基于专利计量的金砖五国国际技术合作特征研究

利用来自OECD的主要科技指标数据库中2001—2010年USPTO授权专利,数据从发明人国家和专利权人国家两个维度,采用专利国际合作发明和跨国拥有专利所有权两类指标,研究了金砖五国的国际技术合作特征。结果表明:金砖五国的国际技术合作活动非常活跃,中国和印度是全球国际合作发明专利数量增长最快的国家;金砖五国各国的国际技术合作程度存在较大差异;在跨国拥有专利所有权方面,金砖五国的专利权"输出"量明显大于"输入"量;专利产量、地域临近性以及政治、历史因素是影响金砖五国的国际技术合作倾向性的重要因素。

Study on Characteristics of International Technological Collaboration of BRICS Countries Based Patentometric Perspective

Using the data of patents granted by USPTO during 2001-2010 from Main Science and Technology Indicator Database of OECD, this paper adopts international co-inventor and the cross border ownership as the indicators to study the characteristics of international technological collaboration of BRICS from the two perspectives,namely the inventor and the applicant country. The results show as follows：BRICS countries participant in the international technological collaboration actively;China and India are the countries in which international co-inventions are in- creasing most rapidly~ the degrees of international collaboration vary in different BRICS countries;from the aspect of cross-border ownership, the ＂Exports＂ of BRICS is significantly more than the ＂Imports＂ of them; total number of patents,geographic distance and political and historical factors are the key determinants influencing BRICS countries＇ international technological collaboration.
