Simulation Research on Diffusion of Agricultural Science and Technology for Peasant

In order to solve the problems like Chinese farmers' weak economic strength, low ability for receiving technology, and low efficiency of agricultural science and technology diffusion, the diffusion of agricultural science and technology among farmers is simulated and analyzed. By using the complex network theory and Net logo software, the spread of agricultural science and technology is simulated. Results show that the higher the "network-density" and "disseminator" are, the faster the agricultural science and technology diffuses, the more the "explorer" and "intensity" are, the faster the agricultural science and technology diffuses, however when the number of "explorer" and "intensity" reache a certain level, agricultural science and technology diffusion enters a platform stage, and the bigger the "cost" is, the smaller the "revenue" is, the larger the technical potential difference is, the more the time full coverage of agricultural science and technology consumes, The "environment" factor is not sensitive to the technology diffusion. Agricultural science and technology diffusion model and simulation established by using the theory and method of complex network, can provide a reference for the improvement of agricultural technology diffusion system and diffusion method.
