Abstract:Through the invention patent information disclosed in the China patent database, and using the patent maps and patent-bibliometric analysis methods, the paper systematically analyzes and compares the competition trend of stem cell industry in our country, from the aspects of overall development trend, regional distribution trend, innovation subject competition advantage, R D team efficiency, R D hot points and technology relevance etc.. The research shows that, the quantity growth of stem cell industry patent technology in our country is strong, and our main competitors are from America, Japan and South Korea of these developed countries, and the research advantage of research institution and university is stronger than the enterprises in China, and our leader talent of R D team is far fewer than the foreign, and China"s patent quality is lower than the foreign. This research is to provide decision reference for patent strategy and related industrial policy construction of stem cell industry in our country.
