[Mechanism and Effect of Digital Economy Development on Ecological Resilience]

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.
