海外专利申请与中国企业出口产品多元化——来自“一带一路”沿线国家的证据

International Patenting and the Export Product Diversification——Evidence from the Countries along“the Belt and Road”

本文基于多产品出口企业贸易理论,构建了海外专利申请影响企业出口产品范围的理论模型,并利用中国2007—2013年在"一带一路"沿线国家专利申请数据,实证检验了中国企业海外专利申请对企业出口产品多元化的影响。研究结果表明:海外专利申请显著提升了企业出口产品多元化水平;专利质量的提升是出口产品多元化提升的主要原因;目的国模仿能力和知识产权制度的成熟度是海外专利发挥作用的关键因素。本文的研究不仅为企业进行海外专利申请提供了决策参考,同时对促进我国对外贸易高质量发展也具有重要意义。

Based on the trade theory of multiproduct firms,this paper constructed a theoretical model for the influence of international patent applications on firms’export product scope.It empirically tested the impact of Chinese international patent applications on firms’export product diversification by using China’s patent application data in the countries along"the Belt and Road"from 2007 to 2013.We find that international patent applications significantly improve the firms’export product diversification.The improvement of patent quality is the main reason for promoting export product scope.The imitation ability and the maturity of the intellectual property system of the hosting country are key factors that decide whether international patents can function properly.The research not only provides strategies reference for firms to apply for international patents,but also has great significance for promoting the high-quality development of trade.
