作为增加就业、提振消费及带动区域发展的城市消费"新蓝海",夜间经济在"后疫情时代"逐渐成为研究热点."夜间经济集聚中心"是夜间经济发展的核心和基础,国内外鲜有研究,它作为社会经济要素,具有非均匀对称和"灰色聚集"的特点,因此无法简单套用传统地理集聚中心的识别方法.研究从夜间经济的集聚机理出发,基于"点—轴系统"理论,提出了一种夜间经济集聚中心的识别提取方法,并利用广义对称图谱解构上海市中心城区夜间经济集聚中心的空间格局及其分异机理.首次为快速准确地识别夜间经济集聚中心,科学地挖掘其空间分布特点提供了系统的方法参考,为推动夜间经济的繁荣和可持续发展提供了决策支持.结果显示:在上海市中心城区范围内,共提取了 12个一级夜间经济集聚中心,26个二级夜间经济集聚区,夜间经济平均活力值分别为0.49和0.24.研究表明:①该方法能快速识别和提取夜间经济集聚中心.②上海夜间经济集聚中心呈"中心—外围"空间分布格局,交通导向性强;③基础设施完善程度和距市中心距离,是上海夜间经济空间集聚分异的主要驱动因子.④集聚中心的"色对称"空间格局,表明上海夜经济处于一种合理、可持续的发展阶段;未来规划中,可沿地铁二号线东西扩展并内部填充,亦可将集聚对称中心连接线作为发展轴,以"集聚区"的形式提升夜经济集聚效应.
Identification Method and Spatial Differentiation Mechanism of Shanghai Nighttime Economic Agglomeration Center from the"Generalized Symmetry Structure"Perspective
As a"New Blue Ocean"for urban consumption to increase employment,boost consumption and drive regional development,the night economy has gradually become a research hotspot in the"Post-Pandemic era".The"nighttime economic agglomeration center"is the core and foundation of the nighttime economic develop-ment,and there is no systematic studies available at home and abroad.As a social economic element,it has the characteristics of non-uniform symmetry and"grey clustering",so it cannot simply apply the traditional geo-graphical clustering center identification method.Based on the theory of"point-axis system",this paper propos-es a method to identify and extract the nighttime economic agglomeration centers,and uses the Geo-informa-tion Tupu of generalized symmetric to deconstruct the spatial pattern and differentiation mechanism of the night-time economic agglomeration centers in downtown Shanghai.For the first time,this paper provides a systemat-ic method reference for rapidly and accurately identifying the nighttime economic agglomeration centers and sci-entifically exploring their spatial distribution characteristics,and provides decision support for promoting the prosperity and sustainable development of nighttime economy.The results show that:within the central city of Shanghai,a total of 12 first-class nighttime economic agglomeration centers and 26 second-class nighttime eco-nomic agglomerations were extracted,and the average vitality values of the night-time economy were:0.49 and 0.24,respectively.Conclusions(1)The method proposed in this paper can quickly identify and extract night-time economic agglomeration centers;(2)The Shanghai nighttime economic agglomeration centers present a"center-periphery"spatial distribution pattern,forming a distinct hierarchical system;(3)The degree of infra-structure perfection and the distance from the city center are the main driving factors for the differentiation of Shanghai nighttime economic agglomeration;(4)The"Color Symmetry"distribution spatial pattern of the ag-glomeration center indicates that the night economy of Shanghai in a reasonable and sustainable development stage.In the future planning,it can be expanded and filled internally along Metro Line 2.The central connecting line of the agglomeration symmetry can also be used as the development axis to upgrade the nighttime economic agglomeration effect in the form of"Agglomeration Area".
