The big data revolution is heralding an era where instrumentation, datafication, and computation are increasingly pervading the very fabric of cities. Big data technologies have become essential to the functioning of cities. Consequently, urban processes and practices are becoming highly responsive to a form of data-driven urbanism that is the key mode of production for smart cities. Such form is increasingly being directed towards tackling the challenges of sustainability in the light of the escalating urbanization trend. This paper investigates how the emerging data-driven smart city is being practiced and justified in terms of the development and implementation of its innovative applied solutions for sustainability. To illuminate this new urban phenomenon, a descriptive case study is adopted as a qualitative research methodology to examine and compare London and Barcelona as the leading data-driven smart cities in Europe. This study shows that these cities have a high level of the development of applied data-driven technologies, but they slightly differ in the level of the implementation of such technologies in different city systems and domains with respect to sustainability areas. They also moderately differ in the degree of their readiness as to the availability and development level of the competences and infrastructure needed to generate, transmit, process, and analyze large masses of data to extract useful knowledge for enhanced decision making and deep insights pertaining to urban operational functioning, management, and planning in relation to sustainability. London takes the lead as regards the ICT infrastructure and data sources, whereas Barcelona has the best practices in the data-oriented competences, notably horizontal information platforms, operations centers, dashboards, training programs and educational institutes, innovation labs, research centers, and strategic planning offices. This research enhances the scholarly community’s current understanding of the new phenomenon of the data-driven city with respect to the untapped synergic potential of the integration of smart urbanism and sustainable urbanism for advancing sustainability in the light of the emerging paradigm of big data computing. No previous work has, to the best of our knowledge, explored and highlighted the link between the data-driven smart solutions and the sustainable development strategies in the context of data-driven sustainable smart cities as a new paradigm of urbanism.

新兴的数据驱动型智慧城市及其创新的可持续性应用解决方案：伦敦和巴塞罗那的案例

大数据革命预示着一个时代，仪器仪表，数据化和计算正日益渗透到城市的整个结构中。大数据技术已成为城市运转必不可少的要素。因此，城市流程和实践正在对一种以数据为驱动的城市主义形式作出高度反应，这是智能城市的关键生产方式。鉴于不断升级的城市化趋势，这种形式正越来越多地致力于应对可持续性的挑战。本文研究了如何通过可持续发展的创新应用解决方案的开发和实施来实践和证明新兴的数据驱动型智慧城市。为了阐明这种新的城市现象，采用描述性案例研究作为定性研究方法，以检查和比较伦敦和巴塞罗那作为欧洲领先的数据驱动型智能城市。这项研究表明，这些城市在应用数据驱动技术方面的发展水平很高，但是在可持续性领域方面，它们在不同城市系统和领域中实施这些技术的程度略有不同。在准备，程度，生成和传输大量数据，传输，处理和分析大量数据以提取有用的知识以增强决策能力以及与城市有关的深刻见解所需的能力和基础设施方面，他们的准备程度也略有不同与可持续性相关的运营功能，管理和计划。伦敦在ICT基础设施和数据源方面处于领先地位，而巴塞罗那在面向数据的能力方面拥有最佳实践，特别是水平信息平台，运营中心，仪表板，培训计划和教育机构，创新实验室，研究中心和战略规划办公室。这项研究增强了学术界对数据驱动型城市的新现象的当前理解，并结合了智能城市主义和可持续城市主义的融合在挖掘大数据计算范式方面的潜力，以提高可持续性。据我们所知，以前的工作都没有
