数字化发展是现代化人民城市建设的重要引擎，但其在赋能城市转型与升级的过程中，仍受区域协同不足、数据流通不畅、场景应用不深等多重约束制约。融合现代化与人民性理念，构建数字民生基础力、数字服务运行力、数字韧性保障力三维指标体系，以2011—2022年中国283个城市为研究样本，运用全局趋势面分析、空间自相关分析、标准化椭圆分析等方法，系统刻画城市数字化发展的时空分异特征。研究表明：我国城市数字化发展水平逐年提升但增速波动，规模扩张模式面临瓶颈；空间格局上呈现点状突破—带状延伸—片状拓展—网络互联的扩散路径，但边缘区域承载与连接薄弱；空间梯度上呈现协同驱动的发展格局，结构重心上移且中高位段稳步扩容；空间方向上呈现东西集聚深化、南北协同补位的趋势。为优化现代化人民城市的数字化发展时空格局，需要通过技术创新与场景融合、集群协同网络构建、全域格局统筹加以系统推进。

Digital development serves as a crucial engine of building modern cities of the people. However, its empowerment urban transformation and upgrading was constrained by multifaceted challenges, including insufficient regional synergy, obstructed data circulation, and superficial application of digital scenarios. Integrating the principles of modernization and people-oriented development, the study constructed a three-dimensional indicator system encompassing digital livelihood foundational capacity, digital service operational capacity, and digital resilience safeguarding capacity. Using a research sample of 283 Chinese cities from 2011 to 2022, and employing analytical methods such as global trend surface analysis, spatial autocorrelation analysis, and standardized ellipse analysis, the spatiotemporal differentiation characteristics of urban digital development were systematically examined. The findings revealed that: China's urban digital development level had demonstrated a year-on-year upward trend, albeit with fluctuating growth rates, while the scale expansion model had approached bottlenecks; spatially, the pattern had exhibited a diffusion trajectory from punctiform breakthroughs to belt-like extensions, followed by patchy expansions and ultimately networked interconnectivity, yet peripheral regions had remained weak in terms of carrying capacity and connectivity; across spatial gradients, a synergistically driven development pattern had emerged, with the structural gravity center shifting upward and the midto-high-level segments steadily expanding; directionally, the spatial dynamics had presented a trend of deepening east-west agglomeration and north-south collaborative complementarity. To optimize the spatiotemporal pattern of digital development in modern cities of the people, systematic advancements were required through technological innovation and scenario integration, construction of clustered synergy networks, and comprehensive coordination of the holistic spatial pattern.
