While the warming effect of urban expansion is well-documented, the thermal impact of various urban morphology changes remains less clear. Our study investigates the changes in land surface temperature (LST) associated with urbanization, utilizing Local Climate Zone (LCZ) time-series data and satellite-derived LST measurements from three major Chinese urban agglomerations. Time series analysis was applied to examine LST variations over the period from 2003 to 2020. Our research indicates that urban renewal, predominantly characterized by vertical development, exerts an asymmetric effect on urban temperatures: it mitigates urban warming during daytime (-0.13±0.067 °C(mean ± se)) but intensifies it at night (0.20±0.02 °C (mean ± se)). The effect of urban expansion on urban warming is markedly more pronounced during the day (0.55±0.041 °C (mean ± se)) than at night (0.20±0.015 °C (mean ± se)). At the city scale, changes in urban morphology generally contribute to a warming effect, both diurnally and nocturnally. Urban expansion is identified as the primary urban morphology change contributing to the rise in LST. However, the divergent impacts of vertical development, which is likely to account for a larger share of future urbanization, must not be underestimated.</div></div>","PeriodicalId":48659,"journal":{"name":"Sustainable Cities and Society","volume":"124 ","pages":"Article 106307"},"PeriodicalIF":10.5,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Digital technology innovations (DTI) have a dual impact on carbon emissions (CE), particularly amid the growing trend of networked urban agglomerations and the uncertain influence of geospatial spillovers. Based on the socio-economic data and remote sensing interpretation data of the urban agglomeration in the middle reaches of the Yangtze River (MRYRUA) from 2000 to 2020, this study portrays the manufacturing investment network of the urban agglomeration. It further examines the direct and spillover effects of DTI on CE within urban agglomeration, focusing on the manufacturing investment network and geospatial spillover perspectives. The results show that from 2000 to 2020, the investment in manufacturing in MRYRUA gradually shifted from intra-urban to inter-urban connections, with the proportion of inter-urban investment connections reaching 62.96% in 2020. DTI significantly suppresses CE, with a 0.182 percent reduction in CE for every 1% increase in DTI. From the perspective of geospatial spillovers, DTI significantly increases CE in neighboring regions. Similarly, from the manufacturing investment network perspective, it notably raises CE in the regions receiving investments. Under the geospatial and network externality frameworks, the direct emission reduction effects of DTI outweigh its spillover-driven emission increases by factors of 2.07 and 1.59 respectively, resulting in an aggregate net carbon reduction effect across the urban agglomeration. The direct and spatial spillover effects of DTI on CE exhibit heightened significance in small and medium-sized cities and the Changsha-Zhuzhou-Xiangtan Urban Agglomeration.</div></div>","PeriodicalId":48659,"journal":{"name":"Sustainable Cities and Society","volume":"124 ","pages":"Article 106321"},"PeriodicalIF":10.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
