Sovereign-owned enterprises (SOEs) are a class of enterprises that have been governed by the Party for more than 40 years. However, the political governance of SOEs remains largely unexplored. This study examines how the Party plays a leadership role in SOE governance through its ownership, cadre management, participation in decision-making, and intra-Party supervision. In this survey, we first review the evolution of China's SOE reforms during the past 40 years and the role of the Party during this period. Then, we present the overall structure of the SOE political governance, followed by detailed discussions of each pillar of the structure, with a focus on the most recent developments. The final part of this survey introduces both the status and the effect of incorporating Party-building work into corporate charters. Finally, conclusions are drawn and possible directions for future research are proposed.
