Abstract

The effect of urban shrinkage has gradually become a new topic. Theoretically, urban shrinkage may exert great influence on land use efficiency (LUE) through various urban subsystems, but there is currently limited research examining these pathways. Using the Super-SBM-Undesirable model and the Structural Equation Model (SEM), this study calculates the LUE of shrinking cities in Northeast China and simulates the process of urban shrinkage affecting LUE. To quantify the process of urban shrinkage affecting LUE, three mediation variables, namely the economy, public services, and innovation, are used as latent variables to apply SEM. The results show that urban shrinkage will affect LUE through a direct path and indirect paths. In the direct path, urban shrinkage leads to an improvement in LUE. In the indirect paths, the economy and innovation will transmit the negative effect of urban shrinkage on LUE, while public services will reverse this effect. An important contribution of this study is that it quantifies the paths of urban shrinkage affecting LUE, thereby expanding the understanding of urban shrinkage effect and laying a foundation for the sustainable development of shrinking cities.

城市萎缩如何影响土地利用效率？中国东北地区萎缩城市案例研究

摘要城市收缩的影响已逐渐成为一个新课题。从理论上讲，城市萎缩可能通过各种城市子系统对土地利用效率（LUE）产生巨大影响，但目前对这些途径的研究还很有限。本研究利用超级-SBM-不理想模型和结构方程模型（SEM），计算了中国东北地区萎缩城市的土地利用效率，并模拟了城市萎缩对土地利用效率的影响过程。为量化城市萎缩对LUE的影响过程，将经济、公共服务和创新三个中介变量作为潜变量，应用SEM进行分析。结果显示，城市萎缩将通过直接路径和间接路径影响 LUE。在直接路径中，城市萎缩会导致 LUE 的改善。在间接路径中，经济和创新将传递城市萎缩对 LUE 的负面影响，而公共服务将扭转这种影响。本研究的重要贡献在于量化了城市萎缩对 LUE 的影响路径，从而拓展了对城市萎缩效应的认识，为萎缩城市的可持续发展奠定了基础。

期刊介绍： Chinese Geographical Science is an international journal, sponsored by Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, and published by Science Press, Beijing, China. Chinese Geographical Science is devoted to leading scientific and technological innovation in geography, serving development in China, and promoting international scientific exchange. The journal mainly covers physical geography and its sub-disciplines, human geography and its sub-disciplines, cartography, remote sensing, and geographic information systems. It pays close attention to the major issues the world is concerned with, such as the man-land relationship, population, resources, environment, globalization and regional development.
