摘要
优化土地利用效率是高质量发展理念下协调资源约束与生态保护的关键路径。在构建城市土地绿色利用效率内涵框架的基础上,基于含非期望产出的超效率SBM模型,测度并分析河北省11个地级市2010—2021年的土地绿色利用效率与时空演变特征。研究发现:时序演变呈现“波动上升—调整优化—趋稳提质”的阶段性特征;空间格局形成“双核引领、沿海跃升、内陆分化”的梯度分布。其中,石家庄、唐山依托创新驱动与港口转型成为高效核心区,而邢台、邯郸因重工业依赖与污染问题深陷低效洼地。基于此,研究提出构建跨区域土地要素共享机制、推动重工业用地绿色转型及深化沿海生态协同治理等优化策略,为河北省统筹高质量发展与生态保护提供科学依据。
Optimizing land use efficiency is a crucial pathway for coordinating resource constraints and ecological protection under the high-quality development paradigm.This study establishes a conceptual framework for urban green land use efficiency and employs a super-efficiency SBM model,which incorporates undesirable outputs to measure and analyze the spatial-temporal evolution characteristics of green land use efficiency across 11 prefecture-level cities in Hebei Province from 2010 to 2021.Key findings reveal that temporal evolution exhibits a three-stage trajectory:“fluctuating rise,structural optimization,and stable enhancement.”Spatially,a gradient pattern emerges characterized by“dual-core leadership,coastal leapfrogging,and inland divergence.”Shijiazhuang City and Tangshan City have emerged as high-efficiency core areas driven by innovation and port transformation,whereas Xingtai City and Handan City remain trapped in low-efficiency zones due to heavy industrial reliance and pollution challenges.Based on these insights,the study proposes optimization strategies,including establishing a cross-regional land element sharing mechanism,promoting green transition of heavy industrial land,and deepening coastal ecological collaborative governance.These recommendations provide scientific foundations for Hebei Province to balance high-quality development with ecological preservation.
