Manufacturing agglomeration (MA) is an important way to achieve high-quality industrial development and promote land use efficiency in China. However, there is a lack of research on the relationship between MA and the green use efficiency of industrial land (GUEIL). Based on the panel data of 279 prefecture-level cities in China, from 2004 to 2019, this study analyzes the spatial and temporal differentiation characteristics of MA and GUEIL, then empirically analyzes the impact of MA on GUEIL. The results show that: (1) during the study period, the national MA levels showed a slight decline, followed by a small increase. In addition, the inter-regional differences are mainly characterized as eastern region > central region > northeast region > western region. (2) The national and regional GUEIL showed a trend of increasing, slightly decreasing, and then increasing again. The overall regional differences in efficiency show the characteristics of: eastern region > central region > western region > northeastern region. (3) At the national scale, MA had a “U-shaped” relationship with GUEIL; at the regional scale, MA had a significant “U-shaped” effect on GUEIL in the northeast, central and western regions, while having a single negative effect in the eastern region. Finally, this study provides suggestions for optimizing the manufacturing structure and improving the GUEIL.
制造业集聚（MA）是实现中国高质量工业发展和提高土地利用效率的重要途径。然而，关于 MA 与工业用地绿色利用效率（GUEIL）之间的关系的研究还很缺乏。本研究基于 2004 年至 2019 年中国 279 个地级市的面板数据，分析了 MA 和 GUEIL 的时空分异特征，然后实证分析了 MA 对 GUEIL 的影响。结果表明：（1）在研究期间，全国 MA 水平呈轻微下降趋势，随后略有上升。此外，区域间差异主要表现为东部地区>中部地区>东北地区>西部地区。（2）全国和各地区的 GUEIL 呈增长、略有下降、再增长的趋势。效率的整体区域差异表现出东部地区>中部地区>西部地区>东北地区的特点。（3）在全国范围内，MA 与 GUEIL 呈“U 型”关系；在区域层面上，MA 对东北地区、中部地区和西部地区的 GUEIL 具有显著的“U 型”效应，而在东部地区则具有单一的负向效应。最后，本研究为优化制造业结构和提高 GUEIL 提供了建议。
