Based on the panel data of 257 prefecture-level cities in China from 2010 to 2017, this paper measured urban land green use efficiency (ULGUE), incorporating undesirable outputs, via the super efficiency slack-based model (SBM). It also explored the effect, mechanism, and heterogeneity of growth targets management and regional competition on ULGUE via the time-varying gravitational spatial weight matrix and the spatial self-lagging model. The results show that growth targets management and regional competition have significant positive effects on ULGUE, and enhance the ULGUE by promoting local investment attraction, increasing innovation inputs, optimizing environmental regulations and strengthening commercial activities. Additionally, growth targets management has a more significant effect on eastern cities, non-central cities, and mature urban agglomeration, while regional competition has a more significant effect on central cities, non-central cities, and developmental urban agglomeration. Therefore, considering development as the priority, setting relatively aggressive economic growth targets and optimizing the regional competition mechanism for growth targets management can help improve the ULGUE and promote high-quality economic development in China.
基于 2010 年至 2017 年中国 257 个地级市的面板数据，本文采用超效率 slack 基准模型（SBM），纳入非期望产出，测算了城市土地绿色利用效率（ULGUE）。通过时变引力空间权重矩阵和空间自滞后模型，探讨了增长目标管理和区域竞争对 ULGUE 的影响、作用机制和异质性。结果表明，增长目标管理和区域竞争对 ULGUE 具有显著的正向影响，通过促进地方投资吸引力、增加创新投入、优化环境规制和加强商业活动，提高了 ULGUE。此外，增长目标管理对东部城市、非中心城市和成熟城市群的影响更为显著，而区域竞争对中心城市、非中心城市和发展中城市群的影响更为显著。因此，在考虑发展优先的前提下，制定相对积极的经济增长目标，优化增长目标管理的区域竞争机制，有助于提高 ULGUE，促进中国经济的高质量发展。
