中文摘要：

本研究在劳动负效用视角下，通过构建退耕农户决策模型研究退耕还林成果的可持续性问题。引入劳动负效用概念构建农户决策的基本模型。并通过拓展的模型分析农户的生态林管护概率、林产品的市场化程度以及家庭成员劳动就业结构与真实劳动报酬的关系。研究表明：退耕还林成果能否持续，主要取决于退耕农户参与工程的真实劳动报酬。

英文摘要：

In this paper the sustainability of China＇s Cropland Conversion Program is studied by a se- ries of models of farmer＇s decision-making from the perspective of labor disutility. The paper establi- shes a basic farmer＇s model based on the concept of the labor disutility, and analyzes the relationship between real labor remuneration and parameters such as probability of farmer＇s management and protec- tion of converted ecological forest, market-oriented degree of demand for the forest products and the job structure of farmer＇s family members through an extended model. It is concluded that the sustain- ability of converted forests＇performance depends mainly on the farmers＇ motivation to the Program through the analysis of the relationship between the former parameters and the real labor remuneration.
