Do the urban polycentricity and dispersion affect multisectoral carbon dioxide emissions? A case study of 95 cities in southeast China based on nighttime light data

open access: yesInternational Journal of Digital Earth, 2023
Effectively exploring the impacts of urban spatial structures on carbon dioxide emissions is important for achieving low-carbon goals. However, most previous studies have examined the impact of urban spatial structure on total carbon emissions based only

Spatial segregation and urban structure [PDF]

open access: yesJournal of Regional Science, 2019
AbstractIn this paper, we develop a model of spatial segregation mediated by competitive land prices. Agents of two groups consume city land and benefit from social interactions. Because of cultural or ethnic differences, intragroup interactions are more frequent than intergroup ones.

Spatial Mismatch, Search Effort and Urban Spatial Structure [PDF]

open access: yesSSRN Electronic Journal, 2003
Abstract The aim of this paper is to provide a new mechanism for the spatial mismatch hypothesis. Spatial mismatch can here be the result of optimizing behavior on the part of the labor market participants. In particular, the unemployed can choose low amounts of search and long-term unemployment if they reside far away from jobs.

Revealing intra-urban hierarchical spatial structure through representation learning by combining road network abstraction model and taxi trajectory data

open access: yesAnnals of GIS, 2023
The unprecedented urbanization in China has dramatically changed the urban spatial structure of cities. With the proliferation of individual-level geospatial big data, previous studies have widely used the network abstraction model to reveal the ...
