Abstract: In order to understand the status, strength and development trend of agricultural technology, quantity, IPC category and the stage of technological development of patents were analyzed using patent analysis method based on the data of Beijing Academy of Agriculture and Forestry Sciences, Tianjin Academy of Agricultural Sciences and Hebei Academy of Agriculture and Forestry Sciences from 2012 to 2014. The results showed that Beijing Academy of Agriculture and Forestry Sciences had obvious advantages in terms of patent quantity and research field coverage, Tianjin Academy of Agricultural Sciences and Hebei Academy of Agriculture and Forestry Sciences had relative advantages in the research field of patent. With the coordinated development of Beijing- Tianjin- Hebei region, the authors suggested that the three agricultural scientific research institutions should combine generic technology and make their respective advantages complementary to each other in agricultural science and technology innovation.
