Taking 378 migrant children’s families in Xi’an as samples, the present situation of language education in migrant children’s families in Northwest China was investigated by means of questionnaires. This paper uses Probit model to analyze the influence of family language attitude and environment on family language education of migrant children. The research conclusions are as follows: (1) Parents of migrant children have the willingness to carry out family language education, but due to income, environment, cultural level and other reasons, the quality of family language education for migrant children in Northwest China is low. (2) Parents’ attitude toward family language and family language supervision is the key factor influencing migrant children’s acceptance of family language education. When the family language education level is not high, it will also effectively promote the family language education of migrant children.
