在居民生活品质和居住环境受到新一届政府高度重视的背景下，本项目以中国城市不同收入水平、住房产权和户籍条件的家庭为主体，基于居住压力门槛假说，探讨住区环境对居住满意度的影响机理与程度、不同住区环境下家庭居住压力与迁居决策关联性的科学问题。本项目进行综合住区环境要素与家庭异质性的两层级问卷设计和调研，从景观规划、环境安全、公共服务和住区文化四个维度建立住区环境评价指标体系；构建多元排序Probit居住满意度模型，度量影响家庭居住满意度的关键住区环境因素；利用BP神经网络仿真测试家庭居住压力门槛阈值，分析不同类型家庭的居住压力门槛与迁居决策；设计提高城市家庭居住满意度的可行方案，以促进社会融合与城市可持续稳定发展。研究提出居住压力门槛测算方法，拓展了国际学术界关于居住压力与迁居行为的研究路径，在实践上可为政府部门提供方便的人口迁移决策分析工具。

The highlighted resident quality of life and residential environment receive serious attention from the new government in China, which claims of highly importance and serves as the context of this research proposal. This proposal will mainly focus on the subject of family with different income level, property rights and household register in urban China. Based on residential stress threshold hypothesis, this proposal will analyze the mechanism and impact of residential environment to residential satisfaction, and examine the relationship between residential stress in disparate residential environment and residential mobility decision. A questionnaire will be designed centering on two layers of elements-comprehensive resident environmental factors and family heterogeneity, and the data will be gathered through field research. This proposal will devote to using multidimensional factors to establish an assessment index of residential environment, that is, district planning, environment security, public service and residential culture, then build an ordered multivariate Probit model of residential satisfaction and measure the crucial resident environmental factor affecting residential satisfaction. BP neural network simulation method will be used to test the residential stress threshold value, and the residential stress threshold and mobility intention towards disparate types of families will be analyzed. Simultaneously, this proposal will design a feasible program aiming to improve residential satisfaction, ultimately promoting social integration and reducing the costs of city management. Consequently, this proposal will provide a measurement approach for residential stress threshold, and develop the path to study the residential stress and mobility behavior in international academia. In practice, the measurement approach for residential stress threshold designed in this proposal can be used as an useful analysis tool for government to make crucial decisions upon population migration.
