Party-based authoritarian regimes have often demonstrated remarkable resilience throughout wars, revolutions, and state-building processes. Yet how they consolidate authority in newly emerging socioeconomic fields that arise from the (partial) liberalization of socioeconomic policies remains insufficiently explored. This study examines the Chinese Communist Party’s (CCP) penetration into new socioeconomic organizations in the non-public sector, showing how it balances political control with socioeconomic vitality. We identify three strategies—coercion, indoctrination, and incentivization—framed within a process-oriented, three-step model that highlights ongoing CCP-organization dynamics rather than one-sided penetration. Drawing on resource dependence and organizational field theories, we explain both the Party’s strategic choices and organizational responses. This process has generated institutional isomorphism in the non-public sector, where party-building is increasingly viewed as a means of securing legitimacy and enhancing performance. Our analysis contributes not only to understanding CCP adaptability but also to broader debates on how authoritarian ruling parties consolidate authority in emerging fields.
