中文摘要：

加强知识产权保护能够激励R＆D投入,而R＆D投入能够增加技术知识存量。引入技术知识存量作为技术创新的代理变量,利用15个OECD成员国1980～2003年间的面板数据,采用固定效应回归模型,检验了开放经济体国家知识产权保护的经济效果。研究结果表明,在开放经济体国家,加强知识产权保护能够促进经济增长,且技术知识存量越大,加大知识产权保护力度对经济增长的促进作用越显著。

英文摘要：

Stronger intellectual property rights（IPRs） can stimulate RD investment,which will increase technology knowledge stocks（TKS）.By including TKS as independent variable,this paper examines the effect of IPRs on economic growth in open economies.Using a panel of 15 countries from 1980 to 2003,fixed effect estimator is applied to conduct empirical analysis.The results suggest that the effect of IPRs on economic growth is positive and significant in open economies,and the effect of IPRs on economic growth is larger the larger are the TKS.
