The nature of universities can be divided into two categories: one is public universities, and the other is that tuition is a necessary condition for private universities. Of course, you can apply for poverty allowance. With this condition, the universities that can enter are divided into many fractional universities, so the university market structure you mentioned can only meet the choices of consumers (students) who can pay tuition fees within the fractional range, so the products provided by fractional universities are its educational foundation. This is homogeneous, but the quantity is not large, so it is difficult to enter this market, so I think it is a monopoly, belonging to the trust country, and the Ministry of Education belongs to the organizer of the trust organization.
