The ecological resilience of resource-based cities reflects the resilience of the ecological environment in resource-based areas to recover after resource development activities, and good ecological resilience holds great significance for the sustainability of the development of resource-based cities. Government innovation preferences are a solid foundation for implementing an innovation-driven strategy and an important guarantee for realizing an efficient production mode. (the purpose of the study) Therefore, to investigate whether government innovation preferences can promote the level of ecological resilience in resource-based cities. (sample information and empirical methods) This paper establishes a mediating effect model and a threshold effect model and empirically analyzes 2009-2020 panel data covering 113 resource-based cities in China as an example. (main findings) The results show the following: (1) the primary term of government innovation preferences has a positive effect on the ecological resilience of resource-based cities, and the secondary term has a negative effect, with a decreasing marginal effect. Additionally, the educational level has a mediating effect on the mechanism of the impact of government innovation preferences on the ecological resilience of resource-based cities. (2) The role of government innovation preferences in the ecological resilience of resource-based cities is heterogeneous: The impact of government innovation preferences on the ecological resilience of resource-based cities in the western region is stronger than that in the central region, and the impact of government innovation preferences on the ecological resilience of medium-sized resource-based cities is stronger than that of large resource-based cities. (3) The role of environmental decentralization produces a single threshold effect with a threshold value of 2.3993 in the impact of the mechanism of government innovation preferences on the ecological resilience of resource-based cities. (contributions and policy implications) The results of this paper can provide theoretical support for the government to set a reasonable innovation preference intensity, and they provide a practical guarantee for the central government to give more environmental governance power to local governments.
资源型城市生态韧性反映了资源型地区生态环境在资源开发活动后恢复的能力，良好的生态韧性对资源型城市的可持续发展具有重要意义。政府创新偏好是实施创新驱动战略的坚实基础，也是实现高效生产模式的重要保障。（研究目的）因此，本文旨在探讨政府创新偏好是否能提升资源型城市的生态韧性水平。（样本信息和实证方法）本文构建了中介效应模型和门槛效应模型，以中国 113 个资源型城市 2009-2020 年的面板数据为例进行实证分析。（主要发现）结果表明：（1）政府创新偏好的初始项对资源型城市的生态韧性有正向影响，二次项有负向影响，且存在边际递减效应，教育水平在政府创新偏好影响资源型城市生态韧性的机制中起中介作用；（2）政府创新偏好在资源型城市生态韧性中的作用具有异质性：政府创新偏好对西部地区资源型城市生态韧性的影响大于中部地区，对中等规模资源型城市生态韧性的影响大于大规模资源型城市；（3）环境分权的作用存在单一门槛效应，其在政府创新偏好影响资源型城市生态韧性的机制中存在 2.3993 的门槛值。（贡献与政策启示）本文的研究结果可为政府合理设定创新偏好强度提供理论支撑，为中央政府赋予地方政府更多环境治理权力提供实践保障。
