Abstract Based on the data of 10 agricultural science and technology patent categories at the provincial level in China. By calculating the specialization index of regional agricultural science and technology and the situation of regional dominant agricultural science and technology to analyzing the development trend of agricultural science and technology at provincial level in China. Constructing the distance index of agricultural science and technology knowledge flow between regions to represent the situation of agricultural science and technology knowledge flow between provinces, and to clarify the difference of agricultural science and technology knowledge flow distance between provinces. Finally, The gravity model is used to measure the spatial interaction between regions caused by the flow of agricultural science and technology knowledge. The results show that: From 2000 to 2018, the agricultural science and technology in most provinces in China gradually showed diversified development, and the quantity of superior agricultural science and technology in each province also began to decline.The flow distance of agricultural science and technology knowledge among most provinces is generally small, and the structure of agricultural science and technology among provinces presents a certain homogenization, which is conducive to the agricultural science and technology exchanges and cooperation among provinces.The structure of agricultural science and technology in some provinces is quite different.
