知识产权保护与国际R&D溢出实证研究

进口贸易和FDI是国际R&D溢出的主要渠道,知识产权保护水平是影响国际技术效应的重要因素。运用中国1985～2009的时间序列数据实证分析表明,进口贸易和FDI能显著促进国际R&D的技术溢出,且吸收能力的加强有助于技术效应的扩大。但是在现有中国经济的发展水平下,知识产权保护的加强会抑制国际技术溢出,阻碍中国劳动生产率的提高。因此,作为发展中国家,完善现有教育体制和提高人力资本自主创新才是关键,同时在不违反WTO协议的前提下,应采取适度的知识产权保护水平。

An Empirical Study on Intellectual Property Rights Protection and International R&D Spillovers

International trade and foreign direct investment are two important channels that affect international R&D technology spillovers.Intellectual property rights protection is one of the important factors which determine international technology spillovers.This paper uses China′s time series data from 1985～2009 and does empirical analysis.It finds that import and FDI have significantly promoted the international R&D technology spillovers.What′s more absorption capability will contribute to the expansion of technology spillovers.But under current level of China economic development,strengthening intellectual property rights protection will reduce the international technology spillovers and hinder China labor productivity increasing.Thus,China as a developing country should improve the existing education system and human capital to do self-innovation which is the key important thing.At the same time,under the promise of not againsting WTO agreements,China should adopt appropriate level of intellectual property rights protection.
