| 英文摘要 | Digitalization is transforming urban development by integrating emerging technologies into industrial upgrades, smart city initiatives, and climate monitoring. Digital technology, climate factors and urban form are intertwined in the development of cities, however, their complex interactions on PM2.5 pollution remain unclear. This study employs an optimal parameters geographical detector model to assess the impacts of digital technology, urban form, and climate factors on PM2.5 pollution, especially the interaction effects, using data from 272 Chinese cities across the years 2005, 2010, 2015, and 2020. The findings reveal that population density and secondary industry structure is the most significant socioeconomic factor. Digital technologies currently have relatively minor individual impact; while urban forms such as urban landscape complexity and fragmentation also affect PM2.5, with cities that have a unipolar center and complex shapes generating higher PM2.5. The individual effect of digital technology on PM2.5 pollution reveals an inverted U-shaped nonlinear relationship, initially promoting and then inhibiting pollution. However, when interacting with other factors, they can significantly exacerbate pollution. Interactions between digital technology and GDP, as well as with urban compactness, size and connectivity (PC1 and PC4), consistently demonstrate a nonlinear compound effect. Notably, the strength of these interactions between digital technology, climate factors, and urban form (PC1-PC4) tends to increase and then decrease over time. While the interaction between digital technology, climate factors, and urban form continues to exacerbate PM2.5 pollution at this stage, the ongoing advancement of digital technology, coupled with improved climate monitoring, pollution tracking, and optimized urban spatial planning, has the potential to mitigate PM2.5 in the future. This underscores the necessity of considering both individual factors and their intricate interactions with urban forms, socio-economic elements, and climate factors in developing comprehensive and effective policies to address PM2.5 pollution, especially in response to the emerging technologies. |
