The goal of the Chinese Government is to make China an efficient, modern economy by the end of the century. This goal was articulated by Premier Zhou Enlai in 1964 and 1975, and made public by Premier Hua Guofeng in February 1978, but a serious attempt at fundamental change was not begun until the strategic shift in economic policy following the Third Plenum of the 11th Party Central Committee in December 1978. Since then the Chinese have undertaken a bewildering variety of experiments and reforms in industrial enterprises. These experiments started on an extremely small scale, primarily in Sichuan, and then spread rapidly throughout the country. In 1982, however, after five years' effort, one enterprise in four was still operating at a loss.
