过去50年来，全球农产品贸易的发展、“显示”比较优势和农产品净贸易专业化与贸易理论的预期大体一致，尽管贸易模式因反贸易政策而扭曲（缩小）。全球农产品出口的商品和国家份额都存在集中性：截至2014年，不到10种产品占农产品贸易的一半，世界农产品出口的三分之二由十几个农业贸易经济体（将欧盟28国视为一个经济体）占据。国际贸易中的粮食产量很少的一个后果是，只有少数几个国家主导着每种产品的国际贸易。
Developments in global agricultural trade, ‘revealed’ comparative advantage, and net trade specialization in farm products over the past five decades are broadly consistent with expectations from trade theory, even though trade patterns have been distorted (as well as being shrunk) by anti-trade policies. There is concentration in both the commodity and country shares of global exports of farm products: as of 2014, less than ten items made up half of that trade in agricultural products, and two-thirds of the world’s exports of farm products are accounted for by just a dozen agricultural trading economies (treating the EU28 as a single economy). One consequence of little food production being traded internationally is that just a few countries dominate each product’s international trade.
