Abstract: The study of class (stratum) culture is an important field of cultural sociology. In order to fully understand the current research situation in this field at home and abroad, enrich and deepen the theoretical research of class and stratum, this paper sorts out the distribution of the main research literature on class culture at home and abroad, the origin, meaning, types of class (stratum) culture, and the ways to build a harmonious class culture by the classification method of "three research approaches and four levels of research content". Compared with the west, the domestic academic research on class culture is still in its infancy, which is in lack of theoretical analysis on the evolution logic and problem representation of class culture, systematic empirical research on the specific mechanism and realization path of class culture integration, comparative analysis between different classes, and even less of the lower culture and the new society stratum culture. From the perspective of research content, it is a trend to carry out comprehensive research and in-depth study on stratum culture.

Key words: stratum, culture, stratum culture
