The Measure Of Information Content In Agricultural Technology Diffusion

The agrotechnical diffusion, which begins with technological innovation, is the course that generalizes to the agricultural consumers by the technical extended organization. This article takes the basic of agrotechnical diffusion as the main line, regards the whole system of agrotechnical diffusion as a dynamic consecutive course, and divided the course into three sub-systems, viz. science and technological innovation, technical diffusion and technical application. The contact of the three depends on the flow of information in different course in the whole system.On the foundation of standardizing the conception of agrotechnical diffusion, this article indicates that the agricultural diffusion is an important method to quicken the transform of agricultural technology, a way for the science and technology to make the agriculture product be modern scientific, a mean to make progress of agriculture, rural area, and increasing the farmers'income. It analyses the information flowing in dynamic and static state among the essential body of the diffusion—science and educational departments, intermediary extended organizations and the objective receivers, indicates the trait of the diffusion system, the information flowing course. It further discusses the operation mechanism of the system of agrotechnical diffusion and indicates that the essence of technical diffusion is information diffusion, and the system depends on the course which information flows from the fountainhead to the receivers. And it analyzed the ingredients which influence the information flowing in the system. Intruding Shannon's information...
