This study made an assessment of food security in APEC (Asia-Pacific Economic Cooperation) region with more attention to highlight grain production in food security system. To do so, the mechanism method was firstly used to calculate the productivity potential of radiation, thermal, climatic, and land productivity potential regressively, and to count the grain production potential in the whole APEC region. Based on the grain productivity potential, some important indicators were used to assess the food security of each APEC member economies under the framework of Analytic Hierarchy Process. The results show that the overall grain production potential of APEC region reaches as high as 1.7 billion tons. Compared with the real grain production of 1.1 billion tons, there is possibility for all the economies to increase their production in the future. However, when considering population carrying capacity and food consumption, food security status largely differs among individual economies, and expect for Japan and Korea, the developed economies is generally more secured than the developing economies. Exploiting land productivity potential at uttermost is a possible way to improve food security, yet at same time it is necessary to control population explosion, especially for those overloaded regions.
