农户间知识共享与农业技术扩散对农业科技成果转化具有重要意义。首先，通过两个典型案例的实地访谈，对农户参与下的农业科技成果转化系统进行质性分析，明确农户及其知识共享行为在农业科技成果转化中的重要作用。其次，通过文献分析筛选农户间知识共享的影响因素，采用ISM方法确定影响因素的作用路径结构。将影响因素参数化，用于博弈建模，探索农户间知识共享的机理。再次，理论探讨农户间知识共享与农业技术扩散的耦合关系，并对二者的关系进行拟合和验证。为了进一步探讨基于农户间知识共享的农业技术扩散机理，建立系统动力学模型并进行基模分析和仿真试验。最后，分析农户间知识共享、农业技术扩散和农业科技成果转化三者间的关系，提出假设，建立结构方程模型。在对案例中参与农户进行大样本问卷调查的基础上，搜集数据并进行模型拟合，测量农户间知识共享对农业科技成果转化的促进作用，以及农业技术扩散的中介作用。以此为据，设计策略体系。

Knowledge Sharing among Farmers (KSF) and Agricultural Technology Diffusion (ATD) are important to Agricultural Sci-tech Achievements Transformation (ASAT). First,based on face-to-face interview of two typical cases,qualitative study will be done to analyze the ASAT system which is involved in farmers, to explore the important role of the farmers and their knowledge sharing behaviors in the process of ASAT. And then, the influencing factors of KSF will be selected by literature review and structured by ISM method. Game models of KSF are going to be constructed to explore the mechanism by introducing parameterized influencing factors. Futhermore, the coupling relationship between KSF and ATD is disscussed, fitted and verified. In order to further analyze ATD mechanism on the basis of KSF, a System Dynamic Model is built, following by archetype analysis and simulated test. Finally, the relationship among KSF, ATD and ASAT will be analyzed, and a Structure Equation Model will be built on the basis of relationship hypotheses. A large sample data will be collected by questionnaire survey of farmers. Through fitting of model, the acceleration impact from KSF to ASAT and intermediation of ATD will be measured. On this basis, a strategy system will be designed to enhance KSF and ATD, and in turn the ASAT.
