住宅用地多主体供应下利益相关者福利均衡及其调控研究

The research on the welfare of the stakeholders is an important part of the reform of urban land system in China. Taken Shanghai, Nanjing, Zhengzhou, Wuhan and Chengdu as research region, and based on field survey, problem analysis, theoretical explanation and mechanism discussion, this project will analyze the change of the distribution pattern of the residential land supply main body, and construct an analytical framework based on the welfare balance of the stakeholders. Then, the project will identify the core stakeholders in the supply process of residential land in different areas, and the characteristics of the subject's behavior, income distribution and interest demands will be analyzed. Further more, different welfare measures are adopted for different stakeholders to reveal the welfare balance among different stakeholders. Finally, by means of measurement and case analysis, the influence mechanism of the behavior response and welfare changes of different stakeholders will be analyzed. On the basis of previous studies, the project will put forward relevant policies and suggestions to improving the path of differentiated benefits for different stakeholders. The research results are of great theoretical significance for understanding the relationship between the change of the supply subject of residential land and the welfare balance of the stakeholders, and the establishment of a coordinated urban and rural construction land supply market. In order to balance the distribution of interests among stakeholders, it is necessary to realize the unification of the allocation efficiency and fairness of land elements.

住宅用地多主体供应下的利益相关者福利研究是当前我国城镇土地制度改革的重要内容。本项目以上海市、南京市、郑州市、武汉市、成都市为研究区域，通过实地调查、问题分析、理论阐述和实证探索，剖析住宅用地供应主体变化引起利益分配格局变化，构建以利益相关者福利均衡为核心的分析框架；在不同地区住宅用地供给过程中识别核心利益相关者，分析主体行为特征、收益分配状况及其利益诉求；针对不同利益相关者采用不同福利测度方法，揭示不同利益相关者之间福利均衡关系；采用计量和案例分析方法，分析不同利益相关者行为响应及其福利变化的影响机理。在此基础上，提出针对不同利益相关者差异化福利改善路径，提出相关政策建议。研究成果对于认识住宅用地供应主体变化与利益相关者福利均衡关系，建立城乡统筹的建设用地供应市场具有重要的理论指导意义；对于平衡利益相关者之间的利益分配关系，实现土地要素配置效率与公平的统一，具有积极的实践指导意义。
