%X 粮食高库存威胁粮食市场稳定和国家粮食安全，优化粮食储备规模是当前粮食政策调整的关键。如何确定粮食最优储备规模？国内外学者对此展开了大量研究。国外研究从历史经验法起步，进一步提出能够反映储备多目标特征的目标规划法，以及能够根据市场情况调整最优储备规模的动态规划法，极大推动了粮食最优储备规模相关研究。中国学者普遍采用差额补偿法估算粮食最优储备规模，从单边补偿、双边调节和需求补偿三个角度丰富了差额补偿法。但总的来看，国内研究方法相对固化，对粮食储备及整个市场的刻画比较粗略，难以满足当前粮食市场发展和政策调整的需要。在当前中国粮食政策调整的紧要关头，有必要借鉴国外研究经验、基于中国现实情况，拓展和深化国内粮食最优储备规模研究。<br>Huge grain reserves threaten the grain market stability and national food security.Optimizing the size of grain reserves is the key issue in the current grain policy reform.Many foreign and domestic scholars have done a lot of researches on how to determine the optimal size of grain reserves.The foreign research started from the historical experience method,then evolved to multi-objective programming approach which could reflect the multi-objective feature of grain reserves and the dynamic programming method which allowed the dynamic optimal storage rules according to different market situations.These findings have dramatically pushed forward the related research.In China,scholars generally use the method of deficiency compensation to calculate the optimal grain reserve size and further enrich this method from three perspectives,namely unilateral compensation,bilateral regulation and demand compensation.However,the calculation methods in domestic research are relatively solidified.Besides,they fail to capture the details to meet the needs of strategic adjustment in current grain market.At the critical transforming point of China’s grain policy,it is necessary to draw lessons from foreign research,and expand and deepen the relevant research in the Chinese context.
