摘　　要：本文运用GL指数和GHM法定量测算并分析了我国农机产品产业内贸易的水平和类型特征,基于F-K理论模型对我国农机产品产业内贸易的影响因素进行了检验。结果表明:1)我国农机产品贸易的GL指数从1992年的0.28提高到2005年的0.70,说明产业内贸易水平明显提高,贸易主要形式逐渐从产业间贸易过渡到产业内贸易;2)我国农机产品贸易的水平型和高质量垂直型产业内贸易的GL指数接近于零,说明产业内贸易的类型属于低质量垂直型,呈现出口低质量产品、进口高质量产品的交换格局;3)经济发展水平和要素禀赋差异对我国农机产品产业内贸易影响显著,显著性水平在0.01以上。提高国民经济水平、缩小我国与贸易伙伴国的要素禀赋差异将会促进我国农机产品对外贸易的发展。Using the GL index and GHM method, the level and pattern of the Intra-lndustry Trade （IIT） of China agricultural machinery were measured and analyzed in this paper. Based on the F-K model, the factors that influenced the liT of agricultural machinery in China were tested. The results indicate that the GL index of China agricultural machinery trade increased from 0. 28 in 1992 to 0. 70 in 2005, which means the level of IIT has increased significantlyand the dominant trade form has transformed from inter-industry trade to intra-industry trade. Approximately, the GL index of horizontal IIT and high quality vertical IIT were zero, which indicated that the pattern of China agricultural machinery trade is low quality vertical IIT, and present a situation that low quality products were exported and high quality products were imported. The development level of economy and the differences of factor endowments have significant influence on the IIT of agricultural machinery in China.
