The most fundamental issue surrounding the 2nd Five-Year Plan was the prospect for increasing the rate of growth of Chinese agriculture. The Great Leap Forward was predicated on Mao Tse-tung's misunderstanding of the constraints facing Chinese agriculture. In large part the labor mobilization strategy was directed toward water conservancy and irrigation projects that were expected to raise crop yields substantially. The Chinese famine, by comparison, took from three to five times that number of lives and even surpassed the Soviet famine in proportional terms if Western estimates of excess mortality are used in place of the official figures. In higher-stage Agricultural Producers' Cooperatives (APCs), net income was distributed to APCs members according to their labor contributions. The recovery of production and other measures led to the reestablishment of price stability, particularly in rural markets. Industrial recovery was far more rapid than that of agriculture. The recovery of industrial and agricultural output is reflected in China's national income.
