基于高清卫星影像与多源动态数据,绘制高时空分辨率地块图斑一手数据库,量化解析2001—2020年间天津内城更新的行动路径及其社会影响逻辑。研究发现:转型期内城更新行动规模大、强度高、时空异质性显著,多发生于历史文化富集、空间肌理完整、区位优势突出的传统旧城和旧工业仓储区,并经由大规模拆除重建迅速引发用地功能格局的系统转型;同时,转型期内城更新分别在经济财富分配、社群空间迁移、日常生活转变三个维度引发复杂的次生社会影响,当前仍待持续开展精准施策、标本兼治的治理调控。研究补充了完整内城尺度下有关“存量更新社会绩效”的实证经验,有助于中国城市在新时期的精细化规划编制与更新治理。

Since China's reform and opening-up in 1978, stock land regeneration has played an increasingly important and unique role in the evolution process of China's urban space during the transition period. However, China's urban practice has long been closely bound to the theme of economic development, which makes the domestic research on China's urban regeneration process focus on its spatial and economic dimensions while relatively ignoring its social impact. Based on high-definition satellite images and other dynamic data, this paper draws 8998 pieces high resolution land plots, and analyzes the spatio-temporal path of Tianjin's inner-city regeneration actions from 2001 to 2020. The empirical research finds that urban regeneration actions mostly occur in traditional urban areas and old industrial storage areas with rich history and culture resources, complete spatial texture, as well as significant location advantages. At the same time, large-scale demolition and reconstruction quickly triggers a systematic transformation of the functional structure of urban land use. Complex historical backgrounds such as the land finance paradigm, socioeconomic transformation, and incremental planning inertia are the external driving factors for the formation of the above characteristics; at the same time, the practice of inner-city regeneration in China during the transition period also causes complex secondary social impacts at least in three dimensions. In the social-economic dimension, the real estate development process based on stock areas has achieved large-scale wealth redistribution among inner-city citizens. In the social-space dimension, material space regeneration has triggered an overall functional reorganization, which has driven the continued agglomeration and dispersal of diverse social groups in the city. In the social-life dimension, these short-term, concentrated, and semi-mandatory demolition and reconstruction actions in traditional urban areas have fundamentally reshaped the daily lives of residents who have migrated out of the old city center. Finally, as a prospect, we believe that this research may help improve the theoretical construction of the social impact assessment and social value cognition of China's contemporary urban regeneration actions, and support the high-quality spatial planning and governance in China's future stock-development era.
