Since the founding of the People’s Republic of China，the process of administrative system change has been divided into three stages. From 1949 to 1978，an administrative system was gradually established，which is adapted to the nature of a socialist country and adapted to the planned economic system. From 1978 to 2012，an administrative system was gradually established，which is consistent with the socialist system with Chinese characteristics and adapted to the socialist market economic system. Since 2012，China has comprehensively deepened the administrative system reform in accordance with the requirements of improving and developing the socialist system with Chinese characteristics and promoting the modernization of the national governance system and governance capacity. With over 70 years of continuous change and reform，China has established a socialist administrative system with Chinese characteristics. The national administrative zoning system and administrative hierarchical structure in line with China’s national conditions have been gradually established. The responsibility system of government adapted to the socialist market economic system has been gradually improved. The government structure with Chinese characteristics has been continuously optimized. The level of administrative capacity and administrative efficiency to meet the requirements of governance modernization has been significantly improved. The change and reform of China’s administrative system over the past seven decades has provided valuable experiences and lessons.
