Shanghai is administered as a direct-controlled municipality of the People's Republic of China, which means it has the same level of autonomy as a province. The city is divided into 16 county-level divisions: 15 districts and 1 county. Each of these divisions has its own local government led by a mayor. The Shanghai Municipal People's Government is the highest governmental authority in the city. It is headed by the Mayor of Shanghai. The government's responsibilities include urban planning, public transport, environment and sanitation, and maintaininAs a first-order, province-level administrative unit, Shanghai municipality is, in theory, directly controlled by the central government in Beijing. It is difficult, however, to gauge the precise nature of that relationship. Since the Cultural Revolution of the late 1960s, China’s administrative apparatus at all levels of the hierarchy has been in a process of readjustment so as to bring governmental organization in line with political reality. In 1967, early in the Cultural Revolution, the Shanghai Municipal Revolutionary Committee was established as the top governing body in the municipality after a chaotic period in which a number of popular-based revolutionary organizations seized control of the city for brief periods. The committee at that time was composed of representatives of the army, the mass revolutionary organizations, and some former Communist Party officials. By the mid-1970s that body had been replaced by a municipal government made up of commissions, offices, and bureaus responsible to the Shanghai People’s Congress, an elected body. Those units serve both policy advisory and administrative functions and function as administrative links to both the national government in Beijing as well as the local governing bodies.
