Abstract

Abstract: Abstract: Combining with the classic statistic method, co-citation method, and the newest visualization tools, the patent analysis between China and abroad in the view of academic distribution, co-citation network, and research frontier is revealed and compared. According to this it is found that using quantitative analysis of patent to explore its economic and strategicvalueis thebiggest hot point in recent years and the direction of patent analysis for Chinese scholars is pointed out.

Key words: patent analysis, comparison study, visualization, frontier hot point
