In the new stage of China’s economic development, significant transformations have occurred in the mode, emphasis and speed of urban development. Enhancing the level of livelihood public service and promoting the green development of cities have emerged as the prevailing themes of contemporary urban development. Based on a theoretical model analysis, using the panel data of 281 cities in China from 2007 to 2020, this paper adopts the fixed-effect model for empirical analysis. The study revealed the following four main points. (1) The provision of livelihood public services can effectively enhance the efficiency of urban green development. After conducting a series of robustness tests, this conclusion is still valid. (2) The provision of livelihood public services only fosters the green transformation of non-resource-based cities, while its impact on resource-based cities remains non-significant. (3) The mechanism test demonstrated that livelihood public services promote green development efficiency mainly through population, innovation and producer services agglomeration. (4) The threshold effect test showed that there are differences in the nonlinear relationship between the livelihood public service level and urban green development efficiency under different threshold variables.

在高质量发展的新阶段，城市的发展模式、发展重心和发展速度已发生了深刻的改变，改善民生性公共服务，推 动绿色发展成为当前城市发展的主旋律。在理论模型的基础上，选取 2007–2020 年 281 个城市面板数据，采用固定效应模型实证 研究发现：（1）民生性公共服务供给能够显著提高城市绿色发展效率，经过一系列的稳健性检验后，结论依然成立。（2）民生 性公共服务仅仅促进了非资源型城市绿色转型，而对资源型城市并没有显著影响。（3）机制检验表明民生性公共服务主要通过 人口集聚、创新集聚和生产性服务业集聚促进绿色发展效率提升。（4）门槛效应检验表明，不同门槛变量下，民生性公共服务 水平与城市绿色发展效率间的非线性关系存在差异。
