During the transitional period from 1949 to 10 to 1956, under the unified leadership of the central government, the administrative authorities for industry and commerce have done a lot of work to transform non-socialist economic sectors, develop the socialist economic base and develop the economy. However, when China's socialist transformation was basically completed in 1956, we implemented a highly centralized planned economic system. This economic system emphasizes that administrative orders and mandatory plans directly control social and economic activities and enterprise economic behavior. This economic system, to a certain extent, excludes the commodity economy and external supervision, so the functions of industrial and commercial administration are limited to managing rural fair trade and cracking down on speculation (to a certain extent, acts that conform to the laws of commodity economy, such as long-distance trafficking, are regarded as speculation). As a result, the functions of industrial and commercial administration are weakened, and many local industrial and commercial administrations are merged. Especially after the 1966 "Cultural Revolution" began, the industrial and commercial administration was severely damaged and the work was limited to paralysis. The State Administration for Industry and Commerce removed its brand in September, 1969, and was formally merged into the Ministry of Commerce in July, 1970, thus forming a situation that "the manager can't manage the workers, but the manager is managed by the merchants". At the level of provinces, municipalities directly under the central government and autonomous regions, only Beijing, Shanghai, Guangxi and Ningxia have retained industrial and commercial administrative organs, but there are few personnel. The administrative departments for industry and commerce of other provinces, municipalities and autonomous regions have been merged.
