Abstract:

【Purpose/significance】The effective transmission and adoption of S&T information is the driving force for advancing infor⁃

matization construction and promoting economic development. In the face of information transmission dilemmas such as the "informa⁃

tion gap" and the "last mile of information services", it is of great significance to accurately understand the diffusion-absorption operat⁃

ing mechanism, influencing factors and efficiency of scientific and technological information, and to design diffusion-absorption en⁃

hancement strategies in a targeted manner.【Method/process】The operational incentives and influencing factors of the diffusion and

absorption of S&T information were analyzed in this paper. By using system analysis, the information diffusion and information absorp⁃

tion are regarded as two related subsystems. The network DEA model is used to measure the diffusion and absorption of agricultural

scientific and technological information in China. Through efficiency analysis, we have obtained the direction of improving the efficien⁃

cy of the main body of supply and the absorption of farmers, and designed the direction of efficiency that promotes the diffusion and ab⁃

sorption of agricultural science and technology information.【Result/conclusion】Combining the research conclusions, the correspond⁃

ing measures to promote the diffusion and absorption of agricultural S&T information were proposed.【Innovation/limitation】An intu⁃

itionistic chain structure of agricultural science and technology information diffusion and absorption was established,the selection of in⁃

put index, intermediate index and output index of agricultural science and technology needs to be further expanded.
