中日创新及国际贸易效应比较分析——以专利为例的实证研究

Comparative Analysis on Sino-Japan Innovation and International Trade Effect:Empirical Analysis Taking Patents as an Example

本文运用Johansen协整检验、Granger因果关系检验等计量方法,验证了一国的发明专利对该国贸易出口的直接促进作用;并通过中日两国的比较分析,发现日本的创新活动对该国的贸易出口促进作用比中国更显著。这说明在知识经济时代,一国持续的自主创新能力对该国的贸易竞争力乃至国家竞争力有着至关重要的作用。大量数据的比较显示,中国在自主知识创新方面同日本相比,差距是显然的。积极发展和完善我国创新系统,大力培育以知识优势为核心的国家竞争优势,是贯彻落实科学发展观,保持我国经济可持续发展的重要环节。

Through Johansen cointegration test, Granger causality test and other methods, this pa- per verifies that, a country＇s inventions can directly promote export trade, and its pulling effect is more visible than the total patents. Tests also manifest that the innovative activities in Japan play a more significant role in enhancing its export than in China. These show that in the era of knowledge economy, a country＇s sustainable ability of independent innovation is key to trade competitiveness and national competitiveness. Comparison of large amounts of data shows that the gap between China and Japan on independent knowledge innovation is obvious. China urgently needs to build a national innovation system, make great efforts to cultivate national competitive advantage centered on knowledge advantage, and improve our overall competitiveness.
