It is important to explore an urban smart development path which unites smart growth with driving shrinkage perfectly in forming scientific and sustainable development concept and responding to new normal strategic opportunities. Based on statistic data of 294 prefecture-level cities and above in China from 2000 to 2015, we analyzed spatial and temporal evolution of urban smart development in China by constructing a dynamic fitting model of urban land expansion, population growth, and economic development as well as the coefficient of variation of urban smart development(CVSD). Further efforts were then made to consider differential distribution regularity of urban smart development so as to understand the driving mechanisms of heterogeneous classification of urban smart development in China from different scales and scale variation. Our results indicate that: 1) the disordered growth tendency of urban cities in China is overall well controlled in the middle, and late research and it mainly presented a doublet coexistence of shrinkage disordered cities and smart developing cities. It is particularly obvious that Northeast China and East China have regarded shrinkage disordered cities and smart developing cities as main development tendency separately. 2) Areas with basic stability and relative variation were relatively dispersed across the time period, but the proportion was far beyond areas with significant variation. It demonstrates a relative equilibrium spatial and temporal differential evolution pattern of prefecture-level cities and above in China, except for Tongling, Lanzhou and Chaoyang. 3) prefecture-level cities and above in China are mostly characterized by shrinkage disordered and smart development classification under the background of different scale and scale variation from 2000–2015; however, the spatial resonance relation is not obvious. 4) There are many interaction factors forming an important driving mechanism in developing the spatial and temporal pattern of urban smart development in China, including natural geographical factors, industrial structure adjustment, human capital radiation, regional traffic accessibility, and government decision-making intervention.展开更多

Essentially an integrated eco-industrial park, these clusters demonstrate applications of industrial ecology principles among the occupant units, besides promoting sustainable societies from economic, environmental and social perspectives. The holistic planning and development of these clusters from economic, environmental and social sustainability considerations or alternatively, the sustainability assessment of these clusters is highly complex. The research reported upon forms part of a larger study that aims to develop an integrated decision support system for sustainability assessment of inclusive smart innovation cluster. The paper discusses the conceptual model of the cluster and the need to establish context specific key indicators and influence factors from economic, environmental and social sustainability considerations. The paper proposes a structured methodology for development of key indicators and influence factors. The paper concludes by identifying a set of 184 key indicators and influence factors for comprehensive sustainability assessment of inclusive smart innovation cluster.展开更多

The results show that： （1） three main categories of smart low-carbon cities are found; namely, leaders with high SLSQ, steady ones with av- erage SLSQ and lagging ones with low SLSQ; （2） the SLSQ level shows a spatial change trend of diminishing from the southeast to the northwest and differing within regions; （3） the SLSQ level indicates an urban scale change trend of decreasing from the big to the small and differing within each scale; （4） the SLSQ level suggests an ad- ministrative hierarchy change trend of descending from the high to the low and differing within each class; （5） based on the SLSQ, three dynamic patterns were identified： leading mode, steady mode and preparing mode, among which the steady mode accounts for the vast majority of smart low-carbon development in major Chinese cities.展开更多
