英文摘要：

The complexity of patent determines that the related researches of patent should be from many aspects. In this paper, after the introduction of the connection and difference between dynamic network analysis （ DNA） and social network analysis （ SNA） , the patent network with multi attributes is constructed on the basis of Beijing nano patents, then the DNA approach is used to analyze the patent net-work＇s evolution and dynamic features, the potential important relations and changes are identified, and finally the analysis result is conclu-ded.
