Abstract:

Kazakhstan, which was the granary of the Soviet Union, is a large grain producing country. Research on grain production efficiency can evaluate its grain production potential and grain production level of future, and provide a reference for promoting Sino-Kazakh food cooperation. Based on the inter-state data of Kazakhstan from 2005 to 2017, this paper applied the Three-Stage DEA-Windows method to calculate the country's grain production efficiency in controlling environmental factors, and analyzed its dynamic evolution and regional differences. The results show that after excluding the environmental factors, the grain production efficiency fell sharply except for the northern region, and the average national efficiency dropped from 0.755 to 0.286. The differences in regional grain production efficiency are significant, with 0.857 in the northern part and only 0.112 in the western part, which means that there was much room for the increase of the grain production efficiency. After the adjustment, the grain production efficiency of the whole country and all regions showed an upward trend, but the efficiency gap between the North and other regions was continuing to increase. The changes of grain efficiency of different states in the same region tended to be similar.
