Since the government is the dominant force in the development and management of the economy, bureaus and departments have proliferated at all administrative levels. There are fifteen committees—such as the agricultural and state planning committees—one bureau, and twenty departments under the supervision of the Cabinet; of these, twelve committees—one bureau, and sixteen departments are involved in economic management. In the early 1990s, several vice premiers of the then State Administration Council supervised economic affairs. Organizations undergo frequent reorganization. Many of these agencies have their own separate branches at lower levels of government while others maintain control over subordinate sections in provincial and county administrative agencies.
