摘要
随着全球经济一体化和我国改革开放的不断深入,我国与国际间的贸易往来日益密切,国内外市场价格联系更为紧密,特别是粮食价格关系到国家的粮食安全,越来越受到政府和学者们的重视。为了探讨国内外玉米价格波动的联系,通过比较分析1985—2014年国内外玉米价格数据,探究国内外玉米价格波动的特征,发现近30年来,国内外玉米价格始终持续波动,价格总体呈上涨趋势,且都存在不规则的周期性波动。其中,我国玉米价格在近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,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,
