There were minor efforts toward relaxing central control of the economy in the 1980s that involve industrial enterprises. Encouraged by Kim Jong-il's call to strengthen the implementation of the independent accounting system (, "tongnip ch'aesanje") of enterprises in March 1984, interest in enterprise management and the independent accounting system increased, as evidenced by increasing coverage of the topic in North Korean journals. Under the system, factory managers still are assigned output targets but are given more discretion in decisions about labour, equipment, materials, and funds.
