考虑区域因素、社会经济地位因素后,研究使用区县-学校-学生三水平模型,发现乡城移民学生占在校生的比例可显著负向预测其学校学业成就的均值,乡城移民学生比例越高,学校学业成就均值越低。而就读学校相同时,乡城移民学生和城市学生的学业水平没有显著差异。管理部门应继续改善乡城移民学生的入学环境,以减少对乡城移民学生的入学机会排斥。

Education authorities should further provide URIS more and better enrollment choices to reduce the access opportunities exclusion imposed on URIS.
