近年来,全球自然灾害频发,粮食供应紧张,生物燃料工业兴起,粮食需求呈刚性增长。在美国量化宽松货币政策的鼓励下,国际投机货币进入粮食交易市场,炒作农产品。以上种种效应叠加,造成国际粮价大幅上涨。 In recent years, with the frequent natural disasters in the world, the tight food supply and the rise of the biofuel industry, the demand for food has risen in a rigid manner. Encouraged by the quantitative easing monetary policy in the United States, the international speculative currencies enter the grain trading market and speculate on agricultural products. The above effects have been superimposed, causing a sharp rise in international food prices.
