第一章 城市社会学的诞生：从芝加哥学派到全球叙事

1910年冬末的芝加哥，第19区的波兰移民聚居区还浸在五大湖吹来的湿冷里。罗伯特·帕克裹着磨起球的羊皮大衣，跟着简·亚当斯穿过巷口堆着酸菜桶和煤灰的窄路时，刚下班的钢铁工人正扛着焊枪从工厂涌出来，卖波兰香肠的小推车飘着热气和蒜香，远处突然传来玻璃瓶砸在墙上的脆响——两个身着工装的小伙子正带着各自的帮派对峙，手里的铁棍在阴天里闪着冷光。亚当斯刚要上前劝阻，帕克却伸手拉住了她：“别急，我们先听听他们为什么打。”[^1]

In the late winter of 1910, Chicago’s 19th Ward Polish immigrant enclave was still soaked in the damp cold blowing off Lake Michigan. Robert Park, wrapped in a frayed sheepskin coat, followed Jane Addams through the narrow alley piled with sauerkraut barrels and coal dust, as steel workers just off their shifts poured out of the factory, carrying welding torches. The hot, garlic-scented steam drifted from the Polish sausage food cart, when suddenly the crisp sound of a glass bottle hitting a wall rang out in the distance — two young men in work clothes were facing off with their respective gangs, iron bars glinting coldly in the overcast light. Addams was about to step forward to stop them, but Park held her back: “Wait, let’s first hear why they’re fighting.”[^1]

几分钟后，两个帮派的头目坐在巷口的台阶上，手里攥着帕克递的香烟，说出了真相：前一天工厂裁员200人，管理层故意把裁员名额分配给波兰籍和意大利籍工人，还私下给两个帮派的小头目塞钱，让他们煽动手下互相指责是“外族人抢了工作”。这两个帮派的成员其实都是同一个钢铁厂的工人，每月工资只有18美元，一半要寄给老家的亲人，剩下的钱刚够付过渡带的房租。亚当斯后来在 Hull House 的记录里写道：“那天我第一次意识到，所谓的‘移民犯罪’，根本不是 immigrant 的道德问题，而是空间、资本、权力三者绞杀出来的结果。”[^2]

A few minutes later, the two gang leaders sat on the alley steps, holding the cigarettes Park had handed them, and revealed the truth: the day before, the factory had laid off 200 workers, and management deliberately allocated the layoff quotas to Polish and Italian workers, and secretly gave money to the small bosses of the two gangs to incite their men to blame each other for “foreigners stealing jobs”. The members of the two gangs were actually workers from the same steel mill, earning only $18 a month, half of which was sent to relatives back home, and the rest was just enough to pay the rent for the transitional zone. Addams later wrote in her Hull House records: “That day I realized for the first time that so-called ‘immigrant crime’ is not a moral problem of immigrants at all, but the result of the entanglement of space, capital, and power.”[^2]

这个发生在芝加哥第19区的场景，正是城市社会学这门学科诞生的起点。在此之前，社会学的研究大多停留在书斋里，讨论抽象的群体、制度、道德问题，而帕克、亚当斯这些芝加哥学派的学者，第一次把城市当成了“社会实验室”，把自己浸入移民社区、贫民窟、犯罪高发区的日常里，用参与观察的方法捕捉空间里隐藏的社会结构。他们的研究第一次证明：城市的空间布局不是自然形成的，而是不同群体在资本和权力的博弈中不断重构的结果，空间本身就是一种社会产品，承载着不平等、冲突与正义的可能。这正是城市社会学区别于普通社会学的核心标志，也是本书全部分析的理论原点。

This scene that took place in Chicago’s 19th Ward is exactly the starting point for the birth of urban sociology as a discipline. Before this, sociological research mostly stayed in studies, discussing abstract groups, institutions, and moral issues. Scholars of the Chicago School, for the first time, treated the city as a “social laboratory”, immersing themselves in the daily lives of immigrant enclaves, slums, and high-crime areas, using participant observation to capture the hidden social structures within space. Their research proved for the first time that the spatial layout of a city is not naturally formed, but constantly reconstructed in the game between different groups, capital, and power. Space itself is a social product,承载着不平等、冲突与正义的可能 (carrying the possibilities of inequality, conflict, and justice). This is the core mark that distinguishes urban sociology from general sociology, and also the theoretical origin of all the analyses in this book.

一、芝加哥学派的实地观察：城市作为社会实验室 / 1.1 Chicago School's Field Observation: The City as a Social Laboratory

19世纪末的芝加哥，是资本主义快速工业化的典型样本。1890年芝加哥人口刚突破100万，到1920年已经飙升到270万，其中70%是来自东欧、南欧、中国的移民，剩下的30%是刚从南方迁移过来的非洲裔美国人。这座城市在30年里扩张了3倍，大量的移民挤在市中心没有自来水和下水道的棚屋里，而城市的边缘则是快速扩张的工厂区和铁路网，富人们住在芝加哥湖岸线的豪华别墅里，和移民社区仅隔几条街的距离。这种极端的空间隔离，为芝加哥学派的学者提供了最天然的研究场域。

Late 19th century Chicago was a typical sample of rapid capitalist industrialization. In 1890, Chicago’s population had just exceeded 1 million, and by 1920 it had soared to 2.7 million, 70% of whom were immigrants from Eastern Europe, Southern Europe and China, and the remaining 30% were African Americans who had just migrated from the South. The city expanded three times in 30 years, with a large number of immigrants crowded into shantytowns in the city center without running water and sewers, while the edge of the city was the rapidly expanding factory area and railway network. The rich lived in luxurious villas on the Chicago lakefront, only a few streets away from the immigrant enclaves. This extreme spatial segregation provided the most natural research field for Chicago School scholars.

帕克1914年到芝加哥大学社会学系任教之前，已经在底特律做了10年的记者，报道过工人运动、移民社区的黑帮冲突、市政腐败，这些经历让他坚信：社会学不能停留在抽象的 theorizing 里，必须到真实的城市空间里去观察普通人的生活。到芝加哥之后，他第一时间联系了简·亚当斯，亚当斯1889年在芝加哥第19区创办了 Hull House，是全美第一个移民社区服务中心，已经和当地的波兰、意大利、犹太移民打了20年的交道，帕克带着自己的学生住在 Hull House 的宿舍里，每天跟着亚当斯去移民家庭走访，去工厂采访工人，去帮派聚集的酒吧观察，收集了上万页的访谈记录和民族志资料。[^3]

Before joining the Department of Sociology at the University of Chicago in 1914, Park had worked as a reporter in Detroit for 10 years, covering labor movements, gang conflicts in immigrant enclaves, and municipal corruption. These experiences convinced him that sociology could not stay in abstract theorizing, but must go to real urban spaces to observe the lives of ordinary people. After arriving in Chicago, he immediately contacted Jane Addams, who founded Hull House in Chicago’s 19th Ward in 1889, the first immigrant community service center in the United States, and had worked with local Polish, Italian, and Jewish immigrants for 20 years. Park and his students lived in the dormitory of Hull House, following Addams every day to visit immigrant families, interview workers in factories, and observe in bars where gangs gathered, collecting tens of thousands of pages of interview records and ethnographic materials.[^3]

除了帕克，芝加哥学派的另一位核心人物厄尼斯特·伯吉斯，用的是另一种实地研究方法：他每天花3个小时坐有轨电车绕芝加哥转一圈，记录沿途的商业类型、住宅质量、人口构成、地价变化，连续做了5年，最后画出了著名的“芝加哥同心圆模型”。这个模型第一次把城市的空间结构和社会结构对应起来：中心的第一环是中心商务区（Central Business District, CBD），聚集了银行、百货公司、写字楼，地价最高；第二环是“过渡带”（Zone in Transition），就是原来的移民棚屋区，后来变成了贫民窟、工厂、仓库，地价最低，流动人口最多，犯罪率最高；第三环是工人住宅区，是第二代移民攒了钱之后搬离过渡带的居住区；第四环是中产阶级住宅区，是白领、小商人居住的地方；第五环是通勤带，是富人住的郊区，每天坐火车到市中心上班。[^4]

Another core figure of the Chicago School, Ernest Burgess, used another field research method: he spent 3 hours every day taking a streetcar around Chicago, recording the types of businesses, housing quality, population composition, and land price changes along the way, and did this continuously for 5 years, finally drawing the famous “Chicago Concentric Zone Model”. This model was the first to correspond the spatial structure of a city with its social structure: the first ring in the center is the Central Business District (CBD), where banks, department stores, and office buildings are concentrated, with the highest land price; the second ring is the “Zone in Transition”, which was originally the

il移棚屋区，后来变成了贫民窟、工厂、仓库，地价最低，流动人口最多，犯罪率最高；第三环是工人住宅区，是第二代移民攒了钱之后搬离过渡带的居住区；第四环是中产阶级住宅区，是白领、小商人居住的地方；第五环是通勤带，是富人住的郊区，每天坐火车到市中心上班。[^4]

The Zone in Transition, originally the immigrant shantytown area, later turned into slums, factories, and warehouses, with the lowest land prices, the largest floating population, and the highest crime rate. The third ring is the working-class residential area, where second-generation immigrants moved after saving money to leave the transition zone. The fourth ring is the middle-class residential area, where white-collar workers and small business owners live. The fifth ring is the commuter belt, where the wealthy live in the suburbs and commute to the city center for work every day.[^4]

为了验证这个模型的现实性，帕克和他的学生跟踪了127户1890年到1920年间抵达芝加哥的波兰移民家庭，记录了他们每一代的居住空间移动轨迹：第一代移民几乎全部集中在第二环的过渡带，平均居住时间8.2年，期间有23%的家庭因为失业、疾病、帮派冲突搬回老家，有17%的家庭因为犯罪被捕、被驱逐；第二代移民有62%搬到了第三环的工人住宅区，平均居住时间12.7年，犯罪率比第一代低41%；第三代移民有48%搬到了第四环的中产阶级区，职业以教师、护士、文员为主，犯罪率接近全市平均水平。[^5] 这个跟踪研究第一次用实证数据证明：城市的空间移动不是个体的随机选择，而是社会结构、经济机会、制度排斥共同作用的结果，空间分层和社会阶层分化是同步发生的。

To verify the realism of this model, Park and his students tracked 127 Polish immigrant families who arrived in Chicago between 1890 and 1920, recording the s
