The main factors affecting food production were empirically tested. The GAEZ method is used to measure the food production potential and development potential of the five Central Asian countries; the third is to analyze the grain trade in Central Asia, and discuss the characteristics of grain import and export trade in Central Asia from the perspective of trend, structure and market distribution. The threshold panel model and the trade gravity model are used to conduct empirical research on the influencing factors of grain import and export trade in Central Asia, and then use the international market share index and the trade competition index to measure Kazakhstan’s international grain competitiveness and grain export trade potential; fourth, countermeasures and suggestions are put forward for grain production and trade in Central Asia.
