Understanding its spatiotemporal evolution and associated factors can support evidence-based urban governance and differentiated policy design. This study investigates the spatiotemporal heterogeneity, regional disparities, spatial transitions, and driving mechanisms of CDWGE across China from 2005 to 2023. A super-efficient SBM-DDF model is first employed to measure CDWGE, followed by the Dagum Gini coefficient and its decomposition, kernel density estimation, spatial Markov chains, and the geographical detector model to reveal its dynamic evolution and influencing factors. The results show that China’s overall CDWGE improved during the study period, suggesting progress in construction and demolition waste management performance and resource efficiency. However, regional growth rates varied considerably, following the pattern of central &gt; western &gt; northeast &gt; eastern, indicating differentiated pathways toward sustainable construction and demolition waste management. At the provincial level, CDWGE displayed a relatively balanced but clustered spatial distribution, with evidence of club convergence. Regional disparities widened over time, with transvariation density contributing most to the overall inequality. The spatial Markov results further reveal path dependence and neighbourhood effects, suggesting that provincial CDWGE transitions are associated not only with local conditions but also with the states of neighbouring regions. Among the driving factors, technological innovation shows the strongest explanatory power for the spatial differentiation of CDWGE, while factor interactions mainly exhibit two-factor enhancement and nonlinear enhancement effects. These findings contribute to sustainable cities research by providing a spatial decision-support framework for identifying priority regions, strengthening interregional collaboration, and designing differentiated policies to advance the achievement of zero-waste cities and circular urban development in developing countries.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"19 4","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149034956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing the Fairlie non-linear decomposition method, we examine migrants with varied socioeconomic characteristics and migration patterns to identify the factors associated with homeownership rates. Results show that the homeownership rates among migrants in their destination cities more than doubled during this period, increasing from 8.97% to 19.41%. Higher household income and education, longer residence, family-oriented migration, willingness to integrate, nonagricultural <i>hukou</i>, and public sector employment are positively associated with homeownership, while migrants in provincial capitals or municipalities are less likely to own housing. Decomposition results further indicate that family-oriented, long-term migration, and improvements in migrants’ socioeconomic status make the largest contributions, highlighting the growing importance of mobility transition.

This study develops a national network stress test for Yemen using OpenStreetMap road extract and WorldPop constrained population surface. Demand is represented by 8,460 population-weighted grid cells covering 41.18 million people and linked to mapped markets, health facilities, and fuel stations. The study then evaluates five stylized closure mechanisms at 1%, 5%, 10%, and 20% of simplified physical road links, including random removal, spatially clustered removal, major-road targeting, access-betweenness targeting, and exact-bridge targeting. At 1% random removal, the mean newly disconnected population share across services is 1.12%, indicating a shallow low-intensity response. The most disruptive mechanism depends on closure intensity. Exact bridges produce the largest disconnection at 1% closure (15.65% across services), access-betweenness targeting at 5% (35.28%), and major-road targeting at 10% and 20% (49.65% and 65.04%). Among people who remain connected, rerouting is highest under major-road targeting at 1% and 5%. At higher intensities, connected-only delay becomes non-monotonic because disconnected users no longer remain in that distribution. Spatial closures look modest in national averages but impose severe local losses. At 1% closure, 2.01% of the national population is newly disconnected, compared with 59.64% of the population within 25 km of the closure center and 93.95% within the realized closure footprint. These findings show that national averages should be complemented by local exposure measures when assessing road-network vulnerability and prioritizing access-sensitive recovery.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"19 4","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12061-026-10012-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, this study refines the concept of “rural lifestyle mobilities”—the evolving spatio-temporal organization of daily activities in relation to livelihood change—and operationalizes it through a multidimensional accessibility framework. Drawing on survey data from 2,437 households across three counties of the Jianghan Plain, China, we use an observed-variable serial multiple-mediation path analysis implemented in a structural equation model (SEM) to examine whether livelihood capital and livelihood transition are statistically associated with household-level mobility changes and whether the proposed indirect pathways are consistent with the data. Results reveal that housing and consumption have larger average mobility change scores than working and leisure, reflecting a consumption-oriented transition in rural daily life. Livelihood capital has the most consistently positive estimated association with mobility outcomes, whereas livelihood transition shows domain-specific and, in some cases, opposing-sign indirect paths. Because the data are retrospective and observational, these estimates are interpreted as model-based associations rather than causally identified effects. By integrating temporal dimensions into the analysis of rural lifestyle mobilities, this study advances applied spatial research on rural transitions and provides policy-relevant evidence for improving everyday accessibility and living conditions in rapidly urbanizing regions.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"19 4","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During China’s feudal period, with the help of convenient canal transport, a “North-South dual-core” urban system formed in China’s Grand Canal, with several “single-center” or “multicenter” urban systems in its subregions. In the 20th century, especially since railway construction in mainland China, the continuous decline in inland river canal transport led to major changes in the urban system but left its main core cities basically unchanged. In the 21st century, the excavation of historical and cultural value has once again revitalized some cities that once flourished along China’s Grand Canal. However, affected by the rapid development of modern transportation, these cities have not recovered their former regional status.

Using data from the Russian Fertility and Mortality Database (2015–2022) covering 83 regions, we analyzed cause-specific infant mortality via multivariable negative binomial regressions, with the infant population applied as an offset term. In the primary analysis, models were adjusted for infant sex and place of residence (urban vs. rural) to capture group-specific risks. To evaluate the systemic robustness of deprivation effects against latent geographic processes and healthcare supply, a separate sensitivity analysis was performed on the total population without sex and residence stratification, integrating spatial eigenvector filtering and pediatrician density. In the baseline models adjusted for infant sex and place of residence, mortality rates from poisonings, injuries, and external causes escalated progressively alongside gradient increases in economic deprivation. These findings remained robust and unchanged upon the further integration of spatial eigenvectors and pediatrician density into the regression frameworks. Additionally, the primary stratified analysis revealed significantly elevated infant mortality from neoplasms specifically within environmentally deprived rural pockets. However, in the unstratified sensitivity framework, this highly localized rural hazard signal disappeared due to a classic signal dilution effect caused by aggregating data across the total regional population without urban-rural segmentation.

Waterlogging probability maps for 2015 and 2025 were generated using a random forest model. Spatial relationships were assessed via the spatial mismatch index, bivariate LISA, colocation analysis, and the Gumbel copula for upper-tail dependence.

Colocation analysis further reveals that emergency shelters exhibit stronger spatial overlap with high-income core areas than with low-income peripheral areas, creating a paradox: the high-income group is colocated with both higher waterlogging risk and better risk-mitigation facilities, such as emergency shelters, suggesting that such facilities may be capitalized into housing prices to a greater extent than flood risk, while the low-income group faces neither.These findings highlight the complexity of environmental risk justice in megacities.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"19 3","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
