The policy of "adjusting, consolidating, enriching and improving" the national economy was put forward for the first time in the report. Prior to this, when Li Fuchun studied the national economic planning control number 196 1 in the middle and late August, he proposed that economic work should be arranged according to the principle of "adjustment, consolidation and improvement" according to the spirit of the Shanghai Conference and the Beidaihe Conference, especially according to Zhou Enlai's opinion.
