ABSTRACT: Based on the analysis of
China’s grain production and demand quality grade, this paper uses the
non-equidistance GM (1,1) model and the inference algorithm to predict the
structural balance of the supply and demand grades of China’s four major grain crops. The results show that the
supply and demand for wheat, corn and rice can maintain a quantitative balance.
While, it’s difficult to achieve a quality grade balance in wheat and rice and
keep a supply and demand balance in terms of quantity and quality of soybean.
Simultaneously, the
supply of premium grade corn is greater than the demand. The analysis and
prediction results can reflect the existing structural balance matter of grain
supply and demand at different quality grades in China, and provide theoretical basis for
governments to formulate relevant policies.
