Modern cities currently face numerous challenges related to mobility, waste management, access to resources, etc. Smart Cities integrate information and communication technologies (ICT) to develop innovative solutions that can solve such challenges and create a higher quality of life for their citizens. Two elements need to be considered for smart cities to be successful. First, citizens must participate in the design of the smart city to take advantage of their ideas so that the smart city answers their real needs. Secondly, each city has its own unique characteristics that need to be considered to design a citizen participation strategy truly tailored and adapted to their respective context. In line with these two considerations, the goal of this paper is to identify the context factors that impact citizen participation strategies in smart cities. In order to reach that goal, we performed a qualitative case study of two cities that strive to be smart: Namur (Belgium) and Linköping (Sweden). This analysis allows us to understand how participation is implemented in two different cases and to infer the context factors that impact the respective strategies. Five context-factors have been identified in this study: the smart city consideration, the drivers for participation, the degree of centralization, the legal requirements, and the citizens’ characteristics. By identifying these factors, we can derive context-dependent recommendations about citizen participation for smart cities. These recommendations are then applied to the case of Brussels in Belgium. 相似文献

Smart cities are developing at increasing speed. Smart cities rely on the deployment of information and communication technology (ICT) that is digitally transforming our habitats. Digital transformation affects several areas from transportation, energy, government to the environment. But, primarily, it affects citizens. Therefore, the adoption of all areas of the smart city holds great research potential. The purpose of this paper is thus to provide an insight into millennials’ adoption of autonomous vehicles (AV), which are at the forefront of future transport. Millennials are an important focus group for smart city concepts since they are keen to adopt technology and new transport modes. Our research focuses on technology adoption, perception of the benefits, security, safety, mobility-related efficiencies and concerns as the key AV adoption factors. The impact of these factors is empirically tested with structural equation modelling using data from 382 millennials. We confirm the perceived benefits of AV are vital factors for AV adoption whereas the perceived safety of AV significantly reduces the influence of various concerns regarding AV. 相似文献

The expansion of big data and the evolution of Internet of Things (IoT) technologies have played an important role in the feasibility of smart city initiatives. Big data offer the potential for cities to obtain valuable insights from a large amount of data collected through various sources, and the IoT allows the integration of sensors, radio-frequency identification, and Bluetooth in the real-world environment using highly networked services. The combination of the IoT and big data is an unexplored research area that has brought new and interesting challenges for achieving the goal of future smart cities. These new challenges focus primarily on problems related to business and technology that enable cities to actualize the vision, principles, and requirements of the applications of smart cities by realizing the main smart environment characteristics. In this paper, we describe the state-of-the-art communication technologies and smart-based applications used within the context of smart cities. The visions of big data analytics to support smart cities are discussed by focusing on how big data can fundamentally change urban populations at different levels. Moreover, a future business model of big data for smart cities is proposed, and the business and technological research challenges are identified. This study can serve as a benchmark for researchers and industries for the future progress and development of smart cities in the context of big data. 相似文献

There is a growing body of literature calling for work on the emerging role of smart cities as information hubs and knowledge repositories. This article reviews the existing smart city literature and integrates knowledge management perspectives to provide an overview of future research directions. By demonstrating the multi-stakeholder relationships involved in smart city development, it takes a crucial step towards looking into the role of knowledge management in future smart city research. Eighty-two peer-reviewed publications were analyzed covering smart city studies in various research domains. The systematic review identifies five different themes: strategy and vision, frameworks, enablers and inhibitors, citizen participation, and benefits. These themes form the basis for developing a future research agenda focused on knowledge sharing and co-learning among cities via three research directions: socio-technical approaches, knowledge sharing perspectives and organizational learning capabilities. The paper also proposes a series of knowledge-driven policy recommendations to contribute towards the UN Sustainable Development Goals. 相似文献

Energy efficiency of public sector is an important issue in the context of smart cities due to the fact that buildings are the largest energy consumers, especially public buildings such as educational, health, government and other public institutions that have a large usage frequency. However, recent developments of machine learning within Big Data environment have not been exploited enough in this domain. This paper aims to answer the question of how to incorporate Big Data platform and machine learning into an intelligent system for managing energy efficiency of public sector as a substantial part of the smart city concept. Deep neural networks, Rpart regression tree and Random forest with variable reduction procedures were used to create prediction models of specific energy consumption of Croatian public sector buildings. The most accurate model was produced by Random forest method, and a comparison of important predictors extracted by all three methods has been conducted. The models could be implemented in the suggested intelligent system named MERIDA which integrates Big Data collection and predictive models of energy consumption for each energy source in public buildings, and enables their synergy into a managing platform for improving energy efficiency of the public sector within Big Data environment. The paper also discusses technological requirements for developing such a platform that could be used by public administration to plan reconstruction measures of public buildings, to reduce energy consumption and cost, as well as to connect such smart public buildings as part of smart cities. Such digital transformation of energy management can increase energy efficiency of public administration, its higher quality of service and healthier environment. 相似文献

智慧城市是经济高质量发展的产物,智慧城市建设离不开城市中创新型企业的发展。以智慧城市第一批、第二批及第三批试点为自然实验,采用多点DID法检验智慧城市试点对企业创新的影响,并从政府补助、税收优惠等方面研究智慧城市影响企业创新的渠道。结果发现,智慧城市试点具有创新溢出效应,当城市被认定为智慧城市试点后,注册地企业的创新水平会显著提升。提升的渠道是：智慧城市试点之后,城市加大了政府补助、税收优惠等财政支持力度,这将正向促进企业创新。异质性检验发现,相对于高融资约束企业、国有企业,低融资约束企业、民营企业更能利用智慧城市创新溢出效应驱动自身创新;相对于低市场竞争环境、非制造业行业,高市场竞争环境、制造业企业更能利用智慧城市创新溢出效应驱动自身创新。 相似文献
