实现生态移民政策环境保护和反贫困双重目标是公共管理研究亟待解决的重要课题，尤其是究明生态移民与反贫困和环境之间的内在作用机理是重大的科学问题及突破理论瓶颈的关键所在。本项目基于反贫困视角，以微观农户利益最大化为出发点，运用Logistic模型探索农户对生态移民政策的行为响应机理及移民意愿影响因素；采用固定效应估计、一阶差分估计（First Order Differential）及夏普里值分解法（Shapley Value）等模型测算生态移民政策对农户的经济效应并揭示农户收入及其结构的变动规律；运用Probit模型测算生态移民政策的贫困瞄准效率，构建反贫困效率评价机制。本项目的数据来源于陕西省南部地区10县54个村的1614户样本农户及所构建2008-2016年生态移民数据库，并运用访谈法为生态移民政策的实施积累详实的案例资料及实证分析结果，为保障生态移民可持续发展提供理论支撑和政策建议。

Achieving the dual goals of the environmental protection and anti-poverty for ecological immigration policy is an important issue in public management research that need to be addressed, especially, the mechanism of ecological migration on anti-poverty and environment is a major scientific problem and the key to the theory bottleneck breakthrough . Based on the microcosmic perspective of the anti-poverty movement and the maximum benefits of peasant household, this study will compare the different ecological migration policy and implement a field investigation at the rural-level in the south of Shaanxi Province, including 1614 peasant household samples which belong to 54 villages of 20 towns in 10 counties from 2008-2016. By using the time series data gained through the field investigation, this study will adopt the fixed effect model, first order differential model, logistic model and Shapley value decomposition method to analyze the structure of peasant's income, livelihood capital, and income distribution of the migrators. Furthermore, this study will illuminate the responding of the peasant household after implementing the ecological migration policy, and the impact of the ecological migration policy on peasant's income. Meantime, this study will try to construct an index system to evaluating the effect of the anti-poverty movement in rural areas of China, and then calculate the targeting efficiency and poverty reduction of the ecological migration policy in rural areas. At last, this study will propose the suggestions about how to guarantee the sustainable development of the ecological migrators, and make a theoretical foundation for the implementation of ecological migration in the south area of Shaanxi Province.
