数字经济网络构建为全国统一大市场建设注入了新动能，已成为畅通国内经济循环的关键支撑。利用2011—2020年城市层面数据，基于网络度中心度的研究视角系统考察城市在数字经济网络中的位置特征对其区域市场潜力的影响，结果表明，提升城市数字经济网络的度中心度对区域市场潜力具有显著促进作用，该结论在经过一系列稳健性检验后依然成立。这一促进作用主要通过强化市场一体化效应与技术溢出效应来实现。同时，该效应在地域分布与城市类型间并未呈现显著的梯度差异，表现出较强的普适性特征。基于研究结论提出对策建议，以期为优化城市网络位势、协同释放国内市场潜力以及加快数字强国建设提供有益的政策启示。

The construction of digital economy networks has injected new momentum into the development of a unified national market and has become a critical foundation for smoothing domestic economic circulation. Using city-level data from 2011-2020，from the perspective of network centrality， this study systematically examines how a city’s position within the digital economy network influences its regional market potential. The results show that enhancing a city’s degree centrality in the digital economy network significantly boosts its regional market potential， a finding that remains robust after a series of robustness tests. This effect is primarily driven by the strengthening of market integration and technology spillover effects. Moreover， the facilitating effect exhibits no significant gradient differences across geographical regions or city types， indicating strong generalizability. Based on these findings， policy recommendations are proposed to optimize urban network positioning， jointly unlock domestic market potential， and accelerate the construction of a leading digital nation.
