Digital financial inclusion and common prosperity are pivotal elements in promoting the sustainable socioeconomic development of China. This study introduces a novel Multi-Criteria Decision Analysis (MCDA) method to evaluate Common Prosperity Index (CPI). Using this index, alongside Financial Inclusion (DFII) released by Peking University, it examines evolution coupling coordination relationship between digital within Yangtze River Delta (YRD) urban agglomeration from 2011 2021. By integrating gravity models social network analysis, paper, we thoroughly investigate spatiotemporal characteristics spatial relationship. The results indicate that both DFII CPI generally exhibit an upward trend, but decline degree reflects weakened interaction strength them. Specifically, Anhui significantly lags behind Jiangsu, Zhejiang, Shanghai prosperity, indicating regional imbalances. Furthermore, connections city has increased, with Nanjing’s siphon effect on cities becoming markedly stronger, number core increasing, which demonstrates geographical proximity feature development. Additionally, overall transitioning towards higher density “small-world” properties, suggesting trend toward stabilization. disparity centrality among decreased, enhancement centrality, where spillover effects areas such as Hangzhou-Ningbo, Nanjing-Changzhou, Shanghai-Suzhou-Wuxi promote peripheral cities. Based these findings, paper proposes policy recommendations for YRD region.
