农村土地整治PPP模式的减贫机理、效应及政策响应

This project focuses on poverty alleviation of the PPP mode of rural land consolidation. Based on the study of the relationship between interested groups, we aim to find out the poverty alleviation mechanism,the sustainable and multidimensional poverty alleviation effect as well as the implementing obstacles and the responsive policies. Firstly, we look into the long term equilibrium condition under which the interested groups in PPP mode of rural land consolidation can keep stable relationship using the methods of social network analysis and game theory. Then, we reveal how PPP mode of rural land consolidation can alleviate poverty problems applying structural equation model, the method of comparative analysis as well as the sustainable livelihoods framework put forward by DFID. What's more, we measure the poverty alleviation effect of the PPP mode of rural land consolidation using PSM-DID and make a comparison to other modes. Meanwhile, the threshold effects are revealed based upon farmers heterogeneity and we explore that to which extent that different kind of farmers are sensitive to this mode when increasing poverty standards. Next, obstacle factors and obstacle amounts are evaluated using and S-D evidence synthesis theory. Utilizing empirical analysis, we look into how the obstacles differ when landform and poverty level changes and the causes. Finally, responsive policies are proposed according to the fore-mentioned research.

本课题以农村土地整治PPP模式扶贫问题为研究对象，在探究农村土地整治PPP模式利益主体间关系基础上，研究其减贫机理、可持续多维减贫效应、在贫困地区推行的障碍及政策响应机制。首先，采用社会网络分析法和博弈论研究各类农村土地整治PPP模式利益主体间关系长期稳定的均衡条件；其次，运用DFID的可持续生计框架、结构方程模型和比较分析法揭示农村土地整治PPP模式的减贫机理；然后，运用匹配倍差法测度农村土地整治PPP模式可持续多维减贫效应并与其它模式进行比较，基于农户异质性研究农村土地整治PPP模式减贫的门槛效应，并探索贫困标准提高后各类农户对农村土地整治PPP模式减贫效应的敏感性；接着，运用吻合因子排序法和S-D证据合成理论研究农村土地整治PPP模式在贫困地区推行的障碍因子及障碍度，实证分析不同地貌形态、不同贫困程度地区推行障碍的差异及成因；最后，根据前面研究的结论，设计政策响应机制。

课题组在湖北、贵州、湖南、广西等省份，对农村土地整治相关部门工作人员、贫困地区典型项目的农户进行了面对面访谈式调查，共获得有效问卷877份，并针对上述省份多个不同整治模式项目区进行了实地调查和案例分析。2018-2022年已发表期刊论文13余篇；已完成硕士学位论文5篇，即将完成硕士学位论文2篇、博士学位论文1篇。本课题以农村土地整治PPP模式扶贫问题为研究对象，在探究农村土地整治PPP模式利益主体间关系基础上，研究其减贫机理、可持续多维减贫效应、在贫困地区推行的障碍及政策响应机制。首先，采用社会网络分析法和演化博弈模型研究各类农村土地整治PPP模式利益主体间关系长期稳定的均衡条件；其次，运用DFID的可持续生计框架、结构方程模型和比较分析法揭示农村土地整治PPP模式的减贫机理；然后，利用农户实地调研数据和匹配倍差法测度农村土地整治PPP模式可持续多维减贫效应并与其它模式进行比较，基于农户资源禀赋异质性和fsQCA方法研究农村土地整治PPP模式减贫的门槛效应，并探索贫困标准提高后各类农户对农村土地整治PPP模式减贫效应的敏感性；接着，运用吻合因子排序法和S-D证据合成理论研究农村土地整治PPP模式在贫困地区推行的障碍因子及障碍度，实证分析不同地貌形态、不同贫困程度地区推行障碍的差异及成因；最后，根据前面研究的结论，设计政策响应机制。
