城市社会空间结构历来是城市地理研究的重点之一。转型期我国社会分层和空间分化趋势日益明显，带来新的城市社会空间结构。中产阶层作为城市社会阶层的重要组成部分，具有促进社会经济发展与稳定的重要作用。本项目以中产阶层空间分异为研究主题，在综述国内外相关研究进展的基础上，提出具有中国特色的中产阶层的概念内涵、划分标准，并试图构建具有新的中产阶层理论体系。并以中国改革开放前沿阵地广州市为例，将广州十区两市分为老城区、新城区、近郊区和远郊区四个层次，采用第四次、第五次、第六次全国人口普查数据库中居民委员会尺度的数据，运用统计分析、问卷调查、跟踪访谈和地理信息系统分析方法，从宏观、中观和微观三个层面，就居住区位、就业区位、日常活动、意象空间等方面重点研究转型期广州中产阶层空间分异特征，总结并分析其形成的内生机制和外生机制。最后提出广州中产阶层与城市社会结构的空间调控与制度建设。

In the present transitional period of China, the multi-interests patterns, the division of society and spatial differentiation are becoming obvious, bring new urban social space structure. As an important part of social class, the middle class have a important role in promoting social and economic development and social stability. Based on the spatial differentiation of the middle class, the project tried to build an new middle class theory system..Takes Guangzhou as an example and divides into four levels: new sites, an inner suburban and outer suburbs . Based on the fourth, fifth, sixth national population census database of the residents committee scale data, using statistical analysis, questionnaire survey, tracking interviews and geographic information system analysis method, from the macro level, meso level and micro levels, is living location, location, daily activities, employment aspects such as image space key research transition Guangzhou middle class spacial differentiation characteristics. And then summary and analysis the formation mechanism and exogenous mechanism. Finally puts forward space regulation and system construction between Guangzhou's middle class and the urban social structure.
