On the basis of defining the connotation of grain and grain import safety,this paper analyzes the influen-cing factors of China's grain import safety from the aspects of grain quantity,grain quality,grain price,grain trade, national economy and ecological environment. Based on the super-efficiency DEA,this paper evaluates the safety sit-uation of China's grain imports from 1992 to 2015,and tests the significance of the indicators by constructing t statis-tics to overcome the defect of the super-efficiency DEA model which can not judge whether the indexes are signifi-cant. The results show that China's grain import security is in a safe state during the period from 1992 to 2015. Grain imports have little impact on grain price security and ecological security in China,and have a greater impact on quan-tity safety,quality and safety,trade security and economic security.%在对粮食及粮食进口安全内涵加以界定的基础上,从粮食数量、粮食质量、粮食价格、粮食贸易、国家经济、生态环境6个方面分析中国粮食进口安全的影响因素,基于超效率DEA模型构建中国粮食进口安全评价模型.对1992—2015年中国粮食进口安全状况进行评价,结果表明,1992—2015年中国粮食进口处于安全状态,粮食进口对我国粮食价格安全和生态安全的影响程度较小,对数量安全、质量安全、贸易安全和经济安全的影响程度较大.
