摘要
共同富裕是中国特色社会主义的本质要求。从“富裕程度”和“共享程度”两个维度构建评价指标体系，运用熵权TOPSIS法和地理信息系统等方法，对2011-2021年珠三角城市群9个地级市共同富裕水平的时空演变特征进行分析。研究发现：（1）整体上，珠三角城市群共同富裕水平整体呈现波动上升态势，各市的发展仍存在一定的差距；共同富裕水平综合指数从0.346升至0.618，呈现高速增长、波动调整和转型分化的三个阶段特征；（2）空间上，珠三角城市群共同富裕水平整体呈现出“深圳、广州、珠海占主导优势且发散，周边其他地区落后且紧凑”的态势。

Abstract
Achieving common prosperity for all citizens represents an essential requirement of Chinese-style modernization. This study developed a dual-dimensional evaluation framework from "affluence level" (economic capacity) and "sharing degree" (equitable distribution) to quantify common prosperity across nine cities in China's Pearl River Delta (PRD) urban agglomeration from 2011 to 2021. Utilizing the entropy-weighted TOPSIS integrated with GIS, we revealed critical spatiotemporal patterns:(1) The level of common prosperity in the PRD had shown a fluctuating upward trend, and there were still certain gaps in the development of each city. The comprehensive index of common prosperity had increased from 0.346 to 0.618, showing the characteristics of three stages: highspeed growth, fluctuating adjustment, and transformation and differentiation. (2) Spatially, the level of common prosperity in the PRD presented a situation where "Shenzhen, Guangzhou, and Zhuhai dominate and diverge, while other surrounding areas were backward and compact".
Key words： Common prosperity; Spatiotemporal disparities; Entropy-weighted TOPSIS; Pearl River Delta (PRD)
