| At present,under the constraints of resources and environment,the green and sustainable food production has become an important issue of concern to our government.As the main body of grain production,farmers ’ adoption of green production technology is the key to the green transformation of grain production.However,as a new technology with more investment and slow effect,grain green production technology is generally ignored by ’ rational small farmers ’.Therefore,in order to promote farmers to adopt grain green production technology,it is necessary for the government to intervene to a certain extent,and it also helps to solve the threshold problems of funds and technology faced by farmers.Unfortunately,although the government strongly supports and promotes grain green production technology,the enthusiasm of farmers is not high,and the willingness to continue to adopt is not strong.In addition,for China,a country with complex relationship network,the mechanism of resource allocation relying on clan and kinship is still playing a relatively large role,and farmers ’ behavior decisions are often embedded in the relationship network and affected.Therefore,in the process of promoting farmers ’adoption of grain green production technology,in addition to relying on the role of government promotion,it is necessary to pay attention to the function of farmers ’ own relationship network.However,the existing research on how to more effectively play the role of government promotion and relationship network in promoting the green transformation of food production is not deep enough,and the answer to this question can provide reference for the government to improve the way of promotion,improve the efficiency of promotion and achieve the ultimate goal of green food production.In this thesis,787 farmers in six major grain producing areas of Shandong,Hebei,Jiangsu,Anhui,Hubei and Jiangxi were selected as the main research objects.Starting from the way of policy promotion,and according to the special reality of China ’ s rural human relations system,along the basic ideas of farmers ’ information collection,acceptance,adoption methods and evaluation of the adoption effect of key technologies of grain green production,based on farmers ’ behavior decision theory,agricultural technology promotion theory,trust theory and social relationship network theory,the influence mechanism of different social relations networks on farmers ’ adoption of key technologies of grain green production was analyzed in depth.And the role of heterogeneous network in government promotion affecting farmers ’ adoption behavior is different,and then the orderly probit and tobit model is used for empirical analysis.Details and conclusions are as follows :1.The influence of government promotion on farmers ’ adoption of green grain production technology : Based on the top-down promotion model of government,taking the decision-making process of farmers ’ adoption behavior as the direction and combining with the trust mechanism theory,this thesis puts forward the influence mechanism of farmers ’ adoption through government promotion to improve the degree of adoption,adapt to agricultural modernization to change the way of adoption and improve the evaluation of adoption effect.That is mainly due to the government promotion of free,reliability and integrity,to a certain extent,can improve farmers ’ green cognition to improve the degree of adoption and enrich the way of adoption,at the same time,the government promotion is deeply recognized by farmers can ensure the sustainability of farmers ’ adoption behavior.The conclusion of the empirical analysis shows that the impact of government promotion on farmers ’ adoption behavior is not significant,which is in line with the current situation of government promotion.The possible reason is that government promotion ignores the national conditions of“small farmers in big countries”and forms a bad cycle of resource "big farmers ".In order to improve the efficiency of government promotion,this thesis examines another major source of information for small farmers — relational network.2.The influence of social network on farmers ’ adoption behavior of grain green production technology : Based on social network theory,technology diffusion theory and farmers ’ behavior decision theory,this chapter discusses the influence of heterogeneous social network on farmers ’ adoption behavior of grain green production technology.That is,as a channel for farmers to obtain information,the relationship network can affect farmers ’ adoption behavior by improving farmers ’ cognition,reducing information asymmetry,reducing costs and providing opportunities for cooperation,reciprocity and mutual learning.The different strength of the relationship network has different effects on influencing farmers ’ adoption of grain green production technology,enriching adoption methods and improving adoption effect evaluation.The empirical results show that both strong relationship network and weak relationship network have significant influence on farmers ’ adoption behavior of grain green production technology.3.The moderating effect of relationship network on government promotion on farmers ’ adoption behavior of grain green production : Based on the human relationship mechanism and the " embedded structure " theory,this thesis analyzes the relationship between government promotion and relational network as the main channel for farmers to obtain information,and puts forward that government promotion and farmers ’behavioral decisions are embedded in the relational network,regulated by the relational network,and the regulation modes are different in different relational network environments.The empirical results show that the relationship network has a significant moderating effect on the impact of government promotion on farmers ’ green production technology adoption behavior,which provides an improved idea for improving the efficiency of government promotion and promoting farmers ’ green production behavior.At the same time,in different stages of government promotion affecting farmers ’adoption behavior of grain green production technology,the moderating effects of different strong and weak relationship networks are different.The interaction between family network and government promotion has a significant positive impact on farmers ’adoption degree and change of adoption mode.The interaction between general network and government promotion has a significant positive impact on farmers ’ adoption degree,outsourcing degree and adoption effect evaluation.This thesis analyzes the necessity of government promotion and the innegligibility of relationship network by combing the main channel role of affecting the decision-making of small farmers ’ adoption of grain green production technology.Through the mosaic structure theory,government promotion,relationship network and farmers ’ adoption of grain green production technology are included in the unified analysis framework,and the moderating effect of relationship network and the influence of heterogeneous relationship network are empirically proved.Through theoretical research and empirical test,it is concluded that making full use of the regulatory role of small farmers ’ social network and considering the differences of different social networks can put forward another way for policy implementation and put forward policy suggestions for the realization of Chinese green production mode. |
