| 中文摘要 |
| 在国家高度重视生态文明建设与绿色发展的背景下，利用2011~2022年中国286个地级及以上城市的面板数据解析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，该结果在经过一系列稳健性检验后仍然成立，且数字经济发展对生态韧性的提升效应具有边际递增的非线性特征；就其作用机制而言，数字经济发展能够通过促进技术创新和经济集聚提升生态韧性，且政府新质生产力关注度提高强化了数字经济发展对生态韧性的提升作用；进一步研究发现数字经济发展提升生态韧性具有显著的空间溢出特征，即数字经济发展不仅可以提升本城市生态韧性，也有助于提升邻近城市的生态韧性；异质性检验表明，与东部、中心和资源型城市相比，在中西部、外围和非资源型城市数字经济发展对生态韧性具有更大的提升效应. 研究结论可为中国明确提升生态韧性的机制提供了有益启示且为地区之间协作强化生态韧性提供了政策依据. |

| 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. |
