【摘要】 采用区位熵法、超效率SBM-UN(非期望SBM)模型以及面板Tobit模型，探索县域层面产业集聚对土地利用效率的影响机制。研究结果表明：内蒙古县域第二产业的集聚程度先升后降，第三产业的聚集程度先降后升；内蒙古县域土地利用效率总体呈现先减少后增加的变化趋势，且高值区域逐渐向中心集中；内蒙古县域产业集聚对土地利用效率起到了正向驱动效应，其影响机制呈现明显的异质性，经济发展水平和人口密度对土地利用效率的提高有显著的促进作用，而土地利用结构、消费水平和企业规模对土地利用效率的提高起到负向阻滞作用；各旗县(区)因资源禀赋差异以及经济发展程度等方面的影响，导致产业集聚水平及土地利用效率的差异较大。未来应继续加强产业集聚的引导和规划，优化土地资源配置。更多还原

【Abstract】 The location entropy method, super efficiency SBM-UN model, and panel Tobit model were adopted to explore the impact mechanism of county-level industrial agglomeration on land use efficiency. The research results indicate that the agglomeration degree of the secondary industry in Inner Mongolia counties first increased and then decreased, and the agglomeration degree of the tertiary industry first decreased and then increased. The overall trend of land use efficiency in Inner Mongolia’s counties shows a decrease followed by an increase, with high-value areas gradually concentrating towards the center. The agglomeration of county-level industries in Inner Mongolia has a positive driving effect on land use efficiency, and its impact mechanism is significantly heterogeneous. The level of economic development and population density have a significant promoting effect on the improvement of land use efficiency, while land use structure, consumption level, and enterprise size have a negative hindering effect on the improvement of land use efficiency. Due to differences in resource endowments and economic development levels, various counties(districts) have significant differences in industrial agglomeration levels and land use efficiency. In the future, it is necessary to continue to strengthen the guidance and planning of industrial agglomeration, and optimize the allocation of land resources.更多还原
