Effective evaluation on the coordination between socio-economy (V) and carbon emission (W) is essential for sustainable urban planning, and this study introduces an improved coupling coordination degree (CCD) model for conducting such evaluation. The limitation of the traditional CCD model has been examined. The effectiveness of the improved CCD model is demonstrated with its application in 30 case provinces of China by using the data collected for the period 1995–2015. The results show that: (1) The subjectivity embodied in the traditional CCD model in analyzing the coordination between V and W significantly distorts the true coordination between the two systems. (2) The improved CCD model is effective as its application can reflect the reality of the sample cases. (3) The average coordination degrees of the 30 case provinces for the surveyed period show an upward evolution, and the coordination statuses of these provinces have been transforming from low-grade symbiosis to high-grade symbiosis. (4) The spatial distribution of coupling coordination degree in China is characterized by a higher degree of coordination in the Eastern provinces. The results of applying the improved coupling coordination degree model can help decision makers formulate effective sustainable measures to balance socio-economic development with carbon emission reduction.

Abstract: In recent years, there has been rapid urbanization worldwide, resulting in both benefits and problems. Sustainable urbanization has become an important aspect in promoting sustainable development. Existing studies have introduced various methodologies to guide urbanization towards sustainable practices. The application of these methods has contributed to improving urban sustainability. To further support the effective applications of the principles of sustainable urbanization, a tool is needed to evaluate whether a particular process of urbanization is sustainable. In this paper, we introduce an alternative model for evaluating sustainable urbanization by investigating the relationship between urbanization and urban sustainability. The practice of sustainable urbanization is defined as a dynamic process that enables urban sustainability to improve or to maintain a certain level of practice. By employing this definition, we introduce a sustainable urbanization elasticity coefficient eSU , which is defined by two parameters: urbanization velocity (VμR ) and urban sustainability velocity (VμS ). The sustainability of an urbanization process is measured by the value of eSU or read from the VμR –VμS coordinate. A case study demonstrates the application of the measure eSU and the VμR –VμS coordinate. The proposed model is an effective tool to help policy makers understand whether the urbanization processes they support are sustainable and thus whether to correct practices. The model also allows comparison of different urbanization practices and thereby encourages the sharing of successful experiences. [Copyright &y& Elsevier]

Attempts for implementing sustainable urbanization have been reported and documented around the world. These efforts have led to a vast number of exemplary sustainable urbanization practices, classified as best practices. Best practices contain valuable information in the form of experiences, and learning from them represents an opportunity to replicate successful practices in other cities. This study collected and analyzed 185 best practices in sustainable urbanization from around the world. The main areas of action, the key methods adopted and the outcomes achieved by these practices were identified. Key elements in successful sustainable urbanization strategies were found by conducting a series of association analyses between the areas of action, methods and outcomes. Findings highlight the importance of community participation, capacity building, education, partnerships and job creation in achieving urban sustainability. [ABSTRACT FROM AUTHOR]

There is a large amount of population moved from countryside to cities in China during its urbanization in the past two decades. The majority of these people have no formal qualifications for city residency, and they are so-called ‘floating population’. The increase of this group of people has induced the pressure of land use in cities, and the contradiction between the demand and the supply of urban land has been intensifying particularly in those developed regions in China. This paper examines the impacts of floating population on urban land by presenting the interrelations between floating population and urban land expansion from the perspective of production land and living land. Structural equation model (SEM) is employed in conducting the analysis. The result shows that the floating population alone does not have direct effect on urban land expansion, but have indirect impacts through engaging in the production or living process. It is particularly interesting that floating people's living conditions have no direct positive effect on the increase of construction land. Based on the research results, suggestions are offered for improvements in government policy towards a more sustainable and integrated urbanization, including the provision of housing support, the formation of more urbanized society and sustainable development.
