The recent literature on the “consumer city” and the “love of variety” argues that the provision of urban amenities makes a city more attractive. Meanwhile, polycentric urban development has been highlighted by academics and policymakers as a sustainable urban development regime, although its purported benefits need to be further investigated. Against this background, this paper empirically examines the relationship between polycentricity and the provision of urban amenities in 309 Chinese cities. After controlling for the size, population density, wage, and human capital, this paper finds that a higher degree of intra-urban polycentricity is associated with a larger number of urban amenities. Additionally, when all the covariates above are held, a higher degree of intra-urban polycentricity is associated with a greater diversity of urban amenities. Robust checks show that these findings are consistent with different polycentricity indices and diversity measures. Finally, possible explanations of the relationship between intra-urban polycentricity and urban amenities are provided from both the producer and consumer perspectives.

During Afghanistan’s rapid urban growth, development diversified from state-run initiatives to ones led by local municipalities or nongovernmental entities such as private enterprises. Owing to these various efforts, cities face environmental challenges, squatter settlements, and unbalanced development. Responding to these interconnected challenges, cities need to increase their resilience to deal with the combined effects of urbanization, changing geopolitical contexts, and culture. In this study, we focused on dimensions of culturally responsive solutions for the built environment in Kabul, Afghanistan. Culture, as a key element in the concept of sustainable development, refers herein to the relationship between Afghan customs and belief systems as it influences and shapes the architecture of the urban environment. Initially, the study provides a conceptual understanding of sustainable urban development and the importance of culture. We have attempted to approach urban segregation in Kabul based on socioeconomic factors and address the essential role of culture in this unique context. Such segregation can be hazardous to both the current and future sustainability of urban development. To conclude, we provide in-depth insights into the contribution of culture and propose culture as a possible dimension of sustainability and an integral part of environmental, economic, and social dimensions of development.

With the rapid urbanization in China, the disasters and the problems related with the urban underground space (UUS) exploitation increase. As an inevitable choice for sustainable urban development, how to increase the efficiency of the underground space use and augment the resilience of the UUS are the main challenges today in China. In this study, the strategic demands of the sustainable urban development on the underground space exploitation in Chinese cities have been analyzed and discussed. The associated problems and difficulties on the underground space exploitation were discussed. Moreover, the possible solutions were also proposed.


Today, physical growth and spatial development without urban plans are inevitable due to population growth and increasing migration, which in some cities has caused the city sprawl and disrupt the city and degrade its environment. Therefore, it recognizes the spatial and physical development of the city as well as presents a pattern It is considered as one of the most important issues facing urban planners for the future of metropolitan cities, in order to guide it towards sustainable urban development. A model that identifies the directions of physical extension of the city, land use, physical form, and spatial distribution of activities in order to minimize damage to agricultural and environmental land around the city. Shiraz city has experienced five different structure along its life.the existence of different structures in Shiraz caused the observation of multiple patterns of development in it. Accordingly, the purpose of this research is to identify, analyze and organize the spatial development pattern of the city of Shiraz. The research methodology is applied based on its nature, descriptive-analytical, and in terms of its purpose. The data and information needed to conduct the research was collected through library studies and field operations, and then the obtained data were analyzed based on Shannon and Heldren entropy models. Surveying the results of this work shows that in the period of 1385-95, 59% of its growth has been due to population growth and the remaining 41%, due to horizontal and sprawl growth, which has resulted in decrease in grass population concentration and increase in gross capitation of town land. So, in order to prevent inefficient use of urban lands and reduce the costs of creating infrastructure and facilities and urban amenities and achieving sustainable urban development, the proposed model for physical development of the city of Shiraz is a compact city model, which, given the existing capacities and potentials, It can be used in the city.

Cycling is known to be environmentally friendly and beneficial to public health and sustainable urban development. Cycling has recently increased in Chinese cities as a result of the emergence of station-less bike-sharing systems. This study examines the emergence, rapid growth and consolidation of station-less bike-sharing systems and the role of suppliers, users and government regulators. It shows that these systems developed unevenly, growing most in large cities in eastern and south-eastern China, and explores the relationship between this spatial distribution and the nature of the service and the socio-economic characteristics of cities. To investigate patterns of, and reasons for, the use of these systems, this research also reports the results of a survey of users and non-users, identifying their gender, age, income characteristics and attitudes to station-less systems.

At present, rail transit in China is booming. At the same time, some big cities are undergoing a crucial stage of adjustment of urban spatial structure. Therefore, it is significant to study the relationship between the development of rail transit and the evolution of urban spatial structure. This paper reviews the development of Guangzhou rail transit and the evolution of Guangzhou urban spatial structure, and discusses the relationship between them. The conclusion is that there is interactive relationship between the development of rail transit and the evolution of urban spatial structure, and the construction and planning of rail transit should coordinate with the current condition and future planning of urban spatial structure. During network planning, the focus should not only be placed on the rail transit project itself, but the construction of a scientific and reasonable urban spatial structure, so that rail transit can contribute to sustainable urban development.
