The essay deals with regional disparities in the average educational expenditure of every ordinary senior secondary student, including budget funds for education, the proportion appropriated to the ordinary senior high school by the government, tuition fee per student and the proportion of tuition fees of the total educational expenditure. By analyzing the relevant educational and economic indicators, we find that the average educational expenditure and tuition of every student in the western area are lower than those in the eastern and the middle area while the proportion of funds allocated by the government is the highest. However, in the middle area, both of the government appropriation of education funds for every student and its proportion of the total educational expenditure are the lowest in China, but on the other hand the proportion of tuition fee of the total educational expenditure and the income of the rural residents are the highest. Therefore, the aim of this essay is to look at the reasons why there are such differences.
