农地经营权抵押在落实“三权分置”理论指导实践和加快农村金融创新方面意义重大。本项目立足于中国农地经营权抵押试点的基本事实，在结合产权、行为经济学及金融约束理论的基础上，构建用于分析农地经营权抵押约束的理论框架和研究方法体系。基于17省份试点区一手调查数据，以权属来源、用途特性及经营规模三个要素为切入点，从金融需求方视角现实观察和实证分析农户三个要素与其抵押融资决策、金融约束的内在关联性，解析判明关键视角，阐述评价抵押贷款政策缓解农户融资约束的有效性。按照三个要素及抵押需求筛选样本农户，联合调查地农村金融机构，采用实验经济学方法从金融供给方视角检验农户三个要素与金融机构抵押贷款供给约束的联动影响，对比分析实验结果和现实观察，揭示阻碍金融机构抵押贷款有效供给的根源及决定要素。最后，基于项目成果和国内外经验，为提升农地金融强农惠农富农的有效路径，以及深入推进农地经营权抵押贷款试点提供政策建议。

It is of great significance for implementing the theory of "Separation of Three Rights" to guide the practice and accelerating the rural financial innovation. Basing on the basic facts of land-using rights' mortgage in pilot areas of China, and combing property rights, behavioral economics and financial constraint theory, the project constructs theoretical framework and research methods for analyzing financial constraints of land-using rights' mortgage. Using first-hand data collected from pilot areas of 17 provinces, and considering origin of ownership, usage characteristics and business scale as important viewpoints, the project is going to observe and analyze the internal correlation between the three factors and financing decisions and financial constraints from the financial demand side perspective in order to judge the key important factor and evaluate the mortgage policy to alleviate the effectiveness of financing constraints of rural households. Selecting sample farmers according to the three elements and mortgage demand and combining with the investigation of rural financial institutions, the project also explores correlative effects between three factors and credit rationing of financial institutions from the perspective of financial suppliers by using methods of experimental economics. Comparing the experimental results and combing with practical observation, the project pursues to reveal the origin of determining factors which hinder the effective supply of mortgage loans of financial institutions. Finally, basing on the empirical results and experiences of both here and abroad, the project would like to give some policy suggestions for improving effective path so as to strengthen agriculture, benefit farmers, and raise rural living standards, meanwhile, to further promote the process of pilot about the mortgage loan of land-using rights.
