基于学术界共识的后工业化大城市社会空间中产阶层化的理念,本文首次提出社会阶层化的概念并指出社会阶层化主要研究在社会阶层的生活行为扩散和变化规律下,所构建的城市日常居住社区体系和日常生活行为场所体系的时空模式,以此探讨城市社会空间结构的变化。研究认为不同城市发展阶段其对应有不同主导阶层的社会阶层化空间结构。进一步从解构城市社会空间结构的演化动态角度,研究不同社会发展阶段下,社会阶层化与城市娱乐产业的对偶空间结构关系。

Urban space is the product of society, and its form and process are shaped by the dynamic evolution of the whole social structure. Urban (social) space construction in different development stages is the space result of the building of the leading class in this stage for social and economic aim. Entertainment industry of city is the dynamic industry system of reflecting energy and sustainable development of big city in post-industrial era. Its place structure is the symbol of urban residential living space quality. The layout of entertainment places is restricted by the classification location relation.
Based on the common cognitive concept of social space gentrification of Post-industrial big city in academic circle, the authors first explained social classification in this paper. The main research content of social classification in the urban social geography is under the rule of social class living behavior diffusion and change, the time-space pattern of urban daily residential community system and urban daily living behavior place system are constructed, and the authors investigate the change of urban social space structure. The social classification space structure with different leading class exists in different development stage of the city. This paper tries to study the dual space structure relationship between social classification and entertainment industry of city in different social development stages from the angle of the dynamic evolvement of urban social space structure.
This paper has drawn several conclusions: 1)Social economy development level and stage accompany the spatial succession of social class differentiation and social classification, under the restriction of above law, time-space sequence differences occur in all kinds of living behavior space types and constitutional life styles, which result in differences of social classification in the space structure of living consumption behavior places. 2)As an important stable factor in modern society, middle class has a dominant effect on the reconstruction of urban social space structure. Not only does gentrification increasingly become a positive urban development strategy, but also it is the trend of improving the spatial quality of urban life. 3) Entertainment industry (space) of city gives city the rich culture meaning besides economy meaning, and is the important content of residents' life spatial quality in post-industrial era. The rule of social classification causes that the space structure of commercial amusement place presents the distribution pattern of stylization and hierarchy.
