Urban ecological environment resilience is an important characteristic that should be possessed in the process of urban development. It is conducive to coping with the challenges of multiple risks and disturbances such as climate change, resolving chronic pressure, improving the ability to resist disaster risk, self-adjustment, and recovery, to maintain the structure and function stability of the urban system. The digital economy is a new economic form caused by the new technological revolution, which may effectively promote economic ecology and ecological economization. We clarify the elements of the digital economic system, construct the coupling evaluation index system of "digital infrastructure-industrial digitization-digital industrialization," and establish the coupling degree model to analyze the characteristics of the integration interaction, coordination, and self-organization of the digital economy subsystem. Based on emergency management theory, adaptive management concept, and resilient city theory, an evaluation index system is constructed from four levels of prevention, resistance, adaptation, and recovery to measure urban ecological resilience. Taking 278 cities in China from 2011 to 2021 as the research object, we established a spatial econometric model to explore the dynamic mechanism of digital economy system composition and coupling coordination to enhance urban resilience and summarize the theoretical model form. Based on this, we further propose countermeasures and suggestions for improving urban ecological resilience by using a digital economic system.
城市生态环境韧性是城市发展过程中应具备的重要特征。它有利于应对气候变化、解决慢性压力、提高灾害风险抵御能力、自我调整和恢复等多种风险和干扰的挑战，维持城市系统的结构和功能稳定性。数字经济是新科技革命带来的新经济形式，可能有效促进经济生态化和生态经济化。我们厘清数字经济系统的要素，构建“数字基础设施-产业数字化-数字产业化”的耦合评价指标体系，并建立耦合度模型，分析数字经济子系统的融合互动、协调和自组织特征。基于应急管理理论、自适应管理理念和韧性城市理论，从预防、抵抗、适应和恢复四个层面构建城市生态韧性的评价指标体系。以 2011-2021 年中国 278 个城市为研究对象，建立空间计量经济模型，探讨数字经济系统构成与耦合协调对提升城市韧性的动态作用机制，总结理论模型形式。在此基础上，进一步提出利用数字经济系统提升城市生态韧性的对策建议。
