对退耕还林中农民选择权认识的经济学分析

农户决策行为和反应机制无疑是考察项目可持续性的一个重要方面。本文应用微观经济学理论．结合退耕还林工程的实际情况．提出理论假说：贫瘠土地退出种植是经济发展到一定水平的自发结果。并根据三省遐耕还林的实际调查数据。采用计量模型对退耕还林农户选择权认识问题进行检验。研究结果表明退耕还林工程的可持续性还存在一定隐患，退耕还林工程不仅要和当地的经济发展紧密结合。在操作方法上还需进一步改进。

Examination of the Choice Cognizance for Farmers in Grain for Green Project from Economics Perspective

No doubt that the responsive and decisional procedures of rural household determine the sustainability of a project. Applying microeconomics theory, we put forward the hypothesis that it will be a natural mechanism for farmers with high opportunity cost to quit planting on barren land. Using the survey data in three provinces and the econometrical model, we analyze the choice cognizance of participants in Grain for Green project. Our result shows sustainability is still a problem for the project. We also provide some advice to solve the problem.
