摘要：本文运用计量经济学的协整分析和Granger因果检验模型对中国和韩国的相关数据进行了实证分析，结果表明，专利数量与这两个国家产业发展存在长期稳定的均衡关系，即专利授权量的增加对两国的工业发展都有显著的价值增长效应。但中国的专利价值创造弹性较小，产生正向脉冲响应的时间也较慢，并对此做出尝试性解释。

Abstract: By using the methods of co-integration and Granger causal model of econometrics，the data for both China and Republic of Korea are comparably analyzed. The results show that there is a long-term equilibrium relationship between patents and industry development in the two countries，i.e. patents have a obvious value add effect on the industry development in the both countries. It is also found that the elasticity of value add of patents is little smaller in China comparing with that in Republic of Korea，and the impulse response time on the positive direction becomes slower as well.
