摘　　要：在利用灰色关联分析各农业生产要素影响基础上,建立山东省滨州市2002～2013年农业生产Cobb-Douglas模型,定量研究了农业机械化对农业产出的贡献率.结果表明,在此期间,农机总动力对农业总产值影响程度最大,对农业产出的贡献率达到了29％.Basing on the influence of agricultural production factors using Gray correlation analysis, the agricultural production Cobb-Douglas model was built from 2002 to 2013 for Binzhou City in Shandong Province. And the agricultural mechanization contribution rate was researched for agricultural output. The result showed that the gross agricultural machinery was maximum impact for agricultural output and the contribution rate was 29%.
