Abstract: With the establishment and development of higher education disciplines in various countries, comparative higher education has become one of the important disciplines. Although attracted widespread attention in recent years, international comparative higher education research still faces many challenges, which also provides more possibilities for exploration. Related issues in the field of comparative higher education can be divided into method issues, cooperation and communication issues, and knowledge issues. Based on the above issues, research can be carried out to discover the differences and commonalities of higher education in different education systems, and to promote research in the field of comparative higher education.
