| Abstract: | In order to understand the competitive status in technology of steel enterprises in China, the patents of 73 key iron and steel companies in China are retrieved from Derwent Derwent Innovation Index(DII) and sixteen key steel enterprises of them are regarded as our research object.Each of the sixteen enterprises applied more than 300 patents from 1985 to 2013.Number of patent applications per year, patent citation, highly cited patents, IPC classification number is used to investigate the competitiveness in technology of sixteen steel companies.Results showed that Baosteel, Anshan Iron and Steel Group, and Wuhan Iron and Steel Group are strong in patent and technological competitiveness.With Derwent manual code for co-occurrence analysis, alloy steel and low carbon technology are identified as research and development focus in China's patented iron and steel technology from 2008 to 2013.The results can be used to clear their patented technology for enterprise competitive position and determine the direction of future technology development. |
