As a key measure to realize Chinese-style modernization, the construction of new urbanization injects vitality into China 's urban economic growth by building modern industrial system, and it is also great significance improve resilience. This study examines data from 278 Chinese cities spanning period 2006-2022, utilizing multi-period Difference-in-Differences model moderating effect investigate impact on cities' The findings indicate that adoption significantly enhances Notably, when examined perspectives geographical location, scale, agglomeration, development level, particularly pronounced in eastern region, small cities, non-urban agglomeration with lower levels development. mechanism test demonstrates affects resilience fostering technological innovation upgrading structure. Essentially, restructuring serve as intermediaries fortifying through implementation urbanization. result, recommendations are formulated bolster economies.

ABSTRACT This study evaluates the impact of climate and land use changes on Lake Tana Basin's hydrology, using datasets use, weather patterns, topography, soil characteristics, discharge. Future data were obtained from Global Climate Models (GCMs) Coupled Model Intercomparison Project Phase Five (CMIP5) generated Weather Generator (LARS-WG) tool Long Ashton Research Station with five distinct GCMs. Land projected Markov chain model based cellular automata (CA). The Soil Water Assessment Tool (SWAT) was used to assess in hydrological elements between reference future periods, calibration validation ensured by Integrated Parameter Estimation Uncertainty Analysis (IPEAT). Projections indicate a 4.9 °C increase ensemble mean annual temperature 16% rise precipitation end 21st century under Representative Concentration Pathway (RCP) 8.5. Additionally, average components, including water yield, water, percolation, lateral flow, runoff, actual potential evapotranspiration, are expected due combined changes. Therefore, it is crucial fully understand these cumulative impacts before formulating implementing resource management strategies basin.

Cities encounter increasing risks and challenges under new development patterns, digital economy (DE) can drive cities’ improved resilience to natural social uncertainties. Based on data collected the Yangtze River Economic Belt from 2011 2021, situation of regional DE urban (UR) was measured, impact mechanisms UR were analysed theoretically empirically using a benchmark regression model. The findings are as follows: test revealed that contributed significantly in region. mediating effect through two pathways: industrial structure upgradation energy restructuring. moderating suggested environmental pollutant emissions had negative between DE, structure, effects UR, whereas CO2 positive structure. Heterogeneity analysis indicated positively except upstream region, where coefficient insignificant. Overall, this study highlights crucial role improving elucidates theoretical pollution control carbon reduction measures UR.
