Evaluation Of Agricultural Technology Innovation Diffusion And Its Influencing Factors

With the rapid economic development of China and the expansion of urban-rural gap, rural economic development, more and more attention by scholars. Rural economic development is inseparable from the progress of agricultural technology, and advances in agricultural technology has mainly depend on the spread of agricultural technology and applications, agricultural science and technology can be transformed into productive forces and then promote the development of agriculture only being controlled and used by farmers.The paper take the Yangling as a diffusion source, tacking the apple-planting technology of Shannxi as a radiation area, the space-time laws about apple-planting is studied in this paper with s-shape curve model and gravity model. By use Logistic model, the impact of Shaanxi Province apple technology diffusion factors were analyzed, there are some important conclusions.(1) There are many models in Shaanxi Province about apple-planting technology diffusion in Shaanxi Province, but three models have the best effect, namely, farmers association mode, agricultural technology management mode and agricultural experts courtyard mode.(2) The dynamic mechanism are different of apple-planting technology diffusion in different spatial scales, at the macroscopic scale, the government forces and market forces have a greater impact; at the microscopic scale, the promotion way of technology intermediaries and Socio-economic environment of diffusion area have a greater impact.(3) It is found that the area of Shannxi apple-planting shows an upward trend in the fluctuations in time series, and there is a combined pattern of hierarchical diffusion and progressive diffusion on spatial sequence.(4) The different levels of regional economic development the spread of apple cultivation technology factors are not the same area, in a high level area, the external influence factors of apple-planting technology diffusion less affected, more information by farmers and the degree of their quality and other factors; low level of development in the region, farmers grow apples comparison to the strong dependence of external factors, by the national policy, transportation, irrigation and other factors more.
