本文的核心目标是对城市流动人口的社区融合机制进行深度剖析。以往实证研究强调，外来人口借由获取相对优势的社会经济地位，从而较好地适应城市生活，这一思路显然是以“结构逻辑”为基础的社会融合观。本文认为，包括身份认同在内的外来人口社会融合问题，实际上与他们在城市社区的日常生活密切相关，因故提出基于社会交往和社区参与的“互动逻辑”，聚焦于个体原有的社会关系与在本地建立的人际交往共同建构其社区成员身份的过程。更进一步，笔者试图引入地区宏观经济变量，将流动人口的社区融合问题重新置于社会变迁的背景之下加以讨论，建立探讨该问题更为综合的多层分析模型。 本研究样本数据来源于清华大学中国城镇化与劳动移民研究调查，主要有以下几点重要的发现：首先，乡—城流动人口和城—城流动人口在社会地位、受教育水平、经济收入和社会生活等多个方面正在逐渐趋同，特别是80后、90后的新一代劳动移民群体；其次，社会互动能很好地解释流动人口的社区融合差异，引入相关变量后，模型拟合优度显著提高。其中，与邻里和亲属密切的互动能显著提升个体融入社区的概率，而同乡间的亲密度则产生显著的负效应。笔者将其归因为，与同质化的群体密切互动，不利于适应所在地的主流文化和价值观，而社会网络具有的规范性反而在强化其对原有社群的认同；其三，社会互动的融合效应在乡—城流动和城—城流动两类群体之间存在显著差异。研究发现，较高频率的邻里互动对农业户籍人口有显著正效应，而亲属互动显著提高城—城流动人口的社区融入，同乡关系对两类群体都有显著的负效应。这种流动人口来源的城乡差异并不是基于资源禀赋而产生的，而是根源于传统乡村和现代城市本身在文化和价值观的不同，进而影响两类人的感知图示；最后，加入城市经济增速、经济规模和工业化速率等宏观解释变量，本文发现第二产业增速对流动人口社区融合有显著负效应。而在经济快速增长的地区，同乡亲密度的离心力被削弱。 本研究的理论意义主要有两点：一是呈现社区融合的互动逻辑，不再以纯粹的资源匹配思路来理解这一问题，呈现日常化的融合机制；二是将城市宏观经济变量引入到对流动人口社区融合的讨论中，建立解读该问题的多层模型。但笔者必须强调，由于宏观结构对微观个体的影响是一个宏大的理论框架，本研究的发现更多是一种探索性的思考和一种可能性的解释，需要后续的实证研究进一步加以论证。

This dissertation deeply investigates the issues of the mechanism of migrants’ community integration in urban China by examining how personal social interaction and macroscopic changes take effects on an individual’s recognition of identity in the unfamiliar social environment. The concept, the interactive logics, is offered to contradict with the structural logics, which is overemphasized by the informed researches, to shed light on migrants’ regular and daily life in the urban areas. Using data from the Survey on Urbanization and Migrant Workers in China, which is collected by Tsinghua University, the author concludes in four parts. 1) At the aspects of social status, years of schooling, earnings and patterns of social life, the gap between the rural-to-urban migrants and the urban-to-urban ones is narrowed down; 2) The effect of social interaction on migrants’ community integration is reported to be significant. The migrants with more interaction with relatives are more possible to identify themselves as the real members in the place of residence. By contrast, the intimate relationship with the people from the same native place produces a centrifugal force; 3) Mechanism of integration into the community differs between rural-to-urban migrants and urban-to-urban ones, which is attributed to the distinctive ways of perception. 4) The growth rate of GDP per capita and the added-value the secondary industry, presenting the macro-economic change, are testified to be significant. In the urban areas with more rapid economic growth, the market logic reconstructs migrants’ definition of the relationship with people from the same native place and therefore decrease the centrifugal force. The theoretical significances of this dissertation lie on that it offers a different research perspective on social integration and bring the macroscopic factors back. By postulating that migrants are the ones with more complicated social relations, the author attempts to give a vivid description on their daily life instead of on the rigid structure matching process.
