With the advancement of college education reform, the traditional College English listening and speaking class is facing many challenges, and most college students' English listening and speaking ability is gradually declining. Therefore, it is urgent to improve the effect of College English listening and speaking teaching, and relevant research has become the focus of education. Based on the theory of production oriented approach (POA), this paper makes a new design of classroom teaching of College English listening and speaking, and presents it in the form of flipped classroom. Then, a pre-test is conducted on the listening and speaking ability of economics students in a university, and then the comparative teaching is carried out. The experimental class (n = 29) was given flipped classroom teaching based on POA theory, while the control class (n = 29) was given traditional teaching. After a semester, the two classes' English listening and speaking ability was tested again, and the results before and after the two classes were compared. Finally, a questionnaire survey was conducted among the students in the experimental class and an interview with the English teachers. The experimental data show that the listening and speaking scores of the experimental class are improved by 13.75% and 17.02% respectively before and after the experiment. The results of listening and speaking in the control class were improved by 4.78% and 7.16% respectively. The minimum value of adaptability factor is selective learning, which is 1.55, and the maximum value is learning attitude, which is 4.95. 76% of the total number of students like and prefer this teaching mode. 48% and 31% of the students think that the teaching mode in this paper is very beneficial to the development of their own learning habits. Under this teaching mode, the average time of lesson preparation in each unit is about 52.6 minutes, and the difficulty of lesson preparation and teaching is also within the acceptable range. 50% and 33% of the teachers think that this teaching mode is very beneficial to improve their professional skills. This shows that flipped classroom teaching based on POA theory can improve students' English listening and speaking ability and teachers' professional skills, and its adaptability is good, which is worth promoting.
