Study On Rice Farmer's Decision Of Agricultural Technology Adoption In Jiangxi Province

Based on guarantying nation food security and developing modern agriculture, this thesis regards rice farmers in Jiangxi province, one of main production districts in China, as its research object; makes full use of current research achievements, bases on economy theory, handles with econometrics and psychology, intensely takes these large-scale rice farmers and part-time rice farmers as the centre of research, constructs the decision model of technology adoption of large-scale rice farmers, the decision model of part-time rice farmers technology adoption of joining agricultural technology adoption variant and the intervenient model of policy to technology adoption of these two sort rice farmers, uses micro-data of large sample and many angle of view, positively and theoretically studies the characteristic, decision route and other problems of these two sort rice farmers, and in theory also researches the intervenient function of agricultural technology extension and subside policies, gets some conclusions of research, so as to give government some suggestions.This thesis lies into four parts.The first part includes Chapter 1 and Chapter 2, mainly introduces research background, importance, research ideaes, methods and contents, and synthesizes the research achievements about agricultural technology adoption in developed countries and developing countries, so as to take references to following studies. Meanwhile, points out the theories of stage partition of technology adoption of rice farmers and labor optimal allocation as research supports in theory.The second part includes Chapter 3 and Chapter 4, mainly analyzes large-scale rice farmers'characteristic and influential factors of agricultural technology adoption, and concludes at present the goal of technology adoption of large-scale rice farmers is to pursue more production and higher quality. The channels of getting technology information are by their neighbores and friends, TV and broadcast. By their individual advantages, large-scale rice farmers can take the role of demonstration and leadership of technology adoption. Research result also points out that gender, education and age are not the main influential factors, but size, geography environment and family number greatly affect the technology adoption of large-scale rice farmers.Meanwhile, by theoretical inference and case analysis of technology adoption decision model of large-scale rice farmers, the study result of model testifies that there exists the direct decision route of technology adoption of large-scale rice farmers. That is to say, by technology adoption, large-scale rice farmers can improve the production and quality of rice, so as to get the optimum of agricultural income.The third part includes Chapter 5 and Chapter 6, mainly analyzes the characteristic of part-time rice farmers technology adoption. Research result points out part-time rice farmers want to deal with rice production so as mainly to guaranty themselves rice demands. The main target of technology adoption is to save their time, labor and money. The main channels of getting technology information are neighbores and friends, TV and professional corporation organizations. The revenue from rice production is not the main resource of their family income. By joining professional corporation organizations, part-time rice farmers do not only pay attentions to the direct rice income from technology adoption.Meanwhile, based on construction and inference of the decision model of part-time rice farmers'technology adoption of joining agricultural technology adoption variant, this thesis uses entity and time fixed effect model to analyze static influence and dynamic effect of technology adoption to their family income, so as to testify the existence of the indirect decision route of agricultural technology adoption to the increase of part-time rice farmers'family income. That is to say, part-time rice farmers probably adopt saving-time or saving-labor agricultural technology to improve their off-farm income so as to increase their family income.The fourth part includes Chapter 7 and Chapter 8, by model analysis on the intervenient function of agricultural technology extension and subside policies, this thesis points out agricultural technology extension policies can in efficiency enhance technology adoption of large-scale rice farmers and improve society welfare, but not necessarily enhance technology adoption of part-time rice farmers and improve society welfare. As for part-time rice farmers, it is uncertainty of function of agricultural technology information service, and under the condition of boundary income of technology adoption exceeding supply cost of technology, agricultural technology guidance and training can enhance technology adoption and improve society welfare. Meanwhile, subside policies only can improve agricultural technology adoption of large-scale rice farmers, but not necessarily increase the net welfare of society. As for part-time rice farmers, subside policies also can improve their agricultural technology adoption, and under the condition of boundary income of technology adoption exceeding supply cost of technology, subside policies can improve the net welfare of society.Based on the study conclusions of characteristic, decision route of these two sort rice farmers and intervenient function of these two sort policies, this thesis points out government should take different policies for different rice farmers. As for large-scale rice farmers, it is necessary of both greatly implementing agricultural technology extension policies and subside policies. Agricultural technology extension policies should be taken by the direction of technology demand of large-scale rice farmers, and be made full use of their demonstration and leadership function. And government also should enhance subside policies, especially the increasing quantity of subside. As for part-time rice farmers, although it is also necessary of both implementing agricultural technology extension policies and subside policies, it should emphasize on agricultural technology guidance and training, and subside policies are to be given to part-time rice farmers a policy sign of technology adoption and stabilization of rice production.This thesis innovatively analyzes some important problems of rice farmers'technology adoption.In detail: Firstly, based on statistic analysis on characteristic of technology adoption both of large-scale rice farmers and part-time rice farmers, by modified and perfect economy and econometrics models, this thesis testifies the existence of direct decision route of large-scale rice farmers'technology adoption, and finds out indirect decision route of part-time rice farmers'technology adoption. It makes this thesis the innovation of theoretical points.Secondly, by constructing intervenient model of policy to technology adoption, this thesis analyzes the function of agricultural technology extension policies and subside policies to these two sort rice farmers, including both the function to technology adoption and society welfare. It makes this thesis important referenced value of policies.Thirdly, this thesis emphasizes the combination of theoretical and positive analysis, and the micro-data of large sample and many angle of view are adopted in econometric analysis, especially econometric model of technology adoption decision of part-time rice farmers is based on combination of static analysis and dynamic analysis.
