大都市商业绅士化空间格局、形成机理与规划响应研究——以南京为例

绅士化已成为遍及全球的社会空间重构现象，而商业演替与空间重构驱动的商业绅士化则是当前大都市的突出特征。相比居住绅士化，商业绅士化具有更丰富的城市转型发展内涵和更广泛积极的效应。但受研究数据、方法及视角局限，当前研究仍滞后且脱离于实践。本课题以区域中心城市南京为例，采用多源数据和GIS空间分析方法探索商业绅士化空间精准识别的技术路线，并总结其空间格局及演变过程。其次，融合供给端与需求端的多元推动主体、作用方式及其影响因素，揭示商业绅士化形成与演变的复杂机理，归纳商业绅士化的主要模式。最后，基于对商业绅士化趋势的预判，从“主动商业绅士化”和“缓和商业绅士化”有机结合的角度，探讨大城市功能提升、产业结构优化和空间重构的规划响应策略。以期拓展国内绅士化研究的深度和广度，同时为新形势下我国大城市高质量发展，培育和建设国际消费中心提供参考。

As a phenomenon of social spatial reconstruction, gentrification has taken place all over the world, while commercial gentrification driven by commercial succession and spatial reconstruction has become a prominent feature of current metropolis.Compared with residential gentrification, commercial gentrification has richer connotation in urban transformation and development, and leads to more positive effects. However, due to the limitations of research data, methods and perspectives, current research is still lagging behind and divorced from practices. Taking the regional central city Nanjing, China as an example, this paper adopts multi-source data and some GIS spatial analysis methods to explore the approaches that can be used to identify of commercial gentrification space accurately, and then summarizes its spatial pattern and evolution process. Secondly, it integrates the multiple driving actors, their diverse action and influencing factors of the supply side and the demand side, and to reveals the complex mechanism of the formation of commercial gentrification. It also summarizes the main modes of commercial gentrification. Finally, after predicting of the trend of commercial gentrification in Chinese metropolises, this paper discusses how to response to commercial gentrification through function up-gradation, industrial structure optimization and spatial reconstruction, from the perspective of combining "promoting commercial gentrification" and "moderating commercial gentrification" together. This research is expected to enrich the research on gentrification in China, and provide reference for the high-quality development of China's big cities，as well as how to build international consumption centers under the new situation.
