进口国知识产权保护与服务出口二元边际

摘要基于联合国服务贸易数据库,利用2000—2015年177个出口国和71个进口国的双边服务分行业出口数据,计算各国服务出口的二元边际,引入修正后的G-P指数衡量知识产权保护,使用泊松拟最大似然方法进行基准回归。结果表明:进口国知识产权保护程度的提升对伙伴国服务出口集约边际有显著的正向影响,对服务出口扩展边际产生负向影响。异质性研究表明,进口国知识产权保护对服务出口集约边际和扩展边际的影响及影响程度存在国别和行业差异。进一步研究发现,知识产权保护通过提高合同执行效率发挥市场扩张作用,推动服务出口集约边际增长;知识产权保护通过促进创新能力增强本土服务企业供给水平,完成国内市场的进口替代,负向影响服务出口的扩展边际。

关键词：服务贸易二元边际知识产权保护 G-P指数泊松拟最大似然估计

Abstract： Based on the United Nations service trade database, this paper calculates the binary margin of service exports of various countries by using the bilateral service sector export data of 177 exporting countries and 71 importing countries from 2000 to 2015. The revised G-P index was introduced as the key explanatory variable to express property protection, and the PPML method was used for baseline regression.The regression results show that the improvement of intellectual property protection in importing countries has a significant promoting effect on the intensive export margin of partner countries, and has a negative impact on the margin of export expansion. Heterogeneity research indicates that there are differences in the impact and degree of intellectual property protection in importing countries on the intensive and extended margins. Further study finds that intellectual property protection plays a role in market expansion and promotes intensive marginal growth by improving the efficiency of contract execution. It strengthens the supply level of local service enterprises by promoting the country’s innovation ability, completes the import substitution in the domestic market, and negatively affects the expansion margin of other countries’ exports.
