The proportion of degree supply refers to the proportion of the number of degrees provided by higher education institutions to the total population. This ratio reflects the coverage and quality of higher education in a country or region. A high degree supply ratio means that more people can receive higher education, thus improving their employment opportunities, creativity and social status.

The proportion of degree supply is closely related to economic development. With the economic development of a country or region, the demand for higher education is increasing, so the supply of higher degrees must be increased accordingly. However, the oversupply of advanced degrees will also lead to the decline of education quality and excessive competition in the job market. Therefore, the proportion of higher degree supply needs to be balanced and adjusted according to the actual situation.

Because the proportion of degree supply is of great significance to the future development of individuals and countries, many countries have set the goal of high degree supply. For example, in the "Thirteenth Five-Year Plan", China proposed that by 2020, the proportion of graduate students in the total number of graduate students in the country should reach about 45%, and the proportion of doctoral students should be raised to about 15%. The realization of these goals requires the supporting measures and policy support of the education system, as well as the individual's own efforts and the improvement of cognitive level.
