The key to realize educational equity is to solve the problems of educational equity and justice. Educational equity refers to the reasonable norms or principles for the state to allocate educational resources. "Reasonable" here refers to the unified allocation of educational resources from the dialectical relationship between the overall development and stability of society and the individual development needs of social members.

The concept of educational equity has a long history, and the pursuit of educational equity is an ancient concept in human society. Historically, Plato, a great thinker in ancient Greece, first put forward the idea of educational equity, and Aristotle first put forward the idea of protecting the educational rights of free citizens through law. Two thousand years ago, Confucius, a great educator in ancient China, also put forward a simple idea of democratic education. The modern western bourgeoisie is committed to seeking educational equity. By the end of 18, the idea of educational equity has been transformed into legislative measures in some western countries, which legally guarantee everyone to have equal educational opportunities.
