1, enrollment expansion, also known as college enrollment expansion, university enrollment expansion or college enrollment expansion, including graduate enrollment expansion, undergraduate enrollment expansion and higher vocational enrollment expansion, refers to the educational reform policy of college enrollment expansion in China and Chinese mainland since 1999, which is based on solving economic and employment problems, that is, higher education since 1999.

2. The enrollment expansion originated from 1999 "Action Plan for Revitalizing Education Facing 2 1 Century" issued by the Ministry of Education. The document proposes that by 20 10, the gross enrollment rate of higher education will reach 15% of the school-age youth. After entering 2008, the Ministry of Education said that the enrollment expansion from 65438 to 0999 was too hasty, and the proportion of enrollment expansion was gradually controlled. However, in the context of the global financial turmoil in 2009, the Ministry of Education began to adjust the enrollment ratio of graduate students.
