Introduction: The Scope of Urban Sociology
---
城市是人类文明最引人注目的创造物之一。从美索不达米亚平原上最早的城市雏形，到今天纽约、东京、上海等超级大都市的崛起，城市不仅是人口与建筑的简单集聚，更是社会关系、文化生产与经济活动的复杂综合体。在全球范围内，超过55%的人口如今居住在城市之中，而这一比例预计将在2050年达到68%。这一前所未有的城市化进程，使得理解城市——它的结构、功能、问题与可能性——成为当代社会科学最重要的课题之一。城市社会学（Urban Sociology）正是为这一理解提供系统理论视角与分析工具的专门学科。
Urban life represents one of humanity's most remarkable achievements. From the earliest urban settlements on the Mesopotamian plains to the rise of contemporary megacities like New York, Tokyo, and Shanghai, cities are not merely concentrations of population and architecture but complex assemblages of social relations, cultural production, and economic activities. Globally, more than 55 percent of the world's population now lives in urban areas, a proportion projected to reach 68 percent by 2050. This unprecedented wave of urbanization renders the systematic understanding of cities—their structures, functions, problems, and possibilities—one of the most pressing intellectual challenges of our time. Urban Sociology is the specialized discipline that provides this understanding with rigorous theoretical frameworks and analytical tools.
本章将带领读者系统地进入城市社会学的知识世界。我们将首先澄清城市社会学的研究对象与核心议题，继而追溯这一学科从19世纪末萌芽至今的百年发展历程，重点剖析芝加哥学派（Chicago School）对城市研究的奠基性贡献，以及20世纪中叶以来理论视野的多元化拓展。在此基础上，我们将阐明城市社会学与社会学、地理学、城市规划等相邻学科的交叉关系，揭示其独特的问题意识与解释逻辑。最后，本章将勾勒本书的整体理论框架与篇章结构，帮助读者建立对这一知识领域的全景式认知。
This chapter serves as a gateway to the intellectual world of urban sociology. We begin by clarifying the discipline's research objects and core concerns, tracing its development from its late nineteenth-century origins to the present day. A central focus is the foundational contribution of the Chicago School, followed by an examination of theoretical diversification since the mid-twentieth century. We then articulate urban sociology's relationships with neighboring disciplines—general sociology, geography, urban planning, and anthropology—highlighting its distinctive problematic and explanatory logic. The chapter concludes by outlining this book's overall theoretical framework and chapter structure, providing readers with a comprehensive map of the discipline.

一、城市社会学的学科界定 | Defining Urban Sociology
1.1 研究对象的确定 | Establishing the Research Object
城市社会学的研究对象并非城市本身这一静态的空间容器，而是城市作为社会生活的组织形式——即城市如何塑造人的行为、认同与社会关系，以及这些社会过程如何反过来建构和改变城市空间。这一界定区分了城市社会学与纯粹关注物质空间形态的城市地理学或城市规划学，尽管这些学科之间存在大量交叉地带。
The research object of urban sociology is not cities as static spatial containers but rather cities as forms of social organization—how urban environments shape human behavior, identity, and social relations, and how these social processes in turn construct and transform urban space. This definition distinguishes urban sociology from disciplines focused purely on material-spatial forms, such as urban geography or urban planning, although significant overlaps exist among these fields.
具体而言，城市社会学关注的核心问题可以归纳为以下几个层面。首先是城市化的宏观进程，即人口从农村向城市的转移、经济活动向城市的集聚、以及由此引发的社会结构变迁。其次是城市内部的社区与邻里关系，包括不同社会群体在城市空间中的分布模式、居住分异（residential segregation）与社区演替（neighborhood succession）机制。第三是城市社会问题，如贫困集中、犯罪、住房短缺、环境不公等城市病的成因与治理。第四是城市文化与日常生活，探索城市生活方式、亚文化、消费实践与集体记忆的建构。第五是城市治理与城市运动，研究城市政治、公民参与以及居民为争取空间正义而进行的抗争。
Urban sociology's core concerns can be organized around several interrelated levels. First, there is the macro-level process of urbanization—the movement of population from rural to urban areas, the concentration of economic activities in cities, and the resulting transformations of social structure. Second, urban sociology examines community and neighborhood relations within cities, including patterns of spatial distribution among different social groups, mechanisms of residential segregation, and processes of neighborhood succession. Third, the discipline addresses urban social problems—the causes and remediation of urban pathologies such as concentrated poverty, crime, housing shortages, and environmental injustice. Fourth, urban sociology explores urban culture and everyday life, investigating urban lifestyles, subcultures, consumption practices, and the construction of collective memory. Fifth, the field examines urban governance and urban movements, studying city politics, civic participation, and residents' struggles for spatial justice.
1.2 核心概念与分析单元 | Core Concepts and Units of Analysis
理解城市社会学需要掌握若干关键概念。城市化率（urbanization rate）指城市人口占总人口的百分比，是衡量一个国家或地区城市化程度的 기본指标。城市体系（urban system）则关注不同规模城市之间的关系网络，探讨首位城市（primate city）与功能性城市层级（functional hierarchy of cities）的形成机制。
A thorough grasp of urban sociology requires familiarity with several foundational concepts. Urbanization rate refers to the percentage of population residing in urban areas, serving as a basic indicator of urbanization level. The urban system concept examines relationships among cities of different sizes, exploring the formation mechanisms of primate cities and functional urban hierarchies.
在城市内部层面，居住分异描述了不同社会群体基于阶层、种族、族群等身份标识在城市空间中形成相对隔离的居住格局。这一概念与邻里效应（neighborhood effects）密切相关，指个体所处的邻里环境如何影响其教育获得、就业前景、健康状况等生命历程结果。绅士化（gentrification）是另一个核心概念，描述了城市社区因中产阶级或上层阶级的进入而导致的物质环境改善与社会结构变迁过程，尽管这一过程往往伴随着原有低收入居民的 displacement（置换）。
At the intra-urban level, residential segregation describes the relatively separate residential patterns of different social groups based on class, race, ethnicity, and other identity markers. This concept connects closely to neighborhood effects—the mechanisms through which local environments shape individual life outcomes in education, employment, health, and beyond. Gentrification represents another central concept, describing the material improvement and social transformation of urban neighborhoods resulting from the influx of middle-class or upper-class residents, often accompanied by the displacement of original low-income inhabitants.
城市社会学的主要分析单元包括个人与家庭、社区与邻里、城市区域以及城市体系等不同层次。这种多层次分析框架使得研究者能够同时关注个体选择与结构约束、微观互动与宏观变迁之间的复杂关联。
Urban sociology employs multiple units of analysis, ranging from individuals and households, to communities and neighborhoods, to urban regions, to urban systems. This multi-level framework enables researchers to examine the complex interactions between individual agency and structural constraints, micro-level interactions, and macro-level transformations.
1.3 学科定位与学术谱系 | Disciplinary Position and Academic Lineage
城市社会学是社会学的子学科之一，同时也与社会科学中的诸多领域存在深刻关联。在学科分类体系中，城市社会学归属于社会学的经验研究领域（empirical fields of sociology），与经济社会学、政治社会学、文化社会学等并列。然而，与这些子学科通常围绕特定社会现象领域（如经济、政治、文化）进行界定不同，城市社会学采取的是空间视角（spatial perspective）——它追问空间位置、空间组织与空间过程如何影响社会生活的各个面向。
Urban sociology occupies a position as a subdiscipline of sociology while maintaining deep connections with numerous other fields in the social sciences. Within disciplinary taxonomies, urban sociology belongs to the empirical fields of sociology, alongside economic sociology, political sociology, and cultural sociology. However, unlike these subdisciplines, which are typically organized around specific social domains (economy, politics, culture), urban sociology adopts a spatial perspective—examining how spatial location, spatial organization, and spatial processes shape diverse aspects of social life.
这一学科定位赋予城市社会学独特的学术气质。它既需要理解社会结构与文化意义的生产机制（这是所有社会学分支的共同追求），又需要将空间维度系统地整合进社会分析之中。这使得城市社会学家往往需要跨越学科边界，与地理学家、历史学家、人类学家、政治科学家以及城市规划师进行对话与合作。
This disciplinary position confers a distinctive intellectual character upon urban sociology. The field must simultaneously understand the mechanisms of social structure and cultural production (the common quest of all sociological subdisciplines) while systematically integrating spatial dimensions into social analysis. This renders urban sociologists frequently compelled to cross disciplinary boundaries, engaging in dialogue and collaboration with geographers, historians, anthropologists, political scientists, and urban planners.
