The salary level of teachers directly reflects the economic status of teachers in social wealth and has an important impact on the stable construction of the teaching staff. Improving teachers, salaries can appropriately address the shortage of teachers. At the end of the 20th century, most OECD member countries faced an emergency situation in which junior high school teachers were in short supply. The specific reasons were the decline in the professional appeal of junior high school teachers, the aging of junior high school teachers, the seriousness of junior high school teachers leaving in the middle, and the shortage of junior high school teachers in some areas and some subjects. The OECD member states have made many efforts to improve teacher's salaries and implemented a number of salary systems, including the differential salary system, the negotiated salary system, and the reward salary system, which have enabled teachers to boost their salaries, and the shortage of teachers has been moderately improved. These measures might have implications for China to establish a salary system for junior high school teachers with a gradual increase in total amount and a reasonable salary structure, and to improve salaries, and to alleviate the shortage of teachers.
