摘要
基于2000—2009年我国种子出口面板数据,采用面板数据模型分析我国主要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。实证分析结果表明,种子进口国加入UPOV公约的1978Act和1991Act均对我国种子出口产生显著的抑制作用;但种子进口国拥有的有效力的品种权数量对我国种子出口的影响不显著;此外,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。
In this article,we present empirical results using a regression model to assess whether and how national differences in PVP affect Chinese seed exports.Panel data for 32 countries from 2000 to 2009 are used in the analysis to measure the impact of joining the International Union for the Protection of New Varieties of Plants（UPOV）.The results show that the differences in IPRs,measured by whether or not a country joins the UPOV,and strength of IPRs protection,measured by whether a member state performs under the 1991 Act or 1978 Act,have significant impact on Chinese planting seeds exports.However,importing countries′ titles in force at the end of reference year have no significant impact.Moreover,China′s titles in force are positively related to Chinese seeds exports.
