Do stronger intellectual property rights induce more agricultural trade?: a dynamic panel data model applied to seed trade
基于60个国家1990-2000年的面板数据，用动态面板模型分析知识产权保护强度对美国种子出口的影响，发现是否遵守知识产权协议对种子进口没有明显作用。
Abstract Do stronger intellectual property rights (IPRs) induce more agricultural trade? Based on panel data for 60 countries during 1990–2000 and using a dynamic panel data model, this article assesses whether and how national differences in IPRs affect the trade flow of planting seeds imports from the United States. The empirical results show that whether or not a country adheres to IPRs agreements has no discernible impact on planting seeds that are imported from the United States, implying that the strengthening of IPRs seems not to induce more agricultural trade. This result sheds some light on the debate in the theoretical literature on the importance of IPRs and trade.
