Eal the characteristics of the spatial structure of Chinese megacities at unique scales, such as static urban morphology and dynamic functional linkages. Prior research on Chinese cities mainly rely on demographic information to detect urban spatial structure at a single spatial scale. This can’t take into account the impact of employment around the formation of the spatial structure and lacks the commuting connections between property and workplaces. Moreover, the results of urban research are also dependent around the spatial scale, but small investigation has examined spatial structure at several scales. Hence, we employed jobs ousing massive data obtained from Baidu, which can simultaneously reflect a large-scale spatial distribution of employment and population, at the same time as the commuting flows connecting them. Apart from, we examined the traits of urban spatial structure at each macro-scale and meso-scale. Spatial autocorrelation in addition to a geographically weighted regression (GWR) model have been used to determine static polycentricity, and neighborhood detection was applied to recognize dynamic commuting communities. We found that: (1) the static traits in the spatial structure of megacities presented the coexistence of polycentricity in addition to a higher degree of dispersion at macro- and meso-scales; (two) the dynamic qualities of the spatial structure of megacities revealed two kinds of commuting communities at macro- and meso-scales, and most commuting communities had a good jobs ousing balance. This study tends to make up for the limitation of lack of an employment distribution viewpoint and dynamic functional connections in earlier analysis. The multi-scale evaluation outcomes also contribute to help urban managers and planners formulate relevant policies for spatial distribution optimization of urban functions and transportation improvement at distinctive spatial levels. The rest of this paper is organized as follows. Section 2 briefly critiques the literature connected to this study. Section three introduces the study region, data and solutions. Section 4 presents the research results. Section five discusses our findings. Section 6 concludes and discusses the prospective Bomedemstat Formula policy implications. two. Literature Assessment two.1. Sustainable Urban Improvement and Spatial Structure The concentrate on sustainable improvement concerns originated within the Brundtland C2 Ceramide Metabolic Enzyme/Protease Commission report in 1987. This notion is defined as development that may meet the requires from the present without the need of compromising the capability to meet these of your future generations [11]. The connotation of sustainable improvement is multidimensional, and its 3 pillars are environmental, social and economic sustainability [12]. In the point of view of sustainable development, cities, as buyers of energy and producers of waste, are regarded as practical places that trigger unsustainable challenges [13]. Thus, in the face of swelling urban populations, promoting the sustainable development of substantial urban locations is the important to attaining the global sustainable development targets [14]. In reality, the Planet Commission on Atmosphere and Improvement (WCED) emphasized the challenges of sustainable urban improvement when the notion was 1st proposed [11]. In current years, the subject of sustainable urban development has changed from no matter if the city can recognize sustainability to how the city can realize sustainable improvement [15,16]. For the design and style of sustainable cities, scholars have proposed a range of sustainable urbanism models, such as co.
