The analysis of ‘polycentric urban regions’ (PURs) crucially depends on the operational definition of their constituent centres. We extend an insight into this issue by exploring how analyses of the level of intra- and inter-city polycentricity in the Yangtze River Delta, China, are contingent upon the identification and territorial delineation of its centres. The results help to specify more clearly PUR measurement procedures, and provide further evidence for the conceptual, analytical and empirical importance of consistent city definitions for regional studies in general and for research into urban and regional China in particular.

Urban parks are critical for sustainable urban development. They are of theoretical and practical significance for analyzing the visual landscape of recreational spaces from the perspective of the elderly. This analysis can be used for exploring new methods for optimizing recreational space layouts to improve the physical and mental health of the elderly in parks, thus realizing the sustainable development of urban society. Taking Ziyang Park in Shangrao Central District of Jiangxi Province, China, as an example, starting from the visual characteristics of the elderly, this study quantitatively calculated the landscape viewability, total view ratio, and water view ratio for the elderly in each recreational space using Python Scripting for ArcGIS. We briefly express the elderly suitability of the visual landscape for each recreational space through a weighted synthesis of the calculation results. Our findings show that, in Ziyang Park, the elderly suitability of the visual landscape for recreational spaces is not only low overall, but also gradually decreases from the interior to the exterior of this park. Moreover, this spatial distribution may be caused by the location of zoning, surface elevation, and road slopes, as well as the individual characteristics of each recreational space. Finally, we discuss the requirements of the elderly for some geographical factors, along with the feasibility of using ArcGIS 3-D analysis to optimize the layout of the park recreational space, with the aim of providing a new research perspective and an effective reference method for designing layouts of such spaces that are favorable for the elderly to better guarantee the sustainable development of urban society.

Although the literature often suggests that the economic prowess of ‘polycentric urban regions’ partly results from the ability of their constituent cities to promote functional spillovers through ‘borrowed size’, the empirical evidence remains scarce. This paper finds that polycentricity boosts the positive functional spillovers of producer service sector of city clusters beyond their boundaries only when city clusters have larger population and better urban infrastructure connectivity. And consequently, functional spillovers increase urban labour productivity. The labour division among cities could be the essential mechanism for the linkage between polycentricity and regional functional spillovers.

This study aimed to identify the non-linear association between population density and obesity in China and to provide empirical evidence for the public health orientated guideline of urban planning. By conducting a longitudinal study with data collected from the China Health and Nutrition Survey (CHNS) between 2004 and 2011, we applied fixed-effect models to assess the non-linear association between the compact built environment and waist–hip ratio (WHR), controlling for sex, age, nationality, education, employment status, marital status, household size, household income, and residents’ attitudes. Our findings reveal that the built environment is one of the key determinants of obesity. The U-shaped influence of population density on WHR was observed. Moreover, influence differs according to sex and weight status. Our findings indicate healthy city planning has the potential to improve the built environment to reduce obesity risk and promote public health.

City planners are increasingly drawn to the possibilities of transforming urban spatial structure as an important strategy for reducing air pollution. This paper addresses mixed findings in the existing literature through reliable methodology and heterogeneity tests. We examined the effects of spatial mono- and polycentricity on PM2.5 concentrations using spatial econometric models based on a three-year panel of data for cities at, or above, the prefecture in China. We found that population density had a robust moderating effect. That is, all else being equal, PM2.5 concentrations are lower when low-density cities have a strong-monocentric spatial structure and when high-density cities are polycentric. We estimated the population density threshold at which point the relationship between structure and density changes at about 160 persons/km.2 Our findings can serve as a possible criterion for differentiating low- and high-density cities in China and guide policymakers in planning optimal urban structures to mitigate air pollution.

Many studies have explored the relationship between population density and obesity, but there is no consensus, particularly in dense Chinese cities. This study applied gradient boosting decision trees to 2014 national survey data to examine the non-linear or threshold effects of population density at both local and regional levels on waist-hip ratio (WHR), controlling for other built environment elements and socio-demographics. Built environment elements collectively have a stronger predictive power than socio-demographics (56.6% vs. 43.4%). Within a certain range, regional population density is negatively associated with WHR, but its marginal effect diminishes beyond the upper threshold. Local population density has a U-shaped relationship with WHR. These results suggest that urban planners can alleviate the risk of obesity through population densification, but over-densification tends to be inefficient, and sometimes counterproductive.

The environmental sustainability of polycentric spatial structures in urban planning must be evaluated to ensure the sustainable development of city regions. Given the mixed conclusions of previous studies, as well as the lack of information on reliable methods of assessment and quantifiable mechanisms, a three-year dataset for prefecture-level and above city regions in China and spatial econometric models were used to examine the relationship between regional polycentricity and CO2 concentrations. After robust testing, we confirmed that polycentric structures decrease the mean CO2 concentrations of city regions, significantly reducing CO2 concentrations in primary city centers and mildly increasing those in city subcenters. Further quantitative analyses of the mechanisms underlying these patterns revealed that the CO2-reduction effect of polycentric structures is due to the balancing of reductions in commuting duration, transference of industrial CO2 to neighboring areas, and an increase in household CO2 emissions.

As an important subset of the urban population and a major contributor to urban social wealth, the elderly play an important role in a city’s sustainable development. Based on data from the statistical yearbook and an empirical investigation, this paper evaluated the elderly suitability of 75 parks in China’s Shanghai Central District using a self-defined Python script tool based on ArcGIS. According to spatial differences in the elderly suitability of parks, we employed spatial interpolation to explore the reasons for variations in park services in different residential spaces in Shanghai Central District. The results revealed the following: (1) the elderly suitability of parks in Shanghai Central District decreases gradually from the inner ring to the outer ring; (2) the park accessibility in Shanghai Central District is generally low, and the park service space can be divided into five categories ranging from “low accessibility, super-low elderly suitability” to “high accessibility, high elderly suitability”; and (3) the advantages of regional function and location, the development of regional culture and tourism economy, and the implementation of regional elderly-care policies are factors promoting the improvement of the elderly suitability of regional park services. Finally, this paper provided scientific decision-making suggestions for Shanghai and other aging cities to optimize the elderly suitability of urban parks.

Although polycentrism is widely regarded by city planners and policymakers as a potential solution for reducing regional disparities, there is currently little empirical basis for accepting or rejecting this claim. Our study aims to fill this empirical gap by providing reliable evidence as to whether or not a polycentric urban structure can reduce regional economic disparities. However, we reach a counter-intuitive result: monocentricity, from the morphological perspective, is robustly associated with less territorial economic disparity in China’s prefectural regions. Further analyses illustrate that the core cities in monocentric regions can share the benefits of agglomeration through labor mobility, and monocentricity does not introduce an extra agglomeration shadow. Meanwhile, cities within polycentric regions may not “borrow” as much function or performance from each other as expected. These results suggest that polycentric-oriented spatial strategy, at least in terms of morphology, may not be an appropriate policy to enhance cohesion in China.

Debates of polycentricity or dispersal concerning the locational patterns of decentralized employment have caused widespread concern owing to their differing social and economic consequences. However, studies relating to these debates do not account for the reasons for the inconsistencies. Based on available point employment data, this paper seeks to respond to the debates by documenting and explaining the spatial transformation of Shanghai at different geographic scales. We find that the period from 2004 to 2008 captures a trend of employment centralization. But a reverse trend of decentralization occurred between 2008 and 2013, which is characterized by general dispersal at a large scale, accompanied by polycentricity at a small scale. These results contribute to the literature by highlighting the role of scale effect in addressing the debates about polycentricity or dispersal and provide insights for identifying urban spatial structure in planning practice.

We examine the effects of the urban built environment on PM2.5 (fine particulate matter with diameters equal or smaller than 2.5 μm) concentrations by using an improved region-wide database, a spatial econometric model, and five built environment attributes: Density, design, diversity, distance to transit, and destination accessibility (the 5Ds). Our study uses Shanghai as a relevant case study and focuses on the role of density at the jiedao scale, the smallest administrative unit in China. The results suggest that population density is positively associated with PM2.5 concentrations, pointing to pollution centralization and congestion effects dominating the mitigating effects of mode-shifting associated with density. Other built environment variables, such as the proportion of road intersections, degree of mixed land use, and density of bus stops, are all positively associated with PM2.5 concentrations while distance to nearest primary or sub-center is negatively associated. Regional heterogeneity shows that suburban jiedao have lower PM2.5 concentrations when a subway station is present.

Using data on new private firm formation in prefectural cities in China in 2008 and internal migration of Chinese people in 2000, this paper examines to what extent cultural diversity can explain the regional variation of entrepreneurship. The results indicate that, holding other factors constant, cultural diversity vigorously promotes new private firm formation, especially in the manufacturing industry and for small firms. We address the endogeneity of cultural diversity by applying instrumental variables methods and confirm the relative robustness of this result.

This paper examines the effect of spatial structure, as measured on the monocentricity–polycentricity dimension, on labour productivity at the prefectural level in China. Using pooled cross-sectional and instrumental variable techniques, we find that, all else being equal, prefectures with a more monocentric spatial structure have a higher labour productivity, robust to different specifications. Furthermore, large agglomeration economies may fuel the beneficial effects of monocentricity. We conclude that, in terms of economic performance, monocentric-oriented spatial strategy could be a better choice for Chinese prefecture-scale regions.

Previous literature on the link between the built environment and body mass index (BMI) has paid very limited attention to the built environment at different geographical scales, the moderating effects of socioeconomic attributes, or developing countries, and has provided mixed evidence on some built-environment attributes. Thus, in this study, we explore the relationship between the built environment at both neighborhood and city scales and BMI, based on a sample of 4114 individuals from across China. Our findings show that (1) built-environment elements at both city and neighborhood scales are significant associated with BMI, although the city-scale built environment elements show more associations with BMI than the neighborhood scale; (2) the relationship between built-environment elements and BMI is moderated by individual socioeconomic attributes and behaviors; and (3) while at first, BMI decreases with increased city population density, it subsequently increases as density increases further. Thus, to prevent overweight and obesity, urban policymakers should consider the built environment at both neighborhood and city scales, give sufficient considerations to the heterogeneous effects of individual socioeconomic attributes and behaviors, highlight the reasonable size and density of cities and promote the jobs-housing balance.
