近30年内，波动幅度更为剧烈，价格涨幅更大。通过比较国内外玉米价格波动的走势，发现2005 年以前国内外玉米价格波动关系不大，发现2005 年以后国内外玉米价格关联性逐渐明显。 |

| With the deepening of global economic integration and Chinese economic reform, China becomes increasingly integrated with the world. And market prices become more closely, particularly grain price related to national food security, that the government and scholars pay attention to. 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. |
