摘　　要：利用主成分分析和协整分析对我国粮食生产的影响因素问题进行了研究。通过主成分分析,从粮食生产的影响因素中提出了基础因素和附加因素两个主成分,进而通过协整检验发现,粮食产量和两个因素间存在长期的均衡关系;最后通过回归分析研究了粮食生产影响因素的弹性问题。The impact factors of Chinese grain production were studied based on principal component analysis and co-integration analysis. Two principal components, the basis factor and an additional factor were extracted from the impact factors of grain production through principal component analysis and then the long-term balance relationship was found by co-integration test. Finally, some flexibility problems which can influence the grain production were studied by regression analysis.
