At present, the insufficient supply of land resources has seriously hindered the sustainable development of regional economy. Improving the urban green land use efficiency (UGLUE) has become a key issue on the road to sustainable development. As an important feature of economic development, industrial agglomeration has an impact on the UGLUE that cannot be ignored. This paper uses the Global Malmquist-Luenberger Index (GMLI) to measure UGLUE of 107 cities in the Yangtze River Economic Belt (YREB) from 2007 to 2016, and uses a dynamic panel model (DPM) to empirically analyze the effects of industrial specialization agglomeration and diversification agglomeration on UGLUE. On this basis, the heterogeneous impact of industrial agglomeration in different regions on UGLUE is further discussed. The results illustrate that: (1) The UGLUE shows a general downward trend. (2) Different modes of industrial agglomeration have different impacts on UGLUE. The impact of industrial specialization agglomeration on UGLUE was inverted U-shaped. Industrial diversification agglomeration has a positive effect on UGLUE. (3) The impact of industrial agglomeration in different regions on UGLUE is heterogeneous. The relationship between the industrial agglomeration and UGLUE in the YREB revealed in this paper will provide a reference for promoting UGLUE.
目前，土地资源供给不足严重制约了区域经济的可持续发展。提高城市绿地利用效率（UGLUE）已成为可持续发展道路上的关键问题。产业集聚作为经济发展的重要特征，其对 UGLUE 的影响不容忽视。本文利用全局 Malmquist-Luenberger 指数（GMLI）测算了 2007—2016 年长江经济带（YREB）107 个城市的 UGLUE，并利用动态面板模型（DPM）实证分析了产业专业化集聚和多样化集聚对 UGLUE 的影响。在此基础上，进一步探讨了产业集聚在不同地区对 UGLUE 的异质性影响。结果表明：（1）UGLUE 呈普遍下降趋势。（2）不同模式的产业集聚对 UGLUE 的影响不同。产业专业化集聚对 UGLUE 的影响呈倒 U 型。产业多样化集聚对 UGLUE 有正向影响。（3）产业集聚在不同地区对 UGLUE 的影响存在异质性。本文揭示的长江经济带产业集聚与 UGLUE 的关系为促进 UGLUE 提供了参考。
