This paper analyzed the domestic and international corn prices in 1985-2014, to explore the connection of domestic and international maize price fluctuations. The results showed that the domestic and international maize prices had volatility, and continued to rise, there was irregular periodic fluctuation, and the domestic maize price was more fluctuant. By comparing the trend of domestic and international maize prices, we found that there was no obvious relationship between the domestic and international maize price fluctuations before 2005, but the association became gradually clear after 2005. |
