The key research base of humanities and social sciences of the Ministry of Education is built according to the standards of "first-class" and "unique". The so-called "first-class" means that the key research bases required to be established should be first-class in some research fields in the country, or at least in the same research field in universities across the country, and it is expected to reach the first-class in the same research field in the country after several years of construction. The so-called "unique" means that there is only one key research base in the same field and in the same research direction, and the required key research base has become the center of this research field and is obviously in the leading position in the prosperity and development of humanities and social sciences in China. After 10 years of construction and development, it can be said that more than two-thirds of the bases have achieved this construction goal, which can be called the academic peak, talent highland and exchange window in this field.
