摘　　要：提出了农产品贸易边境效应引力模型,比较了中国区域间的农产品贸易和中国同美国各区域间的农产品国际贸易,考察了农产品贸易边境效应的变化趋势及其影响因素.基于1997-2005年农产品贸易截面数据的实证研究表明,中美农产品贸易存在非常显著的边境效应,且呈逐年下降趋势,农产品国际贸易流向和区域差异是影响中美两国间农产品边境效应的2个重要因素.With the fast development in China-U. S. agricultural trade, this paper made an empirical study on the border effect of China-U. S. agricultural trade. Applying panel data from 1997 to 2005, it compares the international trade and intra-national trade of China with U. S. to investigate the variation of border effect over time and across regions. The results indicate that border effect does exist in this regard and is significant with the tendency to dropping down by year; China-U. S. border has a large dampening effect on bilateral agricultural trade, is asymmetric and differs greatly across regions.
