Abstract:

According to the data of maize planting cost of China and America from 1998 to 2016, an analysis was made to compare the quantity and the structure of maize planting cost between China and America. The results showed that: the planting cost of maize in China grew faster than that in America, and planting maize in China had been changed from advantage with lower cost to inferiority with higher cost; the cost structure in China was dominated by indirect costs, and that in America was relatively balanced; the changing rules of different cost items had different points in different periods between China and America. At the same time, it was pointed out that the difference in production scale, production mode, the content of science and technology and the guarantee means were the main reasons of causing the difference in the cost of maize planting between China and the United States. Finally, based on the experience of cost control for maize planting in the United States, the optimization path of China's maize planting cost in the future was put forward.
