Studying the validity of Ideological and political education of non-party intellectuals in colleges and universities from the perspective of reception theory is not only the change of research perspectives, but also the change of the roles of educational subjects and recipients. To improve the validity of Ideological and political education of non-party intellectuals in colleges and universities, we must pay attention to their "horizon of expectation", stimulate their subjectivity and activity to participate in education, meet their development needs, strengthen the pertinence of Ideological and political education, and urge them to accelerate the transformation process from internalization to externalization actively, rather than passively.
