Evaluating Cities’Independent Innovation Capabilities Based on Patent Using Data Analysis Methods

City innovation ability evaluation is becoming an important research field these days.The quantity and quality of patent that a city owns as well as the capability of managing patent institution indicate urban technological innovation ability and core competence.In this work,starting from patent analysis point of view,we construct urban technological innovation ability evaluation system.Factor analysis method is applied to 15 vice-provincial cities in China to analysis the collected patent data samples and a demonstration research is indicated upon the experimental results.Experimental results show that the littoral cities in south China have distinct advantages over the others in innovation activity,innovation capability,and innovation livability and innovation contribution.In the meantime,some old industrial bases own superiority in innovation cooperation and potential.
