新型城镇化的关键是城镇化质量的提升，流动人口的幸福感水平是城镇化质量评价的重要维度。鲜有研究基于地理学视角，探究流动人口幸福感的空间分异特征和影响机制。本研究旨在揭示中国流动人口幸福感水平的空间分异规律，阐明城市微观地理环境对流动人口幸福感的影响机制，并探索短期和长期空间行为所造成的微观地理环境变化对流动人口幸福感的影响。具体而言，研究将基于全国性大规模调查数据和广州市实地调查数据，利用多层级回归、结构方程模型、固定效应回归、质性分析法和GIS空间分析技术，阐明所居住社区的微观地理环境、家外日常活动空间的微观地理环境、迁移和迁居事件及其所造成的微观地理环境变化对流动人口幸福感的影响机制。研究计划揭示主客观微观地理环境对幸福感的效应，同时采用以人为本和动态追踪的视角，把地理环境的时空变化纳入到分析框架中，解决同类研究的地理背景的不确定性问题。研究可为城镇化政策制定和幸福城市建设提供科学依据。

Improving the quality of urbanisation is essential to China’s new-type urbanisation. The evaluation of the quality of urbanisation depends on the level of migrants’ subjective wellbeing. Little research has been done to investigate the spatial variation in migrants’ subjective wellbeing and its determinants in the Chinese context. This study aims to add a geographical dimension to our understanding of migrants’ subjective wellbeing (1) by revealing the spatial pattern of migrants’ subjective wellbeing at multiple geographical scales, (2) by examining the spatiotemporal effects of microscopic geographic context on migrants’ subjective wellbeing, and (3) by exploring the effects of everyday activities, migration, and residential mobility and resultant contextual changes on migrants’ subjective wellbeing. Empirically, based on nationally representative data (i.e. Chinese Family Panel Survey, Chinese Labor-Force Dynamic Survey, and National Migrant Population Dynamic Monitoring Survey) and first-hand Guangzhou survey data, this study will examine the mechanisms through which the microscopic geographic context of residential neighbourhoods, the microscopic geographic context of everyday activities, and the contextual change due to important life events (in particular, migration and residential mobility) influence migrants’ subjective wellbeing, using the combination of qualitative and quantitative methods such as multilevel regressions, structure equation models, fixed-effect regressions, qualitative methods, and GIS spatial analysis techniques. This study will contribute to our understanding of migrants’ subjective wellbeing in Chinese cities not only by unraveling the effects of microscopic geographic context in both objective and subjective senses on individuals’ subjective wellbeing, but also by incorporating the spatiotemporal dynamics of contextual influences into the analytical framework. In this sense, this study will address the Uncertain Geographic Context Problem (UGCoP) arising from examining the effect of environmental exposure on individuals' health and wellbeing outcomes from a people-based and longitudinal perspective. It will also have policy implications in terms of China’s new-type urbanisation and the agenda for building ‘happy cities’.
