Abstract

Land is an essential resource to underpin the development of urban agglomerations. Spatial configuration of urban agglomerations is extensively viewed as playing a vital role in influencing land use efficiency (LUE). However, little research has been done to explore whether spatial configuration affects LUE in a nonlinear manner, and few studies have investigated whether effects of spatial configuration on LUE varies across different transport network connectivity. This paper characterizes spatial configuration of urban agglomerations based on a bidimensional analysis, and examines nonlinear effects of spatial configuration on LUE, the heterogeneous effects under different transport network connectivity and mechanisms of influence, using data for major urban agglomerations in China. The results show that both the relationship between agglomeration level and LUE and that between polycentricity level and LUE follows a pattern of inverted U. The inflection point on the agglomeration level-LUE curve emerges earlier in urban agglomerations with stronger transport connectivity. The inflection point on the polycentricity level-LUE curve emerges later under stronger transport connectivity. Spatial configuration affects LUE through influencing infrastructure level, innovation generation and human capital level. The findings have important policy implications for driving optimization of spatial configuration of urban agglomerations and enhancing LUE.

城市群空间格局与土地利用效率的关系研究——基于交通网络连通的二维分析

土地是支撑城市群发展的重要资源。城市群的空间结构被广泛认为对土地利用效率起着至关重要的作用。然而，很少有研究探讨空间配置是否以非线性方式影响LUE，也很少有研究探讨空间配置对LUE的影响是否因不同的传输网络连通性而变化。本文以中国主要城市群为研究对象，基于二维分析对城市群空间配置特征进行了刻画，并探讨了空间配置对城市效率的非线性效应、不同交通网络连通性下的异质性效应及其影响机制。结果表明：城市群集聚水平和多中心性水平与LUE的关系均呈倒u型，交通连通性越强的城市群集聚水平-LUE曲线拐点出现越早；在运输连通性较强的条件下，多中心水平lue曲线的拐点出现较晚。空间配置通过影响基础设施水平、创新产生水平和人力资本水平来影响LUE。研究结果对推动城市群空间结构优化、提高城市效率具有重要的政策意义。

期刊介绍： Cities offers a comprehensive range of articles on all aspects of urban policy. It provides an international and interdisciplinary platform for the exchange of ideas and information between urban planners and policy makers from national and local government, non-government organizations, academia and consultancy. The primary aims of the journal are to analyse and assess past and present urban development and management as a reflection of effective, ineffective and non-existent planning policies; and the promotion of the implementation of appropriate urban policies in both the developed and the developing world.
