On the basis of importance that China attaches to the construction of ecological civilization and green development， this study analyzes the impact of digital economy development on ecological resilience by using the panel data of 286 cities at the prefecture level and above in China from 2011 to 2022. The results showed that the development of the digital economy could significantly improve the ecological resilience， and this result still held after a series of robustness tests. Furthermore， the enhancement effect of digital economy development on ecological resilience had a non-linear feature of marginal increase. In terms of its mechanism， the development of digital economy could improve ecological resilience by promoting technological innovation and economic agglomeration， and the government's increased attention to new quality productivity has strengthened the role of digital economy development in improving ecological resilience. Further study found that the development of the digital economy could improve the ecological resilience of the city， which had a significant spatial spillover feature， that is， the development of the digital economy could not only improve the ecological resilience of the city but also help to improve the ecological resilience of neighboring cities. The heterogeneity test showed that the enhancement effect of digital economy development on ecological resilience was due to the heterogeneity of urban geographic location， administrative level， and resource endowment， that is， compared with that in eastern， central， and resource-based cities， digital economy development in central and western， peripheral， and non-resource-based cities had a greater enhancement effect on ecological resilience. The conclusions of the study can provide useful inspiration for China to clarify the mechanism of improving ecological resilience and provide policy basis for regional cooperation to strengthen ecological resilience.
基于中国对生态文明建设和绿色发展的重视，本研究利用2011—2022年中国286个地级及以上城市的面板数据，分析了数字经济发展对生态韧性的影响。结果表明，数字经济发展能够显著提升生态韧性，且经过一系列稳健性检验后该结果依然成立。此外，数字经济发展对生态韧性的增强效应具有边际递增的非线性特征。从作用机制来看，数字经济发展能够通过促进技术创新和经济集聚来提升生态韧性，并且政府对新质生产力关注度的提高强化了数字经济发展在提升生态韧性方面的作用。进一步研究发现，数字经济发展能够提升城市的生态韧性，且具有显著的空间溢出特征，即数字经济发展不仅能够提升本城市的生态韧性，还有助于提升邻近城市的生态韧性。异质性检验表明，数字经济发展对生态韧性的增强效应因城市地理位置、行政级别和资源禀赋的异质性而存在差异，即相较于东部、中部和资源型城市，中西部、边缘和非资源型城市的数字经济发展对生态韧性的增强效应更大。研究结论可为中国厘清提升生态韧性的作用机制提供有益启示，为区域合作增强生态韧性提供政策依据。
