| 中文摘要:基于2003—2019 年长江中游城市群面板数据，采用双向固定效应模型、中介效应模型和空间杜宾模型探讨数字经济对产业融合发展的作用机制与影响。研究表明：数字经济对产业融合发展具有显著正向效应，且具有较强的异质性表现，在经济发达城市表现更为突出。在数字经济促进产业融合发展的过程中，市场需求、人口质量和创新活力的中介效应依次提高；数字经济对长江中游城市群产业融合发展存在显著的负向空间溢出效应。为此，应提升数字经济水平、优化城市资源配给、促进空间协调发展以达到数字经济和产业融合发展的良性互动。 |

| Has the Digital Economy Boosted the Convergence Development of Industries?—Taking the Urban Agglomeration in the Middle Reaches of the Yangtze River as an Example |

| Abstract:Based on panel data from the Urban Agglomeration in the Middle Reaches of the Yangtze River spanning from 2003 to 2019, this study explores the mechanisms and impacts of the digital economy on the development of industrial convergence using a two-way fixed effects model, a mediating effects model, and a spatial Durbin model. The results indicate that the digital economy has a significant positive effect on the development of industrial convergence, exhibiting strong heterogeneity, particularly in economically developed cities. Throughout the process of promoting industrial convergence through the digital economy, the mediating effects of market demand, population quality, and innovation vitality are sequentially enhanced. Additionally, there is a significant negative spatial spillover effect of the digital economy on the development of industrial convergence within the Urban Agglomeration in the Middle Reaches of the Yangtze River. Therefore, it is necessary to improve the level of the digital economy, optimize the allocation of urban resources, and promote coordinated spatial development to achieve a positive interaction between the digital economy and industrial convergence. |
