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.
提高城市绿地利用效率是推动中国绿色可持续发展的关键。厘清经济增长目标管理对城市绿地利用效率的影响及其作用机制，对于提高城市绿地利用效率具有重要意义。本文选取2010—2021年中国273个城市作为研究样本，运用面板数据模型和空间杜宾模型实证检验经济增长目标管理（包括经济增长目标值、经济增长目标硬约束和软约束）对城市绿地利用效率的影响、传导机制及空间溢出效应。此外，本文运用面板门槛模型验证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作用。研究发现：（1）地方经济增长目标值及其硬约束对城市绿地利用效率具有负面影响，而软约束有利于提高城市绿地利用效率。（2）绿色技术创新和产业结构升级是主要传导渠道。（3）随着环境规制强度的增加，经济增长目标值及其硬约束对城市绿地利用效率的负面影响减弱，而其软约束对城市绿地利用效率的正面影响增强。（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，而其软约束则会提高本地区的城市绿地利用效率。（5）经济增长目标对中部地区和资源型城市的城市绿地利用效率负面影响最大。未来，应降低GDP增长率在官员绩效考核中的重要性，采用更灵活的“软约束”来设定经济增长目标。
