This paper constructs a technology competition index system based on DMC patent data, and analyzes the technology competition situation from the scale of competition, the extent of enterprises association and the competition among enterprises through the social network analysis. It also verifies the method by extracting the DMC of electric vehicle battery patents from 1979 to 2013 with the data mining technology and analyzing its technology competition dynamic evolution process, to provide reference for technology competition situation analysis of different industries from the patent perspective.
