【摘要】 夜间经济的快速发展显著影响了夜间时段居民在城市空间中的行为，但夜间经济与城市活力的定量研究成果十分有限。本次研究基于南京市主城区空间数据、两个周末夜间定位数据和POI数据，构建了以400m方格网为空间单元、两小时为时间单元的基础数据库，通过核密度分析法分析南京主城区夜间城市活力的空间分布特征，并结合时空地理加权回归模型，探讨了城市活力与夜间经济的时空关系。结果表明，城市活力在时空维度上的波动受到夜间经济多种业态的非均质影响。研究成果以期为城市夜间经济规划和空间规划提供参考借鉴。更多还原

【Abstract】 The rapid development of the night-time economy has significantly affected the activities of residents in urban space during the night-time hours. Based on the main urban area of Nanjing spatial data, two weekends night location data, and POI data, this research constructed the primary database with a 400m grid as the space unit and 2 hours as the time unit, and examined the spatial distribution characteristics of urban vitality in the main urban area of Nanjing at night through kernel density analysis and combined with a geographically and temporally weighted regression model to explore the spatio-temporal relationship between urban vitality and night-time economy. The findings show that fluctuations in urban vitality in the spatio-temporal dimension are affected by the non-homogeneity of multiple sectors of the night-time economy.更多还原
