The Effect Of Social Network On Adoption Of New Technology By Farmers

strengthening the promotion of modern agricultural science and technology innovation system.To provide accurate support for the basic level agricultural technology extension of public welfare and operational service institutions,and guide agricultural services in Colleges and universities.Implementation of science and Technology Commissioner System to encourage the support of science and Technology Commissioner in the first line of innovation and entrepreneurship.Play the role of rural professional and technical associations.Encourage the development of agricultural high-tech enterprises.In recent years on the importance of strengthening the research and innovation of agricultural production,stressed the need to make real use of cutting-edge technology,but for farmers,in fact China's agricultural technology transformation rate has been at a relatively low level,in this context,this paper attempts to solve three problems:(1)if the technology is conducive to the increase of economic benefit,why farmers do not use?The lack of information knowledge is the main factor that restricts farmers to adopt new technology?(2)social network as a carrier of resources has a significant impact on farmers to master the technical level?Whether the threshold effect of social network(3)if the communication network is conducive to the technical information and technical support,whether farming agglomeration subject is embedded in new technology adoption showed the spatial correlation of the reason?In this paper,farmer behavior theory and through a literature review of the research status in this field,and then to freshwater aquaculture water microbial technology as the research object,through the empirical test of each problem in Jiangsu,Zhejiang and Guangxi provinces,four cities,ten counties and 59 valid samples and 343 valid village peasant sample.The main research results and conclusions are as follows:(1)the use of microbial water transfer technology can effectively improve the farmers' economic benefits,descriptive analysis,variance analysis,PSM test and regression analysis results support this conclusion;(2)OLS model and ordinal logit model showed that the technical mastery of information and knowledge in 1%the level of significant positive impact on Farmers'technology investment intensity and the degree of investment,intangible information is an important production factor,grasp the information technology significantly promote farmers' adoption of new technology adoption and adoption of strength;farmers health,risk attitude,family income,non-agricultural income proportion has significant positive impact on the adoption of the new technology,changing the water the frequency of negative effect of adopting new technology;education and culture area significantly negative effect on new technology investment intensity;industrial group Weaving and technical training did not have a significant impact on Farmers' adoption of new technology;(3)the results of OLS model show that social network has a significant role in promoting farmers' learning and mastering new technology.Among them,the horizontal and vertical network network scale for the farmers to master technical level has a significant positive effect on the level of 1%,oblique network scale for the farmers to master technical level has a significant positive effect on the level of 10%;horizontal network strength,network strength,longitudinal oblique network strength of the farmers to master technical level has a significant positive effect on 1%the level of;(4)the horizontal and vertical network of farmers to master network technology level has a threshold effect,when the network size is below the threshold value,the network is not significant positive impact on farmers to master the technical level,and when the network scale is higher than the threshold value,the network has significant positive impact on farmers to master the technical level;oblique network there is a threshold effect for farmers to master technology level,but different from the horizontal and vertical network,while diagonal network size is below the threshold value,the farmers to master technical level has a significant positive effect when the network scale is higher than the threshold,the master has no significant effect on Farmers' technical level;(5)strong networks have a direct impact positively on new technology,information dissemination,weak ties have no direct effect on the new technology of information dissemination,but by the strong pass As the bridge relations indirectly promote farmers to access information;in the horizontal and vertical network,the direct effect of strong ties than weak ties,in the oblique network,the direct effect of indirect effects of weak ties than strong ties;insummaryofthesetwopoints,Granovetter "weak ties hypothesis cannot fully explain the new communication mechanism agricultural information technology;other significant influence the farmers to get new information technology factors including health status,risk attitude,family income,family income and non-agricultural income accounted for the proportion of water exchange frequency,industrial organization and technical training for farmers to acquire new information technology did not have a significant impact;(6)through theoretical analysis that agricultural species(raise the effect of grafting and agglomeration)learning embedded in the main technical support can stimulate social network,promote the dissemination of information and knowledge of new technology Diffusion,which has a spatial impact on Farmers' adoption of new technology.In freshwater aquaculture water microbial technology as an example,based on survey data of village households docking,using spatial Durbin model to empirically test the impact of aquaculture agglomeration and technical support embedded in the main of technology adoption,the main conclusions are:the village level farmers overall technical input intensity and there are significant differences in mastering the technical level;farmers using microbial profile water technology and master the knowledge of information technology in the adjacent village had a significantly positive spatial correlation;the spread of culture agglomeration can only promote knowledge of information technology in the village space,then the positive influence the village farmers' adoption of space technology strength;dissemination of public technology embedded in the main breeding agglomeration can only promote knowledge of information technology in the village space then,a significant positive effect in village farmers' adoption of technology strength;the main profit technology promotion Culture can promote the dissemination of knowledge embedded cluster technology information in the village and neighboring villages,so as to promote the knowledge of information technology to produce spatial direct effect and indirect effect on technology adoption behavior.According to the above conclusions and puts forward corresponding countermeasures and suggestions are as follows:(1)the importance of information literacy plays an important role in the promotion of new agricultural technology,improving the farmers'ability to accept and identify information,and to transmit information to farmers knowledge in patience in the promotion process;(2)pay attention to the social network plays an important role in information technology communication,maintain the harmony and stability of rural society makes the local acquaintance network continue to play a role in the new era,and actively expand the social network to obtain more differentiated information,grass-roots governments should play a role as a bridge in the process of expanding the social network of farmers,especially for farmers and technical support for the organization of the main creation more opportunities;(3)with the development of comparative advantage of agricultural industry agglomeration,actively cultivate the main technical support,so that both end The rural market has enriched the farmers' social network and made the network play a synergistic role in the process of marketization.
