| 英文摘要 | Food delivery services (FDS) are rapidly reshaping urban food environments, with contested impacts on spatial inequality. Here, we analyze walking-based versus delivery-based food service accessibility and spatial inequality across 43,504 neighbourhoods in 19 Chinese megacities (>10 M population), encompassing 430,600 service outlets. We find that while pronounced spatial clustering of service outlets drives significant baseline inequality, food delivery services substantially mitigate this disparity through three mechanisms: expanding service reach (55.91% coverage increase), vastly increasing choice (28.75-fold increase), and reducing spatial variation in access time (19.93% CV decrease). Critically, our cross-city comparative analysis reveals this equalizing effect is neither uniform nor universal, but exhibits strong scale-dependency and morphological contingency. Smaller cities (<1500 km(2)) achieve substantial Gini coefficient reductions of 45-53%, with FDS functioning as transformative spatial equalizers through a Hump Effect that maximally benefits suburban belts (10-20 km from centers). Conversely, larger megacities (>2000 km(2)) experience attenuated improvements of 13-21%, where FDS operate more as core optimizers reinforcing existing hierarchies. Socioeconomic stratification analysis reveals a dual equity structure: while 80.8% of lowest-income neighbourhoods show positive accessibility improvements, wealth-based disparities persist-particularly in large cities where the highest-income quintile achieves gains nearly three times greater than the lowest-income quintile. However, a compensatory floor effect emerges in smaller cities, where lower-income neighbourhoods attain accessibility improvements comparable to middle-income groups in larger cities. These findings challenge simplistic narratives of either technology-driven polarization or universal democratization, demonstrating that FDS impacts are conditional outcomes shaped by interactions between platform algorithms, urban morphology, and developmental stage. |
