Abstract


Agriculture is the foundation of the national economy, and modern science and technology is applied to popularize the "weak". The new technology is rapidly and effectively spread to farmers, ability into productive forces. However in agricultural science and technology achievements exist in such a phenomenon: on the one hand, the amount of agricultural scientific and technological achievements, according to statistics, China is produced each year 6000 many of agricultural scientific and technological achievements, On the other hand, applied to practical production, generate economic benefits of scientific and technological achievements and rarely. Aiming at the farmer’s production is small in size and low level of socialization of socialization peasant conditions under the background, how to improve the rate of agricultural technology innovation diffusion, in order to accelerate agricultural science and technology achievements of research appears very important and necessary. Under the conditions of market economy, individual farmers as an independent operation, with the adoption of agricultural technology innovation process by individual factors except by farmers, the political, economic, social, environmental factors of influence, therefore, the system of agricultural technology diffusion process of the research of internal and external environment factors affecting farmers and agricultural technology innovation diffusion mechanism, to optimize environment and promoting the innovation diffusion agricultural technology innovation diffusion speed increase has important theoretical and practical significance.Taking Hebei agricultural technology innovation diffusion pear trees, for example, sociology, economics, agriculture, etc, to improve basic theory of agricultural technology innovation diffusion from the theoretical perspective, rate and empirical research method of Hebei province, through the spread of cultivation techniques of pear trees and verified rule curve with farmers themselves and external environment factors, further study of agricultural technology diffusion process technology choice behavior of peasant influence factors. Among them, using qualitative analysis method for experts, farmers are summarized and data statistics, the quantitative analysis method to adopt new technology diffusion curve and influence factors of empirical research and model estimation from farmers, personality and political, economic, cultural and other external environment factors and agricultural technology innovation diffusion process diffusion speed increase, the main factors affecting pertinently through improving the internal and external factors and finally farmers to increase agricultural technology diffusion speed provide theoretical and empirical evidence. The main research contents are as follows:1、In the selected on the basis of the study area, with different techniques for family produced during the study by the carrier, with innovation Cumulative value (or the cumulative percentage) in accordance with variable (Y), the time for innovation diffusion from variables (t), a method of nonlinear least flat Richards equation, agricultural technology innovation diffusion curve and the various parameters of the mathematical model, the maximum diffusion speed and promotion, age, theoretical and practical situation that the diffusion。2、The peasants’ individual characteristics belong to the internal and external environment factors, all belong to external causes through internal, according to the survey results, the farmer adopted new technology and households own internal and external factors make the correlation analysis based on the empirical research, using binary Logistic model of factors that affecting the screening, agricultural technology innovation diffusion rates of key factors.3、The key factor for screening, change farmers by behavior, improve the technology innovation of agricultural technology innovation diffusion efficiency of the basic strategies and methods are a direct change farmers themselves, 2 it is to change the production and living environment.
