知识产权保护对中国对外直接投资影响的实证分析

Empirical Analysis of the Impact of Intellectual Property Protection on China's Foreign Direct Investment

本文以世界经济论坛发布的各国知识产权指数为核心解释变量,基于2011—2018年中国与一带一路沿线50个国家的面板数据,通过建立随机效应模型和GMM模型,发现一带一路沿线国家知识产权保护对中国OFDI具有显著的激励作用,并在国家发展程度、地理位置及知识产权保护水平强弱上体现出异质性。本文得出如下政策建议:一是政府应推动与一带一路沿线国家和地区双边投资协定的签订、修订和更新,强化沿线知识产权保护规则的完善;二是应建设国内知识产权保护体系,强化知识产权保护意识,缩小与发达国家的差距;三是跨国企业应提高知识产权保护意识,增强防范化解知识产权海外纠纷的能力。

Based on the panel data of China and 50 countries along the Belt and Road from 2011 to 2018,this paper takes the intellectual property index of countries released by the World Economic Forum as the core explanatory variable,and through the establishment of random effect model and GMM model,it finds that the intellectual property protection of countries along the Belt and Road has a significant incentive effect on China's OFDI,and reflects heterogeneity on the level of national development,geographical location and the level of intellectual property protection reflect heterogeneity.This paper draws the following policy recommendations:firstly,the government should promote the signing,revision and updating of bilateral investment agreements with countries and regions along the Belt and Road,and strengthen the improvement of intellectual property protection rules along the Belt and Road;secondly,we should establish a domestic intellectual property protection system,strengthen awareness of intellectual property protection,and narrow the gap with developed countries;thirdly,multinational enterprises should enhance their awareness of intellectual property protection and enhance their ability to prevent and resolve overseas disputes over intellectual property.
