Abstract: In recent years, more and more engineering higher education courses are taught in bilingual languages But for students, as there are two education goals of bilingual course -mastering professional knowledge and learning languages, some courses’ results were not so satisfactory The main influencing factors on bilingual courses are discussed by establishing a structural equation model based on three aspects ie teachers, students and teaching environment of universities and an empirical study is carried out The results show that although double teaching goals of bilingual education require teachers’ and students’ English level, students’ learning attitudes and teachers’ influence on students’ enthusiasm are the most important factors on promoting the teaching quality

Key words: bilingual education, higher education, structural equation
