Statistical evaluation of agricultural protection by food exporting countries and impacts on world food markets

从影响国际市场的程度上分析了大型粮食出口国进行的包括生物燃料扩展在内的整个农业支持系统。泰国近期的政策发展趋势，虽然保护性越来越强，导致2009-2011年直接支付下的大米出口大幅增加，但此后转为市场干预，限制大米出口。即使考虑到新兴经济体的扩张，主要粮食的市场价格也高于根据世界生产和需求的基本趋势所估计的价格，而引发这一事实的主要因素之一将是美国的整个农业支持政策体系。

The whole systems of agricultural support including biofuels expansion conducted by large scale food exporting countries are analyzed in terms of the extent to affect international markets. The recent trend in the policy development in Thailand, though becoming more and more protective, contributed to a sharp increase in rice export under the direct payments in the 2009-2011, but it was changed to that of market intervention to restrict rice export thereafter. The market prices of major food grains are higher than that estimated to be generated from the fundamental trend in world production and demand, even considering the expansion in emerging economies, and one of major factors triggered this fact will be the whole systems of agricultural support policies by the United States.
