Resource-based cities, which are widely distributed in China, contribute significantly to China's sustainable development. The digital economy and the construction of ecological civilization are central issues in the sustainable development of resource-based cities, and it is necessary to analyze the impact of the digital economy on the ecological resilience of resource-based cities. Thus, this paper measures ecological resilience of 117 resource-based cities from 2011 to 2020 using the entropy weight TOPSIS (technique for order preference by similarity to ideal solution; see Table 1 for a list of acronyms) method and empirically investigates the impact and mechanism of digital economy on ecological resilience using the spatial Durbin model (SDM) and intermediary effect model. The results show that the ecological resilience of resource-based cities has a certain upward trend, with a stepwise distribution pattern from east to west. There is a significant positive correlation between ecological resilience of resource-based cities, showing the phenomenon of club convergence which is primarily dominated by high-high (H-H) and low-low (L-L). The digital economy has a significant spatial spillover effect, which promotes ecological resilience of resource-based cities in the local and adjacent regions. A mechanism analysis reveals that technological innovation and industrial structure are mediators between digital economy and ecological resilience of resource-based cities, with significant heterogeneity in region and growth cycle. Among them, the intermediary role of technological innovation is stronger. Following the above findings, this paper proposes policy suggestions related to digital economy evolution and ecological resilience enhancement. This paper further enriches the literature on the ecological resilience and provides a theoretical basis for government policy-making.
资源型城市在中国分布广泛，对中国的可持续发展做出了重大贡献。数字经济和生态文明建设是资源型城市可持续发展的核心问题，有必要分析数字经济对资源型城市生态韧性的影响。因此，本文采用熵权TOPSIS法（逼近理想解排序法；首字母缩写列表见表1）测度了2011—2020年117个资源型城市的生态韧性，并运用空间杜宾模型（SDM）和中介效应模型实证研究了数字经济对生态韧性的影响及其作用机制。结果表明，资源型城市的生态韧性呈一定上升趋势，呈现出从东到西的阶梯状分布格局。资源型城市的生态韧性之间存在显著的正相关关系，呈现出以高高（H-H）和低低（L-L）为主导的俱乐部趋同现象。数字经济具有显著的空间溢出效应，促进了资源型城市本地及相邻地区的生态韧性。机制分析表明，技术创新和产业结构是数字经济与资源型城市生态韧性之间的中介变量，在区域和增长周期上存在显著的异质性。其中，技术创新的中介作用更强。基于上述研究结果，本文提出了与数字经济演进和生态韧性提升相关的政策建议。本文进一步丰富了生态韧性方面的文献，为政府决策提供了理论依据。
