摘要
基于技术异质性框架构建了包含非期望产出的共同前沿模型,用于测算2011—2021年间中国47个物流枢纽两阶段生态效率及其影响因素。研究发现:物流枢纽的生态效率呈波动上升趋势,不同类型物流枢纽的生态效率的技术异质性明显,且物流枢纽之间两阶段的技术差距呈上升趋势。无效率分解发现,物流枢纽的生态无效率是技术无效和管理无效共同所致,而不同类型物流枢纽的生态效率损失根源较为复杂。影响因素分析发现,整体上城市经济水平和环境规制对生态效率具有显著促进作用,产业聚集和政府支持对生态效率的促进作用不显著,而能源结构和对外直接投资对生态效率具有显著抑制作用。
Drawing on the technological heterogeneity framework,this paper develops a common-frontier efficiency model that incorporates undesirable outputs to estimate the ecological efficiency of production and waste treatment at 47 Chinese logistics hubs over 2011-2021.It then examines the key factors driving efficiency losses.The results show that eco-efficiency has exhibited an overall upward trend:the average scores for the production and waste-treatment stages were 0.698 and 0.593,respectively.Significant heterogeneity exists across hub types,and the technological gap between the two stages has widened over time.Overall ecological inefficiencies stem from both technological shortcomings and managerial deficiencies.Moreover,regression analysis indicates that urban economic level and environmental regulation significantly boost eco-efficiency;in contrast,energy structure and OFDI exert a significant negative effect,whereas indus-trial agglomeration and government support show no significant impact.
