The impact of local government environmental target constraints on urban land green use efficiency
理解地方政府环境目标约束对城市土地绿色利用效率的影响,有助于推动经济、社会与生态的协调发展.基于2003-2021 年中国282 个地级市政府工作报告中的环境目标约束数据,运用非期望产出超效率SBM模型测算城市土地绿色利用效率,并运用双重差分法评估环境目标约束的效果.研究表明:地方政府设定的环境目标约束显著提升了城市土地绿色利用效率,且该结论在稳健性和安慰剂检验中得到验证;环境目标约束通过强化环境规制、减少污染排放,有效推动了土地的绿色利用;同时,政策效果在不同区域间存在差异.基于此,建议创新生态政绩考核机制,完善环境规制政策,并根据区域特征实施精准化土地利用策略,以进一步提升城市土地绿色利用效率.
Understanding how local government environmental target constraints influence urban land green use efficiency helps ad-vance coordinated development across the economy,society,and ecology.Based on environmental target data extracted from government work reports of 282 prefecture-level cities in China from 2003 to 2021,this paper applied a super-efficiency SBM model with unde-sirable outputs to evaluate green land use efficiency and used a difference-in-differences(DID)approach to estimate policy effects.The results showed that these constraints significantly improved urban green land use efficiency,with the conclusion confirmed through robustness and placebo tests.Further analysis revealed that the constraints drive green land use by enhancing environmental regulation and reducing pollution emissions.The effects also varied across regions.These findings highlight the need to reform ecological perform-ance assessments,refine regulatory tools,and tailor land use policies to regional characteristics to further boost urban green land use effi-ciency.
