“High-precision” industry is an important carrier to get rid of rough production mode in China，and it is also of great significance to realize the transformation of economic development mode in Beijing. On the premise of clearly defining the connotation of “high-precision” industry in Beijing，this paper will take the innovation and development level of “high-precision” industry as the starting point，design the corresponding index index，and add the corresponding index score of the whole country to compare. In order to comprehensively and objectively reflect the current Beijing related industry development innovation level. Empirical results show that the innovation ability and development potential of Beijing’s “high precision” industry continue to be higher than the national level in 2014～2018，the main reason is that Beijing’s investment in science has been maintained at the national level. However，Beijing’s scores on indicators such as “University Science and Technology Park” also lag behind the national level. In view of these problems，from the point of view of “further improving Beijing’s” excellent “industrial innovation ability ”，we put forward corresponding policy suggestions.
