The spatial pattern of global rice trade and its influencing factors
Rice,as one of the main grains,occupies an important position in global food securi-ty.Based on FAOSTAT global rice trade data,using spatial analysis methods and regression models,this paper aims to measure and analyze the spatial pattern of global rice trade and its in-fluencing factors from 2010 to 2021 The results show that:(1)The global rice trade has formed a spatial pattern with East Asia,South Asia,and Southeast Asia as the core layer,West Asia,East Africa,South Africa,and Oceania as the second layer,and Europe,North Africa,West Africa,South America,and North America as the third layer,presenting an obvious core-edge hierarchi-cal decline.(2)The spatial pattern of global rice trade is relatively stable,and the super position in the super core area is still strengthening.(3)The formation of the spatial pattern of the global rice trade is the result of the joint action of natural and human factors,of which population size and consumption habits are the dominant factors affecting the pattern of global rice trade.The research findings have important theoretical basis and practical reference for relevant countries or regions to formulate food import and export trade policies and maintain food security.
