摘要 本文利用时间序列数据,以大米为例,实证分析了2007~2008年粮食主产国出口限制对国际粮食价格的影响。研究表明:大米主产国贸易量对国际粮食价格有显著的负向影响;而且,2007~2008年期间大米主产国出口限制使大米贸易量每降低1%,则国际大米价格就上涨1.57%,而在此时间之外的大米贸易量影响并不显著。这说明,在特定时期粮食主产国的出口限制政策推动了国际粮食价格上涨。进而,本文利用脉冲响应函数分析了出口限制政策对国际粮食价格影响的动态变化。结果也显示,粮食出口限制推动了国际大米价格短期内大幅上涨,但其幅度低于化肥等生产资料价格上涨导致的国际大米价格上升。因此,本文认为:在区域合作框架范围内,通过区域内粮食主产国的磋商,限制粮食主产国出口限制政策的使用,将是抑制国际粮食价格大幅波动的可选政策。
