【摘要】 数字经济正推动生产、生活和治理方式发生深刻变革，逐渐成为促进共同富裕的关键力量。基于2014—2023年我国30个省份（不包括西藏和港澳台）面板数据，使用动态多指标决策问题的投影寻踪模型（PP-IPM）测度共同富裕水平，并探究数字经济对共同富裕的影响效应和作用机制。研究发现：数字经济有助于促进共同富裕，该结论在经过一系列稳健性检验后依旧成立；数字经济对可持续度的促进作用最强，富裕度次之，对共享度的促进作用不明显；数字经济对共同富裕的促进作用呈现出边际递减的特征；数字经济对东、中、西部地区共同富裕的促进效应依次递减；数字经济通过提升新质生产力水平、推动区域协调发展和提高科技创新水平促进共同富裕。更多还原

【Abstract】 The digital economy drives profound changes in production, lifestyles and governance, serving as a key force for common prosperity. Using provincial panel data from 2014 to 2023 covering 30 Chinese provinces(excluding Tibet, Hong Kong,Macao, and Taiwan), this paper introduced a projection-pursuit-based ideal point model to measure the level of common prosperity,and explored the impact and mechanisms of the digital economy. The results indicated that the digital economy significantly promoted common prosperity, a conclusion remained valid after a series of robustness checks. Specifically, the effect of the digital economy was strongest on sustainability, followed by affluence, while its impact on sharing was not significant. The promoting effect exhibited a characteristic of diminishing marginal returns Regionally, the effect also decreased sequentially across the eastern, central, and western regions. Mechanism tests revealed three mediating mechanisms, including enhancing new quality productive forces, promoting coordinated regional development, and advancing scientific and technological innovation.更多还原
