韩、中、日三国的技术创新研究 ― 基于国际专利数据的比较 = The Study on Technological Innovation in Korea, China and Japan : Based on Comparison of International Patent Data

다국어 초록 (Multilingual Abstract)

本文主要依据世界知识产权组织提供的国际专利统计数据库(WIPO IP Statistic Data Center)，对韩、中、日三国2013-2017年期间在美国授权专利的状况进行分析。为了分析韩、中、日三国国际专利的动态变化，借鉴专利活动指数(PAI)对韩、中、日三国在美授权专利排名前5位技术领域进行技术集中度分析。主要研究结论有：第一，中国在国际专利申请及授权方面非常积极，国际专利申请和授权专利呈现出良好的发展势头。第二，中国和韩国授权国际专利的技术领域主要集中在几个领域，如计算机技术(Computer technology)，半导体(Semiconductors)，数字通信(Digital communication)，声响技术(Audio-visual technology)，电气机械设备及电能(Electrical machinery，apparatus，energy)等五大领域。第三，通过三国的PAI指数分析，在电信技术领域，韩国和中国的技术创新超越日本，而且中国在半导体领域的发展势头最强劲，但在电气机械设备及电能领域，日本的技术创新成果呈现突出的趋势。

Using the data of patents granted by USPTO during 2013~2017 from WIPO IP Statistic Data Center, this paper examines the general trend and the main technical fields of international patents granted to Korea, China and Japan. The Patent Activity Index(PAI) was used to analyze the dynamic changes of international patents in the top 5 technical fields.
The results show as follows. First, the number of international patent applications and registration by China has been increasing rapidly in recent years. Second, the technical fields of international patents granted by China and South Korea are mainly concentrated in several fields, such as computer technology, semiconductors, digital communication, audio-visual technology and electrical machinery, apparatus, energy. Third, through the PAI index analysis, the technology innovation and concentration of South Korea and China surpassed Japan in telecommunications technology field, and China’s development in the semiconductor field is the strongest. The technological innovation performance of Japan was analyzed as to be relatively higher than that of China and South Korea in the field of electrical machinery, apparatus, energy.
