农地流转是实现农地规模化经营、农业现代化和解决"三农"问题的重要途径之一，关涉宏观经济效率、社会发展、生态文明与微观乡村治理。课题瞄准农地流转综合效益最大化目标，从广义效益出发，在理论分析基础上，构建一个包含经济效益、社会效益、生态效益和公众满意度的"双SE"框架，对农地流转的效益进行四个维度评价。首先，运用CD变异函数评价农地流转的经济效益；在福利测度基础上运用PDLs模型、门槛模型和SYS-GMM面板模型从三个视角评价其社会效应；基于XL生态服务价值理论和DEA测度生态效益，并解构生态效益；运用费耐尔方法和李克特量表法调查评价公众满意度。在四维评价的基础上，运用因子分析法对农地流转效益进行综合评价，并运用Tobit模型分析其影响因素。基于以上研究，重点探讨农地流转效益的分配和协调、完善农地治权结构、农地流转效益的区域实现、农业经营模式选择四个效益优化路径，并提出相关政策建议。

Farmland circulation that relates to the macro-economy efficiency, social development, ecological civilization and micro-country governance is not only one of the important ways to solve the "the issue of agriculture, rural areas and peasants ", but also to achieve the scale operation of farmland and agricultural modernization. Our research aims at comprehensive benefits maximization of farmland circulation. From the perspective of generalized benefit, we try to build a "double SE" framework that is based on theory analysis, including benefits of economy, society, ecology and public satisfaction, to evaluate the farmland circulation benefits. Firstly, we use the CD variation function to evaluate the farmland circulation economical benefits, apply PDLs model, threshold model and SYS-GMM panel model that are on the basis of welfare measure to evaluate its social effects, assess the farmland circulation ecological efficiency and deconstruct its ecological benefits, on the basis of a eocological service value theory XL and DEA method, and apply Fornell method and Likert scale model to investigate the public satisfaction. On the basis of four-dimensional evaluation, then we make a comprehensive assessment on the farmland circulation benefits by factor analysis, and the influencing factors by Tobit model. From the study above, we concentrate on the allocation and coordination of the farmland circulation benefits, improvement of the structure of farmland governance right, achievement of the regional farmland benefits, choices of the farmland operation modes. Finally, policy suggestions related are put forth.
