工业用地错配引发的效率损失是制约中国区域一体化和经济高质量发展的关键问题。基于2010—2023年京津冀与长三角城市群面板数据，构建“政府干预—工业用地错配—效率损失”的分析框架，采用超效率SBM模型测度工业用地利用效率，并结合面板Tobit模型与中介效应模型系统检验工业用地错配的影响效应及其作用机制。研究发现：(1)政府干预下城市群的工业用地错配对工业用地利用效率具有显著抑制作用，呈现明显的制度性扭曲特征；(2)效率损失存在显著区域异质性，京津冀地区负效应强于长三角，其根源在于政府干预目标差异，即前者以功能疏解与区域协同发展为导向，导致空间配置失序，后者以区域竞争和经济效率提升为导向，主要表现为要素价格扭曲；(3)工业用地错配通过“技术创新抑制—产业结构固化—集聚经济稀释”3条路径降低效率，但传导重点存在区域分化：京津冀以“集聚经济稀释”为核心路径，长三角更多依赖“技术创新抑制”与“产业结构固化”双路径驱动。研究结果可为推进土地要素市场化改革和实施差异化区域治理提供理论依据与政策启示。

Efficiency loss arising from industrial land misallocation has become a critical constraint to regional integration and high-quality development in China.Based on panel data of the Beijing-Tianjin-Hebei(BTH) and the Yangtze River Delta(YRD) urban agglomerations from 2010 to 2023,this study constructs an integrated analytical framework of "government intervention-industrial land misallocation-efficiency loss" to systematically examine the effects and transmission mechanisms.Methodologically, industrial land use efficiency is measured using a super-efficiency slack-based measure model with undesirable outputs, which improves the accuracy of efficiency evaluation under environmental constraints.A panel Tobit model is further employed to address the censored nature of efficiency scores, and mediation effect models are introduced to identify multi-dimensional transmission channels, forming a systematic empirical strategy that integrates efficiency measurement, causal inference, and mechanism decomposition.The findings are as follows.(1) Under government intervention, industrial land misallocation in both urban agglomerations significantly inhibits industrial land-use efficiency, exhibiting pronounced institutional distortions.(2) The adverse effects exhibit marked regional heterogeneity, with a stronger negative impact in the BTH than in the YRD.This divergence is rooted in differing government objectives: the BTH prioritizes functional decentralization and regional collaboration and development, leading to spatial disorganization, whereas the YRD emphasizes interregional competition and economic efficiency, manifesting chiefly as factor price distortions.(3)Mechanism analysis further reveals that industrial land misallocation reduces industrial land-use efficiency through three pathways: suppressing technological innovation, rigidifying industrial structure, and diluting agglomeration economies.Yet the dominant pathways differ across regions: agglomeration dilution serves as the core channel in the BTH,while innovation suppression and industrial structural rigidification jointly drive efficiency losses in the YRD.This study provides a theoretical basis and policy implications for advancing market-oriented reforms of land factors and implementing differentiated regional governance.
