Standing Members of provincial-level committees of the Communist Party of China, commonly referred to as Shengwei Changwei (Chinese: 省委常委), make up the top ranks of the provincial-level organizations of the Communist Party of China. In theory, the Standing Members of a Party Committee manage the day-to-day party affairs of a provincial party organization, and are selected from the members of the provincial-level Party Committee at large. In practice, Shengwei Changwei is a position with significant political power, and their appointments are essentially directed by the central leadership through the Organization Department of the Communist Party of China.
