As political stability was gradually restored, a renewed drive for coordinated, balanced development was set in motion under the leadership of Premier Zhou Enlai. To revive efficiency in industry, Chinese Communist Party committees were returned to positions of leadership over the revolutionary committees, and a campaign was carried out to return skilled and highly educated personnel to the jobs from which they had been displaced during the Cultural Revolution. Universities began to reopen, and foreign contacts were expanded. Once again the economy suffered from imbalances in the capacities of different industrial sectors and an urgent need for increased supplies of modern inputs for agriculture. In response to these problems, there was a significant increase in investment, including the signing of contracts with foreign firms for the construction of major facilities for chemical fertilizer production, steel finishing, and oil extraction and refining. The most notable of these contracts was for thirteen of the world's largest and most modern chemical fertilizer plants (see Chemicals , ch. 7). During this period, industrial output grew at an average rate of 8 percent a year.
Agricultural production declined somewhat in 1972 because of poor weather but increased at an average annual rate of 3.8 percent for the period as a whole. The party and state leadership undertook a general reevaluation of development needs, and Zhou Enlai presented the conclusions in a report to the Fourth National People's Congress in January 1975. In it he called for the Four Modernizations (see Glossary). Zhou emphasized the mechanization of agriculture and a comprehensive two-stage program for the modernization of the entire economy by the end of the century.
