The high-quality development of education is the development to meet the high-quality demand, the development under the guidance of the new development concept, the development to completely change the educational development mode, optimize the educational structure and change the growth momentum, and the development from "quantity catching up" to "quality catching up", from "scale expansion" to "structure optimization" and from "factor driving" to "innovation driving".

The high-quality development of education is not only an innovative conceptual representation of the spirit of the era of high-quality development of the education system, but also a realistic response of the education system to the public's demand for high-quality education and more education. ?

This policy discourse is not a fixed single expression, but a discourse pedigree of high-quality development of education formed in various policy texts and contexts, such as "high-quality development of education", "high-quality education system", "high-quality education demand" and "standard system of education quality", which objectively constitutes a series of policy concept pedigrees related to high-quality development of education. ?

The so-called policy concept pedigree refers to a series of policy discourses with high-quality educational development, which formally express differences in different times, occasions and contexts, but focus on a certain educational purpose or spirit, forming a continuous but different, close and inclusive, unique and related innovative policy discourse practice. ?

From the perspective of genetics, we can examine how the term "high-quality development of education" appeared and evolved in the national policy texts.
