进入“后单位时代”，原本均质的单位社区空间出现“杂化”，呈现出“绅士化”与“边缘化”两种截然不同的社会空间变化。本研究基于比较视角，采用多源数据，以武汉市中心城区为例，对单位社区绅士化与边缘化的过程、机制与响应展开研究。研究对单位社区绅士化与边缘化的特征进行界定，建立指标体系，开展空间精细化识别，判断研究区域单位社区绅士化与边缘化格局；结合典型社区案例，同时在城市与社区尺度下考察单位社区绅士化与边缘化的动态演变，并进行比较；基于资本与制度视角，探讨其形成机制与影响因素，重点分析物质资本、人力资本、社会资本及制度惯性对单位社区多样化演化路径的影响；基于线上舆情与线下访谈考察绅士化、边缘化下单位社区治理特点，与商品房社区比较，提出针对性响应策略。理论上，研究扩展了中国城市社会空间转型的分析框架，为绅士化、边缘化国际比较提供了新样本；实践上，为单位社区更新、现代化治理提供了理论与实践依据。

In the post-Danwei era, the originally homogeneous Danwei community space began to hybridize, showing two distinct trends in social space, namely gentrification and marginalization. Taking the central urban area of Wuhan as the study area, this study conducts a research on the process, mechanism and governance of the gentrification and marginalization in Danwei communities from a comparative perspective and by multi-source data. The study first defines the characteristics of the gentrification and marginalization in Danwei communities. Then, the spatial identification indicators are established to accurately distinguish the Danwei communities with gentrification and marginalization trends in the central urban area of Wuhan. Next, combined with typical case studies, the study examines the dynamic evolution process of the gentrification and marginalization in the Danwei communities at the city and community scale based on comparisons. After that, the study discusses the formation mechanism of the gentrification and marginalization in Danwei communities from the ‘capital’ and ‘institution’ perspectives, focusing on the impact of physical capital, human capital and social capital on the diversified evolution paths in the post-Danwei era. On this basis, the study continues to examine the governance characteristics of Danwei communities with gentrification and marginalization trends through the online public opinion and offline interviews, and compares them with general commercial housing communities. At last, a targeted strategy for Danwei community governance is proposed. Theoretically, this study expands the analytical framework for the social space restructuring in urban China and provides a unique Chinese sample for the international gentrification and marginalization comparison. In practice, the study offers theoretical and practical basis for Danwei community renewals and modern governance in the post-Danwei era.
