本文基于2001—2010年我国蔬菜种子出口面板数据,在贸易引力模型的基础上,采用面板数据分析我国主要蔬菜种子出口国植物新品种保护实施及我国植物新品种保护效果对其进口我国种子数额的影响。实证结果表明,种子进口国加入UPOV公约的1978Act和1991Act对我国种子出口产生抑制作用,但显著水平较低;我国拥有的有效力的品种权数量对种子出口产生积极的促进作用。 Based on the trade gravity model, based on the trade gravity model, this paper analyzed the protection of new plant varieties in exporting countries of China's major vegetable seeds and the protection effects of new plant varieties in China on the amount of seeds imported from China influences. The empirical results show that 1978Act and 1991Act of seed importers joining the UPOV Convention have an inhibitory effect on the export of seeds in China, but their significance levels are relatively low. The number of effective varieties of seed owned by China has a positive effect on the export of seeds.
