Improving urban green land utilization efficiency (UGLUE) is the key to promoting green and sustainable development in China. Clarifying the impact of economic growth target management (EGTM) on UGLUE and its mechanism of action is of great significance to improving UGLUE. Selecting 273 cities in China from 2010 to 2021 as the research sample, this paper uses panel data model, and spatial Durbin model (SDM) to empirically examine the impact, transmission mechanism and spatial spillover effect of EGTM (including economic growth target values, hard constraints and soft constraints of economic growth targets) on UGLUE. In addition, this paper uses panel threshold model to verify the threshold role of environmental regulation in the relationship between EGTM and UGLUE. The research found that: (1) Local economic growth target value and its hard constraints have a negative impact on UGLUE, while soft constraints are conducive to improving UGLUE. (2) Green technology innovation and industrial structure upgrading are the main transmission channels. (3) As the intensity of environmental regulation increases, the negative impact of economic growth target value and its hard constraints on UGLUE weakens, while the positive impact of its soft constraints on UGLUE strengthens. (4) The economic growth target value and its hard constraints of surrounding areas can reduce the UGLUE in the region, while its soft constraints can improve the UGLUE in the region. (5) Economic growth targets have the greatest negative impact on UGLUE in the central region and resource-based cities. In the future, the importance of GDP growth rate in official performance evaluations should be reduced. More flexible “soft constraints” should be used to set economic growth targets.

提升城市绿地利用效率（urban green land utilization efficiency, UGLUE）是推动我国绿色可持续发展的关键之举。厘清经济增长目标管理（economic growth target management, EGTM）对城市绿地利用效率的影响及其作用机制，对于提升城市绿地利用效率具有重要意义。本文以2010—2021年中国273个城市为研究样本，采用面板数据模型与空间杜宾模型（spatial Durbin model, SDM），实证考察了经济增长目标管理（涵盖经济增长目标值、经济增长硬约束与软约束）对城市绿地利用效率的影响、传导机制与空间溢出效应。此外，本文借助面板门槛模型，验证了环境规制在经济增长目标管理与城市绿地利用效率关系中的门槛效应。研究结果表明：（1）地方经济增长目标值及其硬约束对城市绿地利用效率产生负向影响，而软约束则有助于提升城市绿地利用效率；（2）绿色技术创新与产业结构升级是主要的传导渠道；（3）随着环境规制强度的提升，经济增长目标值及其硬约束对城市绿地利用效率的负向影响逐渐减弱，而软约束对城市绿地利用效率的正向影响则不断增强；（4）周边地区的经济增长目标值及其硬约束会降低本地区的城市绿地利用效率，而周边地区的软约束则会提升本地区的城市绿地利用效率；（5）经济增长目标对中部地区与资源型城市的城市绿地利用效率负向影响最为显著。未来应降低GDP增速在官员绩效考核中的权重，采用更具灵活性的“软约束”方式设定经济增长目标。
