Abstract: The coexist of government administration centers in the Forbidden City and the Summer Palace not only wasted a large amount of resources，but also changed the old structure of centralized power in the Forbidden City and directly influenced the Qing’ s mode of operation. The rotation of administrative centers relied on institutional and economic capital but from the beginning of the Yongzheng reign，the locus of imperial power in the Summer Palace raised unprecedented questions of legitimacy among officials that persisted until the Xianfeng reign, a period replete with domestic trouble and foreign invasion. After the British and French forces invaded Beijing，and looted the Summer Palace in the tenth year of the Xianfeng，the Summer Palace was no longer used as an administrative center.
