摘要
COVID-19 给人们的日常生活带来了巨大的破坏,加速了城市数字化转型,并推动了社会空间发展的可持续改善。分析技术的出现激发了整合社会空间关系的可能性,需要新的城市研究方法和评估系统,而近期的研究很少讨论这些问题。为了弥补这一研究空白,本研究提出了一个测量框架,将基于位置的社交网络服务(LBSN)和 POI 数据结合起来,以测试城市更新项目的有效性。具体来说,本研究通过客观地利用基于位置的社交网络服务与社交媒体(微博签到和大众点评数据)和 POI 数据,量化城市活力,以评估人们的偏好和地点设置的整合。本研究以中国苏州 2019 年至 2021 年的 153 个更新项目为研究对象,将城市更新项目分为四种类型:(1)社区;(2)商业;(3)公共空间;(4)工业。此外,还采用二元逻辑回归模型分析了不同再生措施对城市空间活力的影响。研究结果表明,将 LBSNs 数据与 POI 数据相结合,可以通过时空分析有效评估城市活力的转变。研究结果表明,商业和社区更新项目对城市活力有明显影响,而与文化相关的改造措施对提高城市活力至关重要。系统化的城市更新测量框架可以提高城市更新效率,促进决策合理化,为理解复杂的社会空间关系、确保城市可持续发展提供依据。
Toward effective urban regeneration post-COVID-19: Urban vitality assessment to evaluate people preferences and place settings integrating LBSNs and POI
COVID-19 brought tremendous disruption to daily life, accelerated urban digital transformation, and prompted sustainable improvement in socio-spatial development. The emergence of analytic technologies stimulates possibilities for integrating socio-spatial relationships, and new urban research methods and assessment systems are required, which are rarely discussed in recent studies. To bridge the research gap, this study proposes a measurement framework that combines Location Based Social Networking Services (LBSNs) and POI data to test the effectiveness of urban regeneration projects. Specifically, the study quantifies urban vitality to evaluate people’s preferences and place settings integrating by objectively utilizing LBSNs with social media (Weibo check-in and Dianping data) and POI data. This study focuses on 153 regeneration projects in Suzhou, China, from 2019 to 2021 and categorizes urban regeneration projects into four types: (1) community, (2) commercial, (3) public space, and (4) industry. Further, a binary logistic regression model was conducted to analyze the effects of different regeneration measures on urban spatial vitality. The research findings show that combining LBSNs data with POI data can effectively assess the transformation in urban vitality with spatiotemporal analysis. The results indicate that commercial and community regeneration projects significantly impacted urban vitality, and cultural-related renovation measures are critical in improving urban vitality. The systematic urban regeneration measurement framework could promote the regeneration efficiency and rationalization of decision-making, providing a basis for understanding complex socio-spatial relationships and ensuring sustainable urban developmeng sustainable urban development significantly.
