则首先受到个体资本和同学/朋友/他人的影响。未成年人互联网利用行为的小世界是由利用行为和影响因素共同构成并受年龄影响的动态空间。
[Purpose/significance] Compared with adults, the forming process of teenagers' Internet using behaviors is more complicated and unique. The study on influential factors will be useful for promoting teenagers' digital literacy, regulating teenagers' Internet using behaviors and avoiding creating new digital poverty in teenagers.[Method/process] Under the direction of grounded theory methodology, the paper made interviews in 20 locations of fieldsurveys including central areas, east areas, west areas, north areas and south areas of China. By using three-encoding method, the paper analyzes teenagers' Internet using behaviors, influential factors and their working mechanism on teenagers' Internet using behaviors.[Result/conclusion] The usefulness of technological capital, media space and social network is external and objective. However individual capital plays an internal and subjective role on teenagers' Internet using behaviors. Before 12-year-old, teenagers are affected by their parents, teachers and family members firstly. But they are much more influenced by their individual capital, classmates, friends and other people with aging. So the small world of teenagers' Internet using behaviors is a three-dimensional space which consists of age, influential factors and behaviors themselves.
