When cities develop rapidly, there are negative effects such as population expansion, traffic congestion, resource shortages, and pollution. It has become essential to explore new types of urban development patterns, and thus, the concept of the “smart city” has emerged. The purpose of this paper is to investigate the links between smart city policies and urban green total factor productivity (GTFP) in the context of China. Based on panel data of 200 cities in China from 2007–2016 and treating smart city policy as a quasi-natural experiment, the paper uses a difference-in-differences propensity score matching (PSM-DID) approach to prevent selection bias. The results show: (a) Smart city policies can significantly increase urban GTFP by 16% to 18%; (b) the larger the city, the stronger and more significant this promotion.

With the supply of water, energy and food facing severe challenges, there has been an increased recognition of the importance of studying the regional water–energy–food nexus. In this paper, Inner Mongolia, including 12 cities in China, was selected as a research case. A super-efficiency slack based measure (SBM) model that considered the undesirable outputs was adopted to calculate the regional total factor productivity (TFP) and the Malmquist–Luenberger index was used to investigate the change trend of the TFP from 2007 to 2016 based on understanding the water–energy–food nexus. Finally, influential factors of the TFP were explored by Tobit regression. The results show that the 12 Inner Mongolia cities are divided into higher, moderate and lower efficiency zones. The higher efficiency zone includes Ordos, Hohhot, Xing’an, and Tongliao, and the lower efficiency zone includes Chifeng, Xilin Gol, Baynnur, Wuhai and Alxa. There is a serious difference in TFP between Inner Mongolia cities. During the study period, the TFP of the water–energy–food nexus in Inner Mongolia cities shows a rising trend, which is mainly driven by the growth of technical progress change. However, the average ML values of the lower and moderate efficiency zones were inferior to the higher efficiency zone in six of the ten years, so the difference between Inner Mongolia cities is growing. According to the Tobit regression, the mechanization level and degree of opening up have positive effects on the TFP, while enterprise scale and the output of the third industry have negative effects on the TFP. Government support does not have any significant impact on the TFP. Finally, suggestions were put forward to improve the TFP of the water–energy–food nexus in Inner Mongolia cities.

This study explores the effect of land finance (LF) and producer services on green total factor productivity (GTFP) according to spatial and agglomeration economic theories. Then, based on the spatial Durbin model, we employ panel data of 283 Chinese cities at the prefecture level and above from 2003 to 2015 to estimate the effect of LF and producer services agglomeration on GTFP. We find that specialized agglomeration of producer services promotes the GTFP of the city and its neighboring cities. While diversified agglomeration is advantageous to the GTFP in the city, it significantly reduces in neighboring cities. LF not only improves the GTFP of the city and neighboring cities but also weakens the promotion effect of the specialized agglomeration of producer services on the GTFP of the city and surrounding cities. Furthermore, we find that there exists industry and regional heterogeneities of the effect.

The concept of Smart City (SC) has been popular recently, and has been adopted by many cities in the world with various implementation and development. As the world most population now concentrates on urban area, a sustainable city planning and management become important. As the population keeps growing,pressure and tension on a city arise: space for living, waste management, traffic congestion, sufficient clean water resources, and other issues. Beginning in around 2009, the concept of SC was designed to solve problems related to city growth in a sustainable manner. By using technology, Internet of Things (IoT), and community participation, SC aims to make the city a livable place for its inhabitants, putting people as the center of interest and in quality of life in sustainable manners as ultimate goal. This paper aimed to deliver a study on the trend of SC adopted by two cities: Amsterdam and Jakarta. The study was conducted through literature review. The data were analyzed to compare the concept of SC in each city from different parameters, focusing on the developmentprocess, technological adoption, political and institutional arrangement and implementation. The results show that each city has specif ic strategy to implement SC, based on their economic, social, environment and demographic characteristics. It is also important to underline that the main concept of SC is to attract related stakeholders in taking charge of their roles for the success of SC. Furthermore, both cities has a sharing vision in putting environment as the main framework of the development of SC.

Severe traffic congestion is ubiquitous in large urban centers. This paper provides the first causal estimate of the relationship between traffic density and speed and optimal congestion charges using real-time fine-scale traffic data in Beijing. The identification relies on plausibly exogenous variation in traffic density induced by Beijing’s driving restriction policy. Optimal congestion charges range from 5 to 39 cents per km depending on time and location. Road pricing would increase traffic speed by 11 percent within the city center and lead to an annual welfare gain of ¥1.5 billion from reduced congestion and revenue of ¥10.5 billion.

AbstractSmart city-policy makers and technology vendors are increasingly stating they want to bring about citizen-centered smart cities. Yet, it often remains unclear what exactly that means, and how citizens are envisaged as actors in smart cities. This article wants to contribute to this discussion by exploring the relation between smart cities and citizenship. It aims to do this by introducing a heuristic scheme that brings out the implied notions of citizenship in three distinct sets of smart city visions and practices: The Control Room envisages the city as a collection of infrastructures and services; The Creative City views the city from the perspective of (economic) geography and ponders on local and regional systems of innovation; The Smart Citizens discourse addresses the city as a political and civic community. These smart city discourses are mapped against two visions on citizenship and governance taken from political philosophy. A `republican' perspective with strong presence in social-democratic countries is contrasted with a libertarian one, most prominent in Silicon Valley approaches to smart city technologies. This provides a scheme to reflect on potential benefits and downsides if a specific smart city discourse would develop. Instances of smart cities may promote notions of citizenship that are based on consumer choice and individual responsibility, alternatively they could also reinforce collective responsibilities towards the common good of society.

Abstract. As current cities are attributed to particular dynamism consists of population density and increased urbanization, urban areas are facing some challenges for city logistics, both in terms of economic, environmental, and social impact. Especially, the debates over last-mile logistics are arising with inefficiencies in delivery cost (half truckload on delivery) and delivery time per parcel (unnecessary waiting-load periods at multiple stops) while inner-urban areas are especially suffered from traffic congestion, emission, and noise pollution. In this regard, smart cities as a concept with the potential to produce sustainable solutions to urban problems bring along with the need for innovative urban logistics systems to make conventional distribution channels of the city up to date. The key objective tackled in this paper can be defined as the identification of the city logistics schemes with highlighting current approaches in smart cities. The study adopts a systemic approach based on the typology of consolidation-distribution schemes in city logistics to define the feasibility of micro logistics initiatives from the scope of the smart city consisting of mobility, sustainability, and liveability. Thanks to a detailed examination of city logistics dynamics, this study can contribute theoretically to smart city logistics literature as well as practically the logistics sector.
