The identification of project level is very complicated, and it is difficult to simply divide it by administrative level. For example, there is a huge gap between provincial and ministerial projects and scientific research projects of the Ministry of Education. Even if it is a provincial project, there is a certain gap between provinces, so there is no uniform standard for determining the project level, which is generally determined according to the actual needs of users. The popular national, provincial and ministerial standards are also formulated by the society, not formal standards.
