Book excerpt: Examining the interaction between the Communist Party of China (CCP) and specific social categories (including peasants, workers, the middle classes, and the dominant class), with a focus on class and class discourse, this volume analyses the CCP’s impact on social change in China between 1921 and 1978. By exploring the CCP’s evolving discourse of class, this book demonstrates that, while class has retained its centrality, its meaning has been re-articulated from an ideological-political tool to a less meaningful signifier, though always used instrumentality. By examining the impact of the CCP’s policies and discourse surrounding class, it also reveals how its own policies since 1921 have shaped the CCP’s current (2021) perspectives on class and stratification. This volume, through an analysis of economic, political, and cultural inequalities in Chinese society even after 1949, also reveals the emergence of a diverse and often overlooked middle class in Chinese society during the 1950s. Delivering a detailed analysis of how the CCP has developed its practical approaches to class and mobilization, this study will be of interest to students and scholars of Chinese politics, Chinese history, Asian politics, and Asian studies.
